Gas hose to a gas stove: how to make the right choice

Earlier in the gasified gas cooker homes connected directly to the pipeline via a steel pipe. The method was considered safe, but caused some inconvenience. The main disadvantage of rigid installation is considered impossible plate changes in a comfortable position to organize the working area properly. Modern flexible gas hose to a gas stove is not considered less secure, but allows you to set the cooking surface where it will be convenient.

What is the hose of the gas pipe: The main requirements for the product

In appearance hose to connect the gas stove is very similar to the water. The main difference is the presence of a gas device yellow or white markings that must be visible. In addition, the flexible connection for gas cookers are made of special material. Another feature is the presence of paronitovye pads - a special ring, which is used to seal the flange connection. It is the presence of gasket ensures safety of the products.

Important!If you wonder what kind of hose is needed for the gas stove, the main component here is the availability of appropriate labeling and a certificate issued by Rostekhnadzor Russia. This document certifies that the product meets the safety requirements. In addition, the hose must be accompanied by a passport, which indicates the date of manufacture.

Purchase high-quality and certified products ensure the safe use of gas, but the purchase of a hose of questionable quality without proper documents can lead to tragedy. Other mandatory requirements for a flexible gas hose to the plate:

1. The product must be integrated, without additional couplings, extenders or compounds.
2. It is necessary that the flexible hoses had special coating resistant to hot liquids and high temperatures.
3. The hose should not be subject to corrosion.
4. product parameters required to match the characteristics of the gas used.
5. gas hose service life for gas stoves should not be less than 10 years.

Unacceptable interconnect several arms - it is better to acquire hose for gas cookers, the length of which will correspond to the distance between the gas pipe and the cooking surface. Maximum length of the gas hose to connect the plates according to European standards is 2 meters, although the longest certified products is considered to be a seven-meter hose. If you view the relevant Russian GOST standards, we can see that they are no recommendations relating to the length of the gas hose. In any case should not be installed too far away from the plate of the gas pipe.

Now the market offers a wide variety of options for mobile connections for gas. The materials used in production, also differ in specifications affecting the service life. Therefore, to understand what should be the hose to a gas stove in a particular situation, it is necessary to take into account the location and characteristics of cooking surface. The main types of hoses are:

• oxygen;
• rubber reinforced;
• rubberized;
• reinforced PVC hose;
• bellows.

Gas hose for gas cookers: main types of products

in Soviet times, oxygen hoses are mainly used because of the fact that there were no alternatives. For the production of this type of hose is used a special thread Cord and additional pictures, which is applied to protect the threads, it is a rubber composition.

In modern time the oxygen hose often used for welding or for transporting gas mixtures, such as acetylene, butane, and propane. Sometimes hose is used to connect the gas cylinder as a fuel source, for which security is set away from the plate. Permissible temperature gradation at which the product can be used - from +70 to -35 degrees Celsius. Positive aspects of application of oxygen hoses:

• resistant to 20 atm .;
• easy to install;
• do not conduct electricity;
• are low cost;
• fit different diameters of pipes.

In modern apartments is not recommended to use oxygen hoses to connect the plates, because, First, products are not very attractive black color, and secondly, they are not allowed to repaint. After contact with oily solution is heated and the hose surface integrity may be lost, which would lead to gas leakage. The cost varies from 70 to 90 rubles. per square meter.

Rubber sleeve cloth refers to simple and affordable options. The hose is a rubber base, reinforced strong textile filament. With the additional components are added to the rubber mixture, the term of service of the gas hose to the plate is about 5 years, that is still not enough for high-quality products.

Another disadvantage of the application considered the fact that after a while may cause cracks on the surface, which can cause gas leakage. The product is characterized by low operating temperature range, which is only -10 to +50 ° C. On the positive properties include the simplicity of use, ease of installation, the ability to bend well and excellent electrical insulation.

Important!Rubber hoses for gas cookers with a fabric braid must have a yellow label that distinguishes them from products for water. Often recommended to connect the hob to the gas cylinder. Experts advise to replace the hose every 2-3 years.

Other types of gas hoses for gas cookers: size, price

Gas rubber hose in a metal sheath having an inner portion made of a polymeric material, which top layer is covered with vulcanized rubber. Outside braided hoses special steel filaments, creating a so-called reinforced layer.

The main disadvantage of the use of hoses is considered high ability began to pass electricity, and exposure inner polymeric material destruction, which may be overlooked because of the presence of upper layers. If the stove is not in use at this time recommend to cover the gas hose, which will increase its durability. Price for the finished product is 60 cm long starts from 140 rubles.

Applying this type of connection is further necessary to mount the dielectric inserts, which are installed in the joint between the hose and the gas pipe. The presence of the insulator will prevent a gas stove and hose itself from the effects of stray current, which can cause a fire.

