Application requirements of stainless steel tubes

Application requirements of stainless steel tubes

The main use of stainless steel is the exhaust system, accounting for more than 1/2 of the total automobile stainless steel consumption, 80% for ferritic stainless steel. The exhaust gas produced by the automobile engine is discharged from the muffler through the exhaust gas intake pipe, front pipe, hose, converter and center pipe. Exhaust system commonly used steel 409L, 436L and so on. Automobile mufflers mainly use stainless steel welded pipe. It is estimated that stainless steel pipes used in automobiles account for about 1.5% of the total downstream use of stainless steel pipes, and the use ratio of stainless steel seamless pipes and welded pipes is about 2:1.

Connection mode of stainless steel pipe

Connection mode of stainless steel pipe

Stainless steel pipe connection modes are various, the common types of pipe fittings are compression type, compression type, loose type, push type, push thread type, socket welding type, loose type flange connection, welding type and welding and traditional connection combination of derived series connection. These connection modes, according to their different principles, its scope of application is also different, but most of them are convenient to install, firm and reliable. The sealing ring or gasket material used for connection is mostly made of silicone rubber, nitrile rubber and EPthree rubber which meet the requirements of national standards, so as to avoid the worries of users.
