Bellows hoses for water as a reliable way to connect

The emergence of modern flexible hoses for water connection of domestic appliances, which require central water considerably simplified. Now you do not need to carry out welding work to grow tube - is sufficient to establish a flexible hose. Bellows hoses for water is considered the most modern and safest option. Quality materials used in manufacturing, to ensure long life in different conditions.

Technical characteristics of the main types of flexible podvodok water: which is better

In shops you can watch a large selection of flexible hoses for supply of water from different manufacturers, which differ not only at the price, model, or functionality, but also on the quality of materials used, affecting the service life products.

Important! When choosing flexible hoses need to consider the quality of materials used for their manufacture. Merchants must submit the documents confirming compliance with the flexibles water GOST standards, as well as certificates attesting to the quality of products.

Reliable flexible tubing must be made of aluminum or stainless steel. The price is influenced not only material, but also the presence of additional options. For example, some manufacturers offer a hose equipped with anti-vibration liner, which features a larger diameter section. This reduces noise during the supply of water to a household appliance. To understand how flexible hoses to water the best, should be familiar with the technical characteristics of each type.

Rubber hoses. The main advantages of these models are considered to be low cost and the ability to operate under high pressure. Hoses consist of a frame made of a durable yarn or metal spirals. Rubber used for coating either the outer or the inner side. Main features:

1. The maximum pressure level, which is calculated on rubber reinforced hoses - not more than 10 bar.
2. The temperature of the liquid to be supplied through the hose should be within the range from - 50 to +120 ° C.

Brief sleeves and reinforced PVC hoses: general settings

Hoses made of polyvinyl chloride (so-called PVC), have a high ductility. Additional rigidity PVC sleeves attached reinforcing spiral placed inside the product. Main advantages:

• light weight;
• resistance to chemicals;
• smooth inner and outer surface ribbed, providing ease of installation;
• They are not afraid of direct sunlight;
• operating pressure, which is calculated on the hoses is 15 bar.

The main disadvantage of installing PVC hoses is a small range of temperatures at which permitted use the device - from -20 to +60 ° C, which does not allow to apply this kind of hot flexibles water.

Reinforced hoses, which represents the soft hose with a sleeve which is made of aluminum, stainless or galvanized steel. The most popular domestic manufacturers producing a flexible liner for water, - Elka, which offers products in the performance of the nut-nut with a diameter of 1/2 inch section.

Sometimes, instead of a metal braid nylon used, but generally, these hoses are used in a domestic environment. Technical parameters of the various options of reinforced flexible hoses are shown in the table below:

Type reinforced liner	Parameter
Service life, years	Maximum allowable pressure bar	The maximum temperature at which operation is possible tmax
Galvanized steel and aluminum	No more than three	5	+80
Stainless steel	To 10	10	+95
Nylon	15 and more	Up to 20	110 and above

Bellows hoses for water: Main characteristics

Bellows eyeliner stainless steel water is a corrugated hose, which is used for the production of steel AISI 304 with marks. The sleeves are welded or extruded, but is typically a standard wall thickness, and is 0.3 mm. In the complete set to the hose connectors are the so-called fittings: either the union nut or fitting, covered with nickel or chromium. They are made of materials such as:

• brass;
• steel;
• bronze.

Hoses that use connectors made of brass, characterized by good corrosion resistance, while the product price is acceptable. The service life is typically 5 years, because the brass nuts are welded and fixed on the hose ends by means of soldering. Under the influence of high temperature brazed seam collapses faster.

The best option considered Connectors made from stainless steel, since they can withstand high vibrational loads and thermal expansion. However, the price of a flexible liner for water with stainless steel fittings are significantly higher than the cost of products with brass connectors, although they can be used for much longer - up to 10-15 years.

Do not recommend choosing hoses, fittings which are made of carbon steel, which is resistant to rust and corrosion, and a constant finding leads to their rapid in wet conditions oxidation. Typically, carbon parts need to be replaced every 2-3 years.

Interesting information! Safe fixing tightness and quality of the compounds in the bellows is ensured by the fact that 2-3 corrugated outer ring pass rolling process.

