Stove flexible reinforced for hot water. Features of flexible eyeliner for water. Hoses are the type of load

The hoses are made from non-toxic ethylene propylene rubber, which is resistant to corrosion and high temperature. For braid applies steel thread. It provides high mechanical strength, including in the inflection and the gap, protects against hydraulic shocks. Such a hose is designed for working pressure up to 20 atmospheres. It is used in drinking water supply systems, for the organization of heating and hot water supply.

Manufacturers offer products with different size Passage section. For selection the desired diameter It is important to know the predicted water consumption. In most water supply and heating systems, hoses are used with an internal diameter of 8 mm.

Silphon submarine

Products are performed from corrugated metal sleeves. Connecting sleeves are welded directly to the liner's sleeve itself. Such products have a long service life (up to 25 years). Corrugated hose is resistant to pressure drops and withstand hydraulic shocks. However, when used in systems with variable loads, microcracks appear on the corrugation. For rigid conditions of operation, manufacturers offer a variant of corrugated pipes protected by steel braid.

The bellows liner is most in demand for transporting liquids at temperatures from +50 to +250 ° C. In everyday life, flexible gofrots did not find applications due to the fact that with a large stream of water, they are strongly buzzing and vibrate.

What is dangerous poor-quality stamp for the mixer?

When choosing plumbing products of dubious manufacturers, you risk spending money in vain.

Major problems of low-quality products:

flow at the place of attachment of the connective nut;
condensate formation;
cut the hose in the place of fastening the sleeve.

The company "Mir of Plumbing" offers a huge selection of products of domestic and foreign manufacturers. You can buy them with delivery in Moscow, MO, as well as other regions of the Russian Federation. When placing an order, focus on the diameter, the type of connective nuts and the length of the hoses.

The bellows liner for water is a corrugated sleeve of a special qualitative, such a device is very convenient, but it should be remembered that it is not so flexible as the rubberometallic hose. Silphon eyeliners are used to connect water, air conditioners, gas and plumbing devices such as washing, shower, cistern. Flexible hoses in water supply systems are installed in the last plots of water supply, joined the highway to devices with which the consumer interacts.

The modern market offers to choose a large number of bellows from different manufacturers of manufacturers who differ in price categories, models, functional purpose, color, size, quality, duration of service. Such hoses are very convenient to everyday life and are always popular with consumers. Now you can safely forget about outdated metal pipes. Almost always during the repair or renewal of plumbing uses a bellows liner for water. Customer reviews about these devices are only positive. With the use of high-quality materials on the background, all household problems are departed.

Selection of eyelid

First of all, the quality of the materials that were used by the manufacturer for the manufacture of eyeliner should be taken into account. It is worth paying attention to the products of Italian firms made of durable high-quality materials, aluminum and stainless steel. Holding many manufacturers, having good technical indicators, are distinguished by the available price. Some manufacturers are developing an anti-vibration liner having a large diameter and delivering from noise and hum when connected to home appliances. Such adaptations have no analogues in the domestic market.

Popular manufacturers

The main manufacturers of such supply are Witzenman, Pagri, G-Beka and Hydraflex trademarks. If a boiler is used in the bathroom or some other plumbing, not to avoid the presence of devices that will rush into the eyes. In such situations, the bellows liner for Hydraflex water is recommended. Products of this company have a modern neat appearance, complementing the aesthetic design of the bathroom.

Such eyelbs are definitely high-quality and can serve customers much longer than ordinary flexible hoses. These devices can be used as for cold waterand for hot. It should be borne in mind that the cost of branded liner is several times higher than usual.

Appearance

From the proposed range, it is recommended to give preference to hoses, in which the fitting nuts are made of austenitic steel, since brass quality is very low. You can recognize this material in cracks and dents. The seam between the spiral part and the fitting should be carried out by means of argon-arc welding, and not by the rolling method, like on carved liners. Dark spots - This is a rust, and too rounded shape of the joints indicates the unreliability and the inclination of the material to oxidation. Good seams have a thin and even profile and almost do not differ in the color from the hose.

A high-quality eyeliner for the water of a bellows type does not have dents, spots of rust or chip. Their presence indicates the use of base steel. This is considered a sign of poor metal strength. The protected eyeliner has, as a rule, coating from PVC film. The difference between the products for gas and water is most often consigned to the rigidity of the spirals due to the calculation of interaction with large or less pressure. This is checked by the method of ordinary stretching of the hose.

