Gas pipe is a kind of special pipeline used to transport combustible gas, its material, characteristics and installation and use of the way to ensure the safety and reliability of gas supply is crucial. The following is a detailed introduction to gas pipes:

Gas pipes are made of a variety of materials, common ones include the following:

Steel pipe:

Seamless steel pipe: processed from high-quality carbon steel or low alloy steel by hot rolling, hot expansion or cold drawing, has the advantages of high pressure, safety and reliability, but the cost is higher, the connection process is complicated. It is suitable for the transportation of medium pressure and sub-high pressure natural gas.
Galvanized steel pipe: the outer surface of the steel pipe is zinc plated by hot dip galvanizing method, which is widely used in low-pressure branch pipe and indoor open pipe. Welding, threaded connection, flange connection and other connection methods can be used.
Copper pipe:

With corrosion resistance, beautiful, light weight and other advantages, but expensive. Suitable for the transportation of non-corrosive fluids, including indoor natural gas piping.
Thin-walled stainless steel pipe:

With corrosion resistance, beautiful appearance, light weight and other advantages, suitable for medium and low pressure fluid transportation. The use of certain wall thickness and connection requirements, and the need to prevent external damage to the protective measures.