The shopping centers are different sizes of flexible hoses for water supply, which differ not only in length but also the diameter of the internal section of the nuts. The most popular are considered flexible liner for water 1 1/2 inches and 2 and 3/4. If you are using a non-standard flexible hoses for water 3/8, then you need to purchase an additional adapter before installing. The table below shows the size in inches and centimeters:

sectional size, Inches	sectional size, see

The main reasons that made a flexible liner for bellows popular water

The reliability and durability of bellows hose provides water mainly material used for fabrication. steel of high quality, reliable manufacturers that apply different strength. The material is resistant to corrosion. Other technical characteristics bellows hoses for water 1/2 (and other sections):

1. Transfer the impact of corrosive acids and other chemical compounds.
2. They are highly resistant to changes in the pressures within the conduit, and temperatures.
3. Characterized by long service life - 20 years or more.
4. They are used in a wide temperature range from - 40 to +250 ° C, which allows the flexible bellows liner for heating.
5. Operating pressure, which is calculated on the sleeves, is 1.5-3 MPa. This figure depends on the sectional diameter and wall thickness.
6. Are included paronitovye gaskets or copper or fluoropolymer seals.

When the purchase is important to note that the thickness of the gasket must not be less than 2.5 mm, because in operation it is subjected to heavy loads. It is also necessary to know the main feature that allows to distinguish the water hose from the gas. At present different labeling products: for water - blue or red, and the gas - yellow.

Each hose is supplemented with a separate locking ring, providing a snug fit to joints and rabbet a water pipe or the adapter that is used in the case where the diameter of the hose does not coincide with the diameter pipe. Depending on the particular use of all types of hoses, bellows can be divided into 2 main groups:

1. Extra Long sleeves, which are used to sum up the water to the far-located home appliances or plumbing fixtures, such as a dishwasher, sink, shower. Hose length varies from 90 cm to 3.5 m, and the standard set for water flexibles - nozzle-fitting, nut-nut or nut-fitting.
2. Conduit adapters. This group includes a flexible liner for water, the length of which varies from 20 to 100 cm. Used to directly connect the customer to the central water supply.

Main features and advantages of the flexible bellows liner stainless steel water

Bellows hoses for the mixer has gained popularity due to the large number of advantages relative to other models. If the production is used only high-quality metal, the hose is characterized by an increased resistance to sudden slugging as well as to oxygen diffusion, which occurs due to excessive pressure arising inside network.

Other advantages of the device are considered high resistance to fire, ecological safety materials used in production, which allows to maintain the hoses in a domestic environment and in all living areas. Among other options products bellows tube of stainless steel has high wear resistance, ensuring a long service period, which is at least 2 times the life of other species flexible podvodok. Due to the corrugated bellows base is able to preserve and maintain a constant pressure along the entire length of the hose, even in case of strong inflection.

Apart from the fact that the bellows hoses used to connect a water or heating, it is often used when installing air conditioning equipment and fire suppression systems. The product can be used as a device providing vapor outlet during operation of industrial plants that use petroleum products and toxic chemicals.

It is interesting!The large cross section of flexible liner for water (2 1/2 inch or 2) allows the use of the product, even in the food industry, whereby the infeed solids or special fluids. In everyday life such a large diameter often used to divert water from the washing machine.

Despite the fact that the flexible bellows liner of water from stainless steel by a high number of advantages, the products have some disadvantages. The main of them is a lower rate of flexibility in comparison with rubber hoses. In some cases, it causes some problems when installing or requires the use of an additional corner adapter. For example, such a situation may be encountered when connecting a small sink, which is located right next to the main water pipe, when the installation of the corrugated tube considerably complicated.

The main drawback of the bellows liner many believe a high price, which is at least 2 times the cost of analogues of other materials. If we consider that the guaranteed service life of the flexible hose 2 times higher, the high cost due to this easily leveled.

Bellows water hose can be used not only for connecting the water supply, but also for heating equipment. With their help, the radiator is connected to the main heating riser. This advantage is provided by the fact that the products are designed for use with high temperature water, which is unusual for other types of flexible hoses for water.