Features of operation

Many manufacturers officially ensure that their hoses will serve 15 years. A good bellows for water for water "Aquaprof", for example, can be easily operated for 30-35 years, and with gentle operation modes, this indicator is stretched to fifty. The service life also depends on the fitting materials. The minimum service duration is observed in the elements made of carbon steel and brass. Stainless steel nuts are the most durable, if you compare them with other materials.

The design of the spiral makes it possible to twist the hose, and the fold will be fixed. A high-quality bellows stainless steel bellows can stretch in length without risk 1.5-2 times. Due to the rigidity of the corrugated structure, its diameter should not change. Choosing a hose, you can ask the seller to step onto the eyeliner or put some cargo for it.

Benefits

The modern bellows liner for water makes it possible to quickly install plumbing, various water supply, gas and heating equipment in the most hard-to-reach places at the cottage, in the cottage, apartment or office. High-quality hoses have high technical indicators, anti-vibration properties and are indispensable to organize comfortable conditions in any room. Wonderful aesthetic properties of flexible eyeliner make it possible to emphasize stylish interior Apartments or office.

What is the difference between the bellows liner for water from metal pipes?

Long familiar iron pipes are used less often. When connecting water supply, heaters, bidets and other devices, bellows made of polymeric materials, rubber and metal are increasingly used. Such water supply is very flexible, does not rust, resistant to different aggressive environments, as well as temperature drops, has an increased duration of the service.

Stovetub construction

The hose is an essential element of the bellows. It can be made of non-toxic rubber of different brands, as well as other materials. The components used should be environmentally friendly, not to form on the walls of malicious compounds and withstand relatively high temperatures. Rubber hoses are protected outside the braid of stainless steel, aluminum and other materials so that the bellows liner for water is not subject to mechanical effects and has quite high strength.

All connecting elements are fittings, nuts with a gasket, nipple should always be made of sufficiently high-quality materials.

In the era of modern construction and sanitary materials no longer have to break their heads over, as and where to place a convenient and nonsense plumbing. Soft flexible flexible hoses enclosed in a durable case came to replace standard hard tubes. These details are serve long years given that right choice and operation.

Features

Flexible submarine It has a number of features, among which are easily positive. But negative nuances should also be mentioned to avoid unpleasant sediment, excess time, forces and money.

Pluses of this flexible liner:

complete tightness and protection against the course;
saving the area of \u200b\u200bthe room, which allows you to install additional interior items or equipment without regard to bulky pipes;

ease in changing the location of a flexible supply of the subject;
refusal to use the welding machine;
the protection of the hose from the hydroudars (in case the pressure leap occurs in the water supply system, the high-quality flexible lining is protected from breaking and leakage of water);
easy installation and operation (all major works can be made independently).

Flexible eyeliner is usually used for various water connections.Most often it is used in the bathrooms (connecting to the water toilet bowl, mixer, boiler) and in the kitchens.

As for negative gradation estimates, most often users complain about problems resulting from improper hose installation. To avoid this, experts advise to acquire the product only a well-known manufacturer. Also guarantee shopping good quality It will be a thorough inspection of the product still in the store (before you purchased it).

When choosing to pay attention to several important points.

Weight eyeliner should not be easier than a row. If you're in your hand it is such a product, immediately put it in place. At best, this slog will serve you a couple of weeks after installation.
Flexible eyeliner should be easily stuffed in different directions. If you have to make an effort to change the shape of the hose, you can safely put it aside and take on the other, since this is made of low-quality technical rubber, which can simply be repaid from the bends.

Another significant disadvantage is the low life of the plastic fitting. To accurately choose exactly low-eyed, Consider the main characteristics of this product.

Specifications

To date, there are two categories of flexible water supply: extension cords and adapters. The second are standard hoses that connect the necessary devices to water supply: washing, toilets, shower cabins and boilers. Usually they have a length of up to 60 cm. Extension cords are auxiliary hose that connects to the adapter to provide water the most remote areas.

The service life of any liner hose depends on both the starting quality of the product and the correctness of its installation and operation.