The advantages of using a rubber-reinforced hose:

• reasonable price;
• easy installation;
• operation in a large temperature range: -35 to +50 ° C;
• a wide range of lengths and diameters.

Reinforced PVC hose is considered to be more modern than the above options due to the fact that the characteristics of the material does not allow the product to conduct electrical current. In addition, PVC is not destroyed as easily as rubber. Strength provides additional hose having two PVC layers. Inside the sleeve is a black material, while the upper layer is often characterized by a yellow color. It is used for any type of liner gas mixture: acetylene, propane and butane.

Gas PVC hose for gas cookers designed for operating pressures up to 0.63 MPa, and the temperature at which can operate the gas ranges from -20 to +90 ° C, which is a significant advantage. Another positive aspect of the use of PVC is considered a large scatter size, the maximum length of the gas hose for gas cookers - 5 meters, while the minimum - 0.4 m For the manufacture of fittings used galvanized steel, and the dielectric properties are provided by the presence paronitovye. gaskets. Other advantages of the product:

• It is not destroyed on contact with the hot plate;
• reasonable price, the price per square meter product starts from 170 rubles;
• is not subject to deterioration by contact with hot oil droplets;
• suitable for use in conditions of high loads;
• long service life: minimum - 12 years, maximum - 20 years.

Bellows gas hose: the best for gas cookers

If you ask a specialist, what should be the hose for gas cooker, most likely, he will offer to purchase to install it bellows option. This type of hose is considered the most reliable connection of the hob to the central gas supply. In addition to gas stoves, it is used for connecting the speakers and gas-fired boilers used for individual heating. Bellows - a corrugated elastic sheath which protects the inner layer from mechanical and other types of damage.

Great demand for bellows hoses due to high device performance and reliability. Products can easily tolerate a high pressure, which is created by the gas flow in the pipe. Convenience is provided by two connecting fittings, designed for connection to a gas pipe and directly to the instrument. All components of the hose are made from high-end stainless steel that guarantees maximum durability.

Useful advice!For a more secure connection when connecting the hose further uses a special gasket from plastic or soft metal.

The price of gas hose for this type of gas stove is much higher than the cost of other options products, but the duration of the operation for at least 10 years longer than the life of the rest devices. Thus, the minimum time during which you can safely use a bellows hose - 25 years, although some companies offer 30 year warranty. The final price is usually influenced by the manufacturer and the size of the product.

About how much is the gas hose to a gas stove (depending on performance) can be found in this table:

The main advantages and disadvantages of using bellows hoses

Simple models of bellows hose provided in the form of corrugated products, which differ by the presence of circular cross-section. If we choose a more expensive option, it further will be present to protect the metallic sleeve or a polymer coating. A modernized version of the flexible hose has a built thermofilter valve which is at the critical temperature increase stops gas flow independently. Of course, this option will affect and how much it costs sleeve, but the losses that can be obtained in the case of gas leakage, will be much higher. Other advantages of the bellows hose:

• easy to bend and stretch;
• can withstand loads of up to 6 atm .;
• It is operated in a large temperature range from -50 to +200 ° C;
• They are made of quality materials that meet all EU standards;
• meet the technical requirements of the household use;
• the maximum possible service life - up to 30 years from the date of installation;
• withstand the impact of electric current to 1.5 kW;
• large variety of length hoses for connecting a gas cooker - from 0.4 to 5 m;
• compatible with most types of gas equipment and various accessories;
• a coating that protects the base of the hose from the effects of various household chemicals used for cleaning and disinfection of kitchen.

Additional safety hose provides polymeric electrically insulating layer that protects not only against mechanical exposure, but also by high-frequency currents which are generated by some appliances, such as microwave. Due to the strength of the hose manufacturers guarantee the integrity of the connection even with natural abnormalities such as earthquake resistance of the building when disturbed.

For relative disadvantages include only the price that is several times the cost of similar products from other groups. However, the presence of a large number of positive characteristics, which include a significant period of operation, this lack of overlap.

Useful advice!When installing the stove or hob with electric ignition built-in function, experts recommend between tap the gas supply hose and bellows for greater safety guarantees to install an optional dielectric insert.

Gas hoses for gas cookers: Which is better, the main selection rules

The main rule when choosing a gas hose - to purchase the product in a certified shop. If the seller can not provide the quality certificate and does not give any guarantee to buy the product in such a place is not worth it. Usually in retail outlets available in a large variety of gas hose sizes for gas cookers. It is important to have completed all the measurements and buy the product the desired length, because the splice two products is not recommended with each other.

To reduce the risk of rupture of eyeliner, do not recommend to choose such a length that after installation hose will be in constant tension, as this may adversely affect the useful life products. The maximum gas hose length for plates in a flat should not exceed 2-2.5 meters, although there are various options for sizes, including 4 and 5 meters. Additionally, you need to make sure that the product is not only tensioned during installation, but not much slack. Only properly selected according to the length of the hose connection ensures the safety and proper operation.
