More recently, gas stoves were connected exclusively with steel pipes. Now for this use a flexible eyeliner. And with the recent adoption of the new GOST, it is recommended to use a braided gas hose. The same document recommends using the most resistant to mechanical damage and gas pressure bellows gas hose.
However, with the advent of hoses, accidents with explosions have become more frequent. This is due to the fact that the connection process is quite simple, and they began to do the installation themselves. Without special skills, the “masters” do not tighten the connections tightly enough, do not replace leaky pipes in time. It happens that the hose begins to melt from elevated temperature or braid, which is heated by stray currents. In addition, the gas hose is hidden in the wall or under the floor screed, and therefore they don’t notice when it wears out and starts leaking gas.
At the same time, this does not mean at all that the hoses are completely unsuitable forgas transportation. On the contrary, they are suitable, but when installing them, you must be as careful and attentive as possible. And it is better to entrust the work to a qualified specialist.
Which hoses are most commonly used today to transport gas?
Rubber gas hose - this option is the easiest and cheapest. Although it is much thicker than a water supply, it is minimally protected from temperature changes and mechanical stress. Until recently, braided rubber sleeves have been popular. They differ from sewer hoses in the core of the structure. Most often, it is made of polymeric materials, and the braid is made of steel. In some countries, the use of rubber hoses is prohibited by law.
A more practical and safer option is a bellows gas hose. Simpler versions of such a hose are presented in the form of a corrugated sleeve, and more modernized models are equipped with thermal protection valves. The latter model is much more expensive, but it is able to shut off the gas supply if the room temperature rises above the permissible value. Therefore, bellows hoses with dielectric properties are in greater demand than those without insulation.
But this does not mean that gas rubber and rubber-fabric hoses will cease to be used instantly. Currently, GOSTs are more advisory in nature than a mandatory requirement for implementation. Fortunately, most municipal servicesreact to such recommendations, and therefore agitate the population to replace the gas hose in their apartment with a bellows hose.
At its core, all bellows hoses are noteworthy because they are practical for gas supply. Since the gas and water hoses are similar in appearance, each of the inlets is marked accordingly. Therefore, you should carefully study the places of their application and features. Remember that the inner diameter of the gas hose must be at least one centimeter, otherwise the gas distributed during the supply will not be enough to operate several burners and the oven.