By purchasing a flexible bathroom, pay attention to the presence of color strips on the reinforced surface:

red testifies to the possibility of using only hot water;
blue can only be used in cold water conditions;
both bands immediately indicate that the hose can be installed for feeding and hot and cold water.

Thus, when connecting the crane or toilet to the place where only cold water is always used, all three types of flexible liner can be used. If we are talking about a mixer with two temperature modes, a boiler or radiator, the use of hoses with a blue strip is strictly prohibited here.

There are also flexible liners with a yellow strip along the entire length of the hose.They are intended only for connecting users to gas supply and have special impregnation and lubricants inside, which are unacceptable to use with water, especially drinking or washed. The water pasted through this hose is considered technical and has dangerous impurities for human health.

It is worth staying on the main types of flexible supply, existing today in the construction market.

Views

Modern manufacturers offer a wide range of connecting plumbing tubes. Their classification is made by type of braid, internal filler (main tube), view, quality and fitting size. Let us dwell on the most common division based on the form of braid.

On the specified sign, the flexible eyeliner happens:

reinforced
silphon.

The first is a rubber base (high-quality products are made of durable rubber), coated with steel braid. In this case, the hose cover can be made of different materials. For example, galvanized steel and aluminum occupy a leading place among analogs. This is explained by a low price - and only. Such a braid is absolutely short-lived, it practically does not withstand the average water pressure in the plumbing and is very quickly fail. This should not be, because the upper skin of the rubber hose is designed to strengthen it and do not give water to break out.

For quality and durability, the braid of durable steel stainless wire is considered. It provides reliable protection an internal rubber hose. According to manufacturers, the operational period of such supplying reaches ten years and more.

The nylon braid is the reinforced treatment of the plumbing hose, which can even withstand the maximum pressure in the system.

Choosing a reinforced stalling braid, you automatically receive the following advantages:

installation speed;
ecologically clean materials manufacturing;
high strength;
flexibility.

The second look is an elastic stainless steel corrugation. Silphon hoses serve longer and have higher specifications.

There are two modifications of corrugated elements:

with a set length;
with a variable metro.

For the first manufacturers immediately define standard dimensionsStarting from 20 cm and finishing 80 cm. Step in the length of the product is 10 cm. The second has a floating range to which it can be stretched. For example, you can find bellows with a variable length of 150-250 mm, 200-350 mm and others. It is worth considering the fact that the maximum stretching is indicated reference - undesirable to stretch the eyeliner to so much.

On quality, strength and durability is evidenced by the use of bellows for industrial purposes. Very often, this type of lining is used when connecting sprinklers - fire extinguishing ceiling devices. The main nuance is a plumbing system. Sprinkler installation is a whole network of pipes in which water under pressure is constantly. Therefore, the choice of particularly high-quality stamp material becomes how it is impossible.

Among the disadvantages of the bellows flexible liner, it is allocated for noisy work when high pressure In the water supply system. Despite the fact that in modern apartment houses This happens infrequently, some users recommend using it as close as possible in private possessions.

Fittings are usually supplied with flexible liner. Often it is brass fittings or nuts that have various forms and sizes. To properly select the mount, you need to measure the diameters of the pipes in the room where the installation will be made.

Plumbing wiring was previously made of vehicles of pipes, tubes and adapters. But today, thanks to the flexible eyeliner, the possibility of installing devices using water supply in the most small-sized rooms. The angular flexible liner provides installation even in hard-to-reach places. Thanks to the features of its attachment, it can be close to the wall and increase in this way. useful Square premises.

Dimensions

The main parameters of flexible eyeliner are the diameter of the hose and its length. In this case, the caliber is important not only in the tube, but also in fittings. For example, modern flexible liners are produced with a maximum diameter of 1-2 inches. And the most frequently used parameters in 1/2, 3/4 and 3/8.

As for the length of the reinforced or corrugated hose, each manufacturer has its own.In addition, it is practically individual for each individual case. If we consider a stationary eyeliner, then the maximum length has 60 cm. In corrugated sliding models, this indicator can only start from a mark of 500 mm, and finish - within 5000 mm. The latter are extremely rare, mainly on an industrial scale.

Manufacturers: Review and reviews

The most popular today is the flexible liners produced in Italy. They have proven themselves in the construction market, and many users gladly celebrate their advantages.