Major manufacturers flexibles stainless steel water

How to choose a flexible liner for water and other diameters 1/2

Liner should be selected so that the fittings, whether a nut or fittings, formed a reliable connection to connect bubbled devices without additional adapters. To do this, should I buy the product manufacturers that offer standard sizes of flexible hoses for water fittings - 1/2, 3/4 or 1. If you buy a liner 3/8, then connect a hose will be possible only with the help of an adapter.

If you plan to connect to the hot water or the heating system, you must also check the technical characteristics of the products and to ensure that they conform to the temperature of water supplied and designed for high pressure in system. All this information is contained in the passport to the hose. Find out what the water temperature resistant product, you can use the markings:

• blue - a hose only for cold water;
• red - the product is intended for supplying hot water;
• red and blue - the universal hose which can be used to connect the cold and hot water.

Depending on the conditions of use of the bellows is chosen different material, from which the braid is formed. If you plan to use the hose in an environment where there are corrosive chemicals, and there are constantly high humidity, it is better not to acquire options, made of ordinary metal.

Must be approached carefully and to the choice of a flexible liner for water size. Despite the fact that the bellows is designed to double the increase, experts recommend buying a product with a small margin length. If the sleeve will always be in the form of tension, it is not the best way affect the useful life. Other important points that you should pay attention when buying:

1. Flexibility. If the product is well bent, it will be easier to mount. Hoses that are flexible, have a higher quality.
2. The material used for the manufacture of fittings. Preference should be given to the connectors made of non-ferrous metal or a stainless steel, and plays an important role metal thickness: thin aluminum will fail. To prevent electrochemical corrosion, the threaded connection and coupling nuts have to be made of the same alloy.
3. The weight of the finished product. Hose, which has a low weight, most likely was made of silumin - cheap aluminum alloy. Silumin products rot away within a few years.
4. Manufacturer. You should buy the product only to those companies that have been certified in Russia and received permission to sell.
5. Smell. Hose for drinking water, should not differ by the presence of foreign chemical odors.
6. sectional diameter. If you set a flexible liner for water 3/4 rather than 1/2, then the sound of water will be less due to the large outlet.

Important!When purchasing certified products need to check the availability of the technical certificate, which specifies the type of steel, which was used in the production, manufacturing date and expiry date, as well as basic information about the Manufacturer. If the seller can not provide proof of the product is better not to acquire.

Before buying a hose, it is necessary to carry out careful visual inspection of the products for defects and check the quality of the corrugations. It is important that the fittings are securely welded to the hose, and on the surface there were no traces of corrosion and mechanical damage. Undergo mandatory inspection and gasket-sealing, it is necessary that they do not look old or cracked.

Features self-install flexibles and care for her

After installing the hose must be located in a prominent position, free access to it must be ensured. Before you install the product, you should check the integrity of the flutes and attachment, because in the course of transportation or due to improper storage of defects may appear.

Spinning connectors, do not apply excessive force or apply for this gas keys as you can strip the threads or damage the product. It is recommended to tighten the nuts to use a wrench. Other rules to be followed during the installation:

1. Do not twist and strong no flex cable. It should be understood that the stretch hose can be just prior to installation, after the installation of the product to increase the length of the forbidden.
2. After completion of the installation of the hose need to open water and to monitor the connection status for 5-10 minutes. Then, using a light, dry cloth should be checked on a dry dock - when it detects drops need to re-tighten the union nut.

The main problems that can occur during operation, mainly associated with the purchase of low-quality products, at the same time is not always low-quality product has a low price. Therefore it is necessary to pay attention to the appearance of the finished product and quality of joints.

Another problem, which leads to water leakage, considered weak Compression Fittings. To avoid buying dubious quality, hoses should be selected only at certified locations and only from vendors who can provide documents for the goods.

High quality products can be used at temperatures above 100 ° C, which allows their use as a liner for heating. Through qualitative materials used in manufacturing hoses are resistant not only to temperature but also to changes in pressure. Even in the event of a sudden large supply of water under pressure, whereby possible water hammer, stainless steel bellows guarantee preservation membrane integrity.

Bellows flexible hoses for water connection is considered to be the modern version of plumbing and appliances that require access to the central water supply.
