What is the implementation standard of stainless steel corrugated gas pipe?

With the acceleration of urbanization in China, the proportion of urban residents using pipeline gas is also increasing. Gas pipes exploded everywhere because of pipeline problems. Therefore, domestic gas pipelines must use high-quality gas pipelines. 304 stainless steel bellows is a good choice, safe and durable. Let's take a look at the implementation standard of stainless steel bellows first! 1.304 is the stainless steel gas pipe safe?

In order to prevent accidents such as fire caused by gas leakage and improve the quality and safety performance of gas pipeline facilities, it is the most effective way to correctly select gas pipeline construction materials.

Rubber pipes commonly used in gas pipelines in the past will corrode the inner wall for a long time, which is inconvenient to maintain and seriously affects the construction quality. 304 stainless steel gas bellows is widely used in domestic gas pipelines because of its strong corrosion resistance, high hardness and long service life.

304 stainless steel gas pipe refers to the gas pipe made of 304 stainless steel, which is corrugated by hydraulic process and covered with a PVC protective layer. The advantages of 304 stainless steel gas pipe mainly include:

1, anti-aging: rubber will become brittle, hard and broken under natural conditions, while stainless steel has much stronger anti-aging ability.

2, high temperature resistance: the hose is not high temperature resistant, and it will soften and catch fire when it is baked by flame. The stainless steel pipe body of stainless steel bellows can withstand high temperature.

3. Anti-dropping: Stainless steel corrugated hoses are generally connected by threads to prevent accidental dropping.

4. Corrosion resistance: the rubber hose is made of organic material, which is not resistant to oil, while the stainless steel corrugated hose is made of 304 stainless steel, which can block the corrosion of many common corrosive liquids, and the coated PVC protective layer also has certain flame retardant and anti-corrosion effects.

5. Long service life: the service life of rubber hose is 2 years, while the service life of stainless steel wave gas pipe is generally more than 10 years, which is durable.

6. Convenient installation: The stainless steel corrugated pipe is elastic because of its dense and deep corrugations, and can be bent at will, so the installation is simple and quick. Because of the elbow, it can be kept parallel to the pot and is not easy to bend.

So in general, stainless steel gas pipe is a kind of safe and durable high-quality gas pipe, and it is also one of the domestic gas pipes recommended by gas companies.

Second, what is the implementation standard of stainless steel corrugated gas pipe?

In 20 10, China promulgated "Stainless Steel Corrugated Hoses and Fittings for Gas Transmission" (GB/T26002-20 10), which stipulated the product classification, model, requirements, test methods, inspection rules, marking, packaging, transportation and storage of stainless steel corrugated hoses and fittings for gas transmission, and was applicable to the nominal size DN/

In addition, the industry standard of stainless steel gas pipeline is Stainless Steel Corrugated Hose for Internal Connection in gas appliance (CJ/T 197-20 10) proposed by the Institute of Standards and Specifications of the Ministry of Housing and Urban-Rural Development, which stipulates the product classification, specification and model preparation, requirements, test methods, inspection rules, marking, packaging, transportation and storage of stainless steel corrugated hose for internal connection in gas appliance. It is suitable for the connection of gas pipelines, such as gas cookers, gas water heaters, gas meters, etc., which are fixedly installed with the nominal size DN not greater than N32 and the nominal pressure PN not greater than 0.0 1MPa.