One of the most popular Italian sampling brands today is Parigi.. According to customer reviews, the products of this brand have high strength. The manufacturer guarantees the service life of reinforced flex cells from 3 to 5 years, the bellows of the same products can hold out more than 7 years. The Italians pay special attention to items: fittings and nuts are made of high-quality nickel and have a service life for more than 10-15 years. Product prices are high, which is about 60% of users consider the main disadvantage.

Mateu.- Spanish manufacturer, who has proven itself as a high-quality manufacturer of the average price segment. In sets of faucets for the kitchen or bathroom, you can very often find flexible liners with a metal braid of this particular company. Also, they produce products of their own brands for large construction hypermarkets in large quantities.

Another feature of the Spanish manufacturer is the production of reinforced eyeliner using PEX hoses. According to professionals, such a kind of hoses has the maximum service life, as they are created from stitched polyethylene. Operation of such a material in some cases reaches 50 years. Another feature of the PEX hose in its versatility: flexible liners with such a base can be used to connect both complex devices (for example, heating systems) and simpler (cold and hot water supply).

Domestic Santechprom also does not stand still. A large number of high-quality, but more affordable products produce such manufacturers like "Giant", "Monolith", "Aquatekhnika". Users mark a large number of pluses in these eyelbs. But still approximately 50% of respondents insist on the inconsistency of some of the technical characteristics specified in the product passport, but in general, they are satisfied with the acquisition.

In order for each item to function correctly and as long as possible, it is necessary to strictly follow the rules for connecting and installing elements. Despite the fact that even a high school student will cope with this process, some specialist advice should be taken into account when installing.

Connection rules

Compounds of water systems are carried out with each other by means of special mounting fasteners. As mentioned earlier, these are fittings and nuts. The hose must be mounted freely, slightly saving, so when the length is selected, it is based on a large figure. As for the fittings directly, they are different diameters (0.5-1.5 inches) and a different form. If a plumbing pipe and liner have different diameters, a special adapter comes to the rescue, which can be easily found in all sanitary shops.

Consider the basic rules for the installation of flexible lining for water.

Before installing, and even better before buying, make a complete inspection of the lugs of the reinforcement (fasteners). Check, whether the gasket is in place, in what state the thread and braid.
After installation, it is necessary to connect the water supply to the system and within 30-40 minutes check the lining operation for the object. If the leakage still appeared, try tightening nuts tighten the nuts. But with this, too, you need to not rearrange, so as not to spoil the mount.
The hose bending is allowed in the ratio of no more than 5-6 diameters of the outer tube.

The slog is very afraid of high temperatures, so try to avoid the operation of the product in unfavorable conditions for it.
Twice a year, it is necessary to check the tightness of the installation and the inspection of the external state of the flexible lining.
In case of lack of hose length, you can purchase a special extension cord. In order to avoid corrosion of the metal due to the electromechanical reaction, it is necessary to use pairs of equal material.
Despite the service life specified by the manufacturer, it is recommended to replace flexible eyeliner at least once every 3-5 years.

Among the prohibitions there are three immutable rules:

do not use in constant flowing mode;
do not install without laying or visible defects;
do not exploit under reduced negative temperature.

The scope of use of flexible supply is quite wide.One of the main rules here will be the feasibility of their use in this particular situation. There are cases when such products have been used to connect fan coils - elements of the air conditioning and ventilation system. Any flexible reinforced or bellophone reinforcement for water has a variety of fasteners. In the language of professionals, they are called: "Mom" - "Mom", "Pope" - "Mom", "Pope" - "Dad". "Mom" here is expressed by a cape nut, and "dad" is a long fitting.

In the process of installing a flexible water supply for water, it is not necessary without recommendations and councils of specialists, especially if the installation is performed by you personally and for the first time.

Deciding on a flexible water supply, you risk, unfortunately, to face the purchase of poor-quality fake.

That this does not happen, here is a list of basic recommendations for the acquisition of a good product.

Buy only in proven outlets and well-known manufacturers.
Reliable products are always equipped with a passport with a description of the technical characteristics (for example, the maximum pressure and temperature in the system that this hose withstands), the term and rules of operation. Quality models Usually have indicated expiration date up to 10 years.
In addition to the accompanying documents, there are special labeling on each product with the indication of the same technical characteristics, a perceptor company, diameter and other things.
All official brands are put on the sanitary market only certified positions.

