Flexible gas hoses for connecting the stove appeared in our country not so long ago. The innovation came from abroad and quickly gained popularity due to the ease of installation and operation. Before the advent of flexible hoses, the structure was fixedly fixed, and there was no question of moving the plate to the side or moving it to a more convenient place. With the advent of flexible hoses, the situation has fundamentally changed. Their varieties and selection criteria will be discussed in the framework of the article.
Overview of flexible hoses for gas stoves
Today, for the most part, it is applied Three types of materials for making flexible gas hoses:
1) Rubber braided from fabric. One of the cheapest materials, which, nevertheless, has a rather good resource of longevity - the product can be used for up to 10 years.
Benefits products:
- ability to isolate electric current;
- cheapness;
- elasticity;
- ease of installation.
Along with the benefits, there are a couple disadvantages:
- low temperature range of operation - from -10 to + 50 degrees;
- relative softness and low mechanical strength of the material.
2) Reinforced rubber with metal braid. A similar material, only with a polymer inner part, is used for plumbing systems. In order to distinguish which system the hose is designed for, it is marked accordingly. Gas, for example, is marked in yellow, for water - blue and red, depending on the application. The material is vulcanized and reinforced with special thread rubber.
Benefits:
- relatively low price;
- good mechanical strength;
- ease of installation;
- the presence of a wide range of products.
TO disadvantages a narrow range of operating temperatures can be attributed.
3) Bellows hose. Its main difference is that it has a corrugated metal braid that provides reliable protection of the inner layer. It is the most reliable of the options given in the article.
Benefits:
- large temperature range of operation: from -50 to + 200 degrees;
- flexibility, despite the presence of a reliable braid;
- mechanical strength and pressure resistance - withstands up to 6 atmospheres;
- resistance to corrosion;
- the presence of a polymer electrically insulating layer;
- product service life is 25 years or more.
Only flaw this type of product - high cost, five times higher than analogues of other materials.
Expert opinion, which gas hose is better
If the budget allows, the decision is clearly in favor of a bellows gas hose. Further, in descending order, there are items made of reinforced rubber in a metal braid and rubber in a fabric braid.
Important!
Some products have a number of installation requirements. For gas boilers, for example, one of the prerequisites is the supply of a bellows gas hose with a dielectric sleeve.
How to choose a gas hose to connect the stove
To purchase a product of good quality, It is worth adhering to the following rules:
- buy hoses and fittings in specialized stores, purchase certified goods;
- avoid products made in China, because despite the availability of certificates, the quality of the product leaves much to be desired;
- pay attention to the presence of appropriate yellow markings on products;
- upon purchase, check the availability of all components, gaskets, nuts, fittings, thread integrity and the absence of visible mechanical damage.
By following these simple rules, you can protect yourself from buying products of inadequate quality.
