Not so long ago, gas stoves were connected toTrunks only through steel pipes. Now the situation is different: everywhere use more convenient flexible podvodku. However, please note that incorrect hose selection and unprofessional installation can lead to a serious accident.
Modern hoses for gas supply differThe fact that their connection to the highway does not cause any particular difficulties. However, such "simplicity" may entail gas leaks, and even accidents, up to the explosion. And the decisive role here is played not only by the professional level of the person preparing the connection, much depends on the variety of the hose itself and its compliance with specific conditions.
Types of gas hoses (hoses)
The cheapest option is rubber hoses. These products are somewhat thicker than water feeders, but they do not have any protection from mechanical influences, there are practically no sharp temperature changes, and the service life of such sleeves usually does not exceed 5 years. The main advantages are softness, elasticity and price. The gas hose in the braid is distinguished by the presence of a special core made of polymer materials. Steel is used for braiding. Such a product intended for gas transportation can be distinguished by yellow stripes on the braid (sometimes solid color) or woven threads of the same color (on the "water" sleeves the strips are blue, red).
Despite the fact that the braided hoses are consideredReliable products, in a number of countries in Europe they are prohibited, preference is given to another modification - bellows metal hoses. Such hoses are protected by a braided stainless steel or polymer coating. Some models even have a built-in valve that prevents the gas flow from entering when the temperature rises above a preset level.
How to choose a gas hose
Pay attention to the diameter: Usually it is standard and is 10 mm, otherwise just not enough gas for the oven and all 4 hotplates. In addition to the type of hose, it is worth taking a closer look at the dielectric insert. This is an important detail that protects the gas stove from possible penetration of the so-called. Wandering currents that may appear as a result of poor grounding or failure, and also, for example, if the insulator is faulty at the entrance of the gas pipeline to the apartment building.
Accumulation of the electrical potential canLead to the heating of the metal braid and, as a result, the melting of the rubber part of the hose. An insert made of a dielectric material and connected between a hose and a gas pipe, prevents the passage of wandering currents. Another danger that lies in wait for the buyer of the gas hose is the possibility of acquiring a fake. Therefore, you should ask the seller for the appropriate certificate.