Because of its design, bellows appliances usually have increased noise formation. But this can be avoided if you purchase such hoses with a special plastic coating.
The best material for precipitated nuts and fittings is a nickel-plated brass, and aluminum or hybrid steel-aluminum components serve three times less - no more than 3 years.
Sometimes in the process of screwing the eyeliner may occur its twisting, unnecessary bending. Such moments should be avoided and closely monitors the condition of the hose. Otherwise, this can lead to early abrasion by the rubber component and its ambulance.
With visual assessment of the quality of flexible eyeliner, pay attention to the braid, which should be homogeneous, without burrs, sticking tails and other drawbacks, and the fittings should be qualitatively crimp.
Rubber gaskets included in the set, usually rarely serve their owner for a long time. Perhaps there is a need to acquire more strong products from silicone or paronite.

How to make it yourself

Folk craftsmen are easily divided by recipes according to the manufacture of flexible liner with a reinforced braid.

The details of one of them include:

stainless steel flexible tube;
fixture for trimming pipes;
roller;
nuts;
rubber or silicone gaskets.

The technology is to cut off the desired piece of the pipe, rolling both of its edges, fix them with a locking ring, ride nuts and install gaskets.

In the process of installing a flexible eyeliner for water there is nothing complicatedbut there is a number of nuances of choice required details. Therefore, carefully pay attention to all the little things before the work of payment for the product so that you do not have to return and buy a new eyeliner.

For the qualifications of flexible water lining, see the following video.

A few years ago, in almost any bathroom, you could see large jets and intricate steel pipes connected to various plumbing. Washbasins and shower cabins connected to them through a variety of couplings and adapters. As a result of this connection, all corners of the bathroom were occupied by massive structures from pipes that regularly failed due to hydraulic vibrations and shocks.

With access to the plumbing market, a new flexible supply "Nut - Naka" managed to solve not only the problem of rapid destruction of the water supply, extinguishing its service until 10-15 years, but also to free the space by expanding the free area of \u200b\u200bsmall bathrooms.

Features and advantages

The flexible system consists of a movable elastic hose, covered on top of a metal braid. Its length can begin with 30 cm and reach 5 m. At the ends of the eyeliner are nuts and fittings with seals from rubber, which are attached to the main pipe and to the plumbing element or home appliances. Color markers are applied to the metal braid, which indicate the scope of the hose. On the hose with red marking should flow exclusively hot water, on the hose with blue marking - exclusively cold water, and the double color indicates the versatility of the product.

You can also meet a strip type yellow color. It is designed to connect and work with gas equipmentBut it is impossible to connect it to the water. Inner surface The elastic hose such a liner is impregnated with special substances, which in no case should fall into drinking water.

Flexible eyeliner almost completely replaced hard steel tubes Due to large number Advantages.

Unlike old massive pipes, thin flexible liners occupy a smaller space and allow you to place sanitary products at a large distance from the main pipe, without climbing the space near the walls and gender.
The flexibility of the hose allows you to move the already connected household appliances And connect it even in the smallest rooms.
The product does not need welding and connects with almost "bare hands". This not only saves money to buy welding machines, but also to connect independently even a newcomer.
Higher, compared to conventional pipes, the reliability of the product prolongs the service life of up to several decades.
Such a flexible tube is more resistant to external damage and inner hydrowards.

Flexible eyeliner, though much better than tough, but has its drawbacks.

The product does not tolerate tension and twisting, they can damage and deform it.
It is forbidden to install a flexible liner next to open fire. The exception is the gas hose in the metal braid, although it is recommended to mount it so that it cannot get to the fire on the stove.
If the water is served simultaneously in several rooms, then the flexible eyeliner starts to vibrate and, as a result, creates a low hum.

Specifications

In the plumbing market, you can meet two different flexible supply categories - adapters and extension cords. Adapters are conventional water supply hoses to shower cabins, sinks or washing machines. Their length rarely exceeds 0.5 m. With the help of an extension connector connected to the adapter, water is summarized to those areas to which the usual hose cannot reach.

The characteristics of the eyeliner and the first and second category are similar and look like this:

the diameters of the external and inner radius of the pipe are 12 and 11.5 mm, respectively;
the nominal pressure is 8 bar, and the maximum reaches 10 bar;
the minimum bending radius is 60 mm;
maximum permissible temperature of 70 degrees;
the work resource is at least 10 years;
the hardness of the rubber hose 75 by Shore;
maximum torque of reinforcement at the ends of the hose 50 nm.

Views

The production of flexible liner is still under development, but there is already a wide range on the market. They are classified by various characteristics, for example, on a braid, by type of fittings or internal filling. The most common of them is the classification of the type of braid.

Reinforced

One of the most sought-after types of flexible lining is the reinforced lodder. It consists of two parts: the inner rubber hose and the outer steel braid. Hoses of different lengths are wrapped with steel solo (blue for cold water, and red for hot), fittings or nuts with rubber seals are attached at the ends.

The maximum operating temperature of this eyeliner is +90 degrees, so it is not used for mounting heating systems. Nevertheless, it is very convenient for connecting to the mixer, washing machine or boiler. Benefits include:

convenience and speed of installation, of all tools are enough of one conformal key;
greater flexibility than other species;
greater durability compared to polypropylene tubesSince the reinforced lining is reinforced with metal.

The disadvantages of the reinforced product include:

fast wear of subtle rubber seals;
fast wear braid with frequent beggars.

It is worth the reinforced product significantly below the bellows supply, but also wears somewhat faster. The average service life is about 2-4 years.

Silphon

The bellows is a steel corrugated pipe up to 2 meters long, which can be stretched and compressed to the required values. At its ends, brass nuts with rubber gaskets can withstand sufficiently high temperatures. Such a metal harmonica can withstand the differences from the minimum temperature in -50, to the maximum in +250 degrees. It is often used to supply water to heating systems and cooling systems, for example, for fan coils or split systems.

The advantages of such a corrugated liner are:

high reliability and durability;
resistance to hydrowards and temperature differences;
this eyeliner does not burn and can be mounted even near open fire;
it is hygienic and completely safe for humans.

Of the minuses can only be distinguished:

high price;
strong noise created by water current on such a pipe.

The service life of the flexible tube can reach 25-30 years, however, it is very expensive. It can be used not only for water supply, but also gas.

From stainless steel

Hoses made of stainless steel are cheaper than bellows, and they serve lon longer reinforced. Their length can begin from 50 cm and reach 1 m. At the ends of the stainless hose, as well as on the reinforced, there are ordinary nuts or fittings. With their help, you can connect the eyeliner both to normal and to the angular adapters. Among its advantages can be noted:

high resistance to corrosion (higher than that of other pipes);
democratic price;
ease of installation;
resistance to fire and sharp temperature differences.

The disadvantage of such an eyeliner is only one - with low quality of rubber gaskets or insufficient tightening of the fixing nut, a similar liner begins to flow in the connection places and quickly comes into disrepair.

Materials and sizes

Flexible submarine different species It may consist of both one material and from a combination of several. The inner elastic hose is made of rubber or rubber.

Rubber hoses are most often used to connect to a toilet or washing machine, as it is impossible to serve drinking water. Rubber has a specific smell that will be transmitted to water coming on it. In addition to the inner hose, the eyeliner is braided from above the reinforcing material that protects the fragile hose from external damage. It can be made of various metals or synthetic materials.

Aluminum

This braid is suitable only for water supply with a temperature not higher than 80 degrees. It is very subject to corrosion and its service life does not exceed 5 years.

Stainless steel

Stainless steel braid increases the lift service life from 5 to 10 years, while the maximum water temperature increases to 95 degrees, and pressure up to 10 atmospheres. One of the varieties of stainless braid is a all-metal pipe called a bellows liner.

Nylon

The nylon braid will last about 10 years and is able to withstand heating to 110 degrees. In addition, its operating pressure is increased to 20 atmospheres, which significantly increases the price of such products.

Zinc

A galvanized wire braid is no longer durable and flexibility, however, the price of it is much less than on other materials.

The main sizes of flexible liner are the length of the hose, internal and external diameters. In this case, the diameter is not only the hose itself, but also the caliber of fittings located along the edges. The diameter of modern hoses rarely exceeds 1-2 inches. Most often on sale you can find eyeliners with diameters 3/8, 3/4 and 1/2 inches.

As regards the length of flexible pipes, it differs significantly depending on the manufacturer. Most often, the ruler begins with products of 500 - 600 mm long, and ends with large industrial pipes reaching 5000 mm.

Purpose

Flexible eyeliner is used almost everywhere, its goal is to connect a plumbing device with tap pipe. With it, it is possible to bring water to the crane located near the kitchen sink or on the sink in the bathroom, you can connect washing and dishwashers and various pumping stations. They serve water into a drain toilet bowl, shower cabin and boiler. They are mounted for water supply to sprinklers (sprinkler system is component Fire extinguishing systems, irrigation heads and pipes, bringing to them water).

In addition to conventional water supply systems, flexible liners are used in a variety of different devices. For example, gas pipelines, technical pipelines or pipes in various cars.

How to choose?

In order to properly select a flexible eyeliner suitable for each specific case, it is necessary to take into account the many nuances:

The braid must be seamlessdepending on which room there will be an installation and operation of the pipe. The nylon pipe can not be mounted near the fire, and the metal indoors with high humidity.
The size should be soSo that the pipe does not stretch when connecting, but also to buy too long products. If the hose length is incorrect, it is either unreliable attached or twisted with free rings, which will quickly destroy the braid on bends.
The hose should not have a sharp rubber or chemical smell.Such a liner is strictly forbidden to use to supply drinking water, it is only suitable for technical needs.

The product should not be too easy- This is a low quality material indicator. The highest quality is the product of stainless steel or with brass fittings, and the most poor-quality - from silumin and zinc. There are hoses with plastic fittings - these are practically disposable products.
Power assignment must match the operating temperature and pressurespecified in the accompanying documentation. Do not connect the hose in the blue braid to the battery or the gas stove - it can lead both small trouble and this emergency situations.
The hose must be well stuffed There should be no defects on the housing. Packaging you need to pick up one-piece and with the corresponding marking.

Italy is a manufacturer, which has long established itself in the construction industry. Products of the company are considered one of the best Italian stoves. Parigi.High prices are due to the reliability and durability of their eyeliner. All fittings are made of high-strength nickel and will serve at least 15 years.

No less popular foreign manufacturer is the company Mateu.from Spain. Products of the average price segment occurs in almost every third apartment. Her a distinctive feature It is the use of rex hoses crosslined from polyethylene. The same storms of this brand can also be used to supply cold water and for mounting the heating system.

Yes, not everywhere metal and even plastic pipes You can replace hoses, but where this replacement is real, an important question arises in front of the homeowner - how to make the right choice?

Advantages of hose

The main feature of flexible eyeliner directly in the flexibility itself. First of all, the hoses are practical in transportation - they can be folded and they will take less space.

As for the installation, the hoses are won not only thanks to the ease of fastener itself, but also the mobility that the connected device can get. For example, you can push the same washing machine if something fell for it. And if the connection was stationary, it would have to hurt the overlapping of communications and dismantle the connection.

Regardless not only installation, but also disassembling hoses. Due to this, it is possible less problematic to carry out repairs or redevelopment of the premises and its networks. Often the hoses have strength similar to non-flax plastic pipes.

Disadvantages of hose

FROM metal structures The hoses, of course, do not compare, but for greater protection, some models are covered with braid. Moreover, there are completely metallic flexible compounds, but they, of course, are not so strong as ordinary static pipes from the metal. The hoses are somewhat more expensive than ordinary pipes, but they are used less, so the overpayment is not so significant. Both warranty and overall life of hoses less than the pipes. However, some modern flexible structures can serve as 20-30 years.

Water supply

Hoses are used to supply water to mixers, toilet bowls, batteries, washing machinesBoiler ... often for this use PVC or Rh-pipes, which some experts rank to the classes of hoses, because flexibility characteristics are not the only feature of the classification. But these products are still more suitable for a common wiring, and it is better to use flexible connections for the immediate lodding systems.

You can find rubber hoses on sale, but their number is very small. The fact is that they have a lot of flaws - expansion at high temperatures and pressure, poor resistance to chemical and mechanical impacts, relative unreliability of fixtures of connector. Therefore, an increasing number of sellers and buyers are focused on more modern designs.

The rubber hose in the metal braid got colossal popularity due to good technical characteristics and comparative cheapness. The core system remains the same rubber hose, but on top it is braided with metal threads with red and blue stripes. Thanks to this refinement, rubber is protected from hydraulic shocks and mechanical damage. Some manufacturers went further and instead of rubber use ethylene propylene rubber with increased density, braided with stainless steel or aluminum. It is worth noting that the steel braid is about two times longer than aluminum.

One end of the hose ends with a metal sleeve with a cape nut joined on the end of the pipe with a thread, the other - the fitting, which is screwed into the connected system. Around the sleeves, the braid together with the hose is crimped with a metal sleeve.

Anti-vibration flexible supply - A little improved hose in the braid. In essence, they are the same, but anti-vibration has a thicker outer diameter. Due to the increase in the walls, such a hose exhibits noises, so indispensable for pumping equipment.

Silphon hosesalso remind a flexible eyeliner in the braid, but all parts of the hose that come into contact with water are made of stainless steel. The hose is made in the form of an annular corrugation (corrugated sleeve). The design sleeves are roasted (radially deformed) on the sleeve and by means of roller welding are welded to the sleeve.

The operating temperature range (from -50 to +250 ° C) allows you to use hoses for almost any communications. In addition, the calf hose is more resistant to mechanical damage. Accordingly, it serves somewhere on a third longer than braided, but it is more expensive.

Hoses are the type of load:

in pressure
in picor suction
in suction (vacuum).

By the manufacturer of the wall:

rubber;
polyvinyl chloride (PVC)
polyurethane
from heat-resistant polyvinyl chloride
silicone
metal.

According to the type of reinforcement:

without reinforcement (tube)
with pvc spiral
with fabric cord
with metal about cord.

Despite the fact that hoses can be used for completely different tasks, their designs combines flexibility and some material similarity. Therefore, experts allocate the main tips that may be useful when carrying out most of the work:

The hose laying place should be easily accessible. Incorrectly in terms of safety and practicality, if the repair you need to partially disassemble the floor or the walls of the walls. In addition, hidden communications are not available for an important service inspection.
In order to avoid inflection, tension or twisting when assembling flexible connections, you must observe the bending radius, on average equal to the s-multiple diameter.
Bending radius can be increased by flexible connections with crankshaft.
If you do not provide a small margin along the length of the hose, then at a pressure, it will be shorter and the construction will be created with an excess voltage.
It is necessary to avoid electrolytic damage to the tips and not connect copper and steel. Steel is joined with steel, brass -s copper.
Metal parts must be protected from condensate, which causes oxidation.
All flexible connections must have metal tips.
It is advisable to use two wrench. It is important that the tip tightening force ensures the desired connection density. To ensure the tightness of the connection, there is no excessive force - it can only damage the structure.
After the end of the installation is checked, whether the hose is not twisted. Mounted systems must be tested for strength, leaving them under load for a while and controlling the strength and tightness of the compounds.
It is forbidden to connect an exposure to open fire, for example soldering lamp. If something is soldered next to or cook, you need to protect the hoses with a thermal screen.
It is important to learn and take into account the shelf life and requirements for the replacement of selected hoses, especially gas. Sometimes the replacement is needed after 10-20 years, but it happens that after 5 years, and then and 2 years. With proper laying of the hose, it should be replaced less than 15 minutes.

Watering

In order to make it easier to choose a suitable hose, first of all you need to decide on the necessary diameter. The most common parameters 1/2 ", 3/4", 5/8 ', 1'.

Next you need to select the length of the hose. Bays are measuring 15.25, 30, 50 m, there are also cutting hoses. The larger the length of the hose, the greater should be its diameter. This is necessary in order to preserve sufficient water pressure in the case of using a sprinkler or spraying installation.

The next no less important factor when choosing a hose is Presence of diagonal reinforcement. It determines the stability of the size, the hose is not deformed under the pressure of the water, it does not go beyond and does not twist. This ensures a long service life.

It is also necessary to pay attention to the limit pressure Water that withstands the hose. It should be higher than the pressure in the feed system (usually indicated in the atmosphere). Such data manufacturer often indicates packaging.

And the last but no less important indicator is the absence of unsafe additives, such as calcium, barium and lead.
