Steel tubes made of a single piece of metal with no seams on the surface are called seamless steel tubes. According to the production method, seamless pipe is divided into hot rolled pipe, cold rolled pipe, cold drawn pipe, extrusion pipe, pipe jacking and so on. According to the section shape, the seamless steel pipe is divided into round and irregular two kinds, irregular pipe has square, oval, triangle, hexagonal, melon seed shape, star shape, with a variety of complex shapes. [1] The maximum diameter is 650mm and the minimum diameter is 0.3mm. Depending on the use, there are thick wall and thin wall tube. Seamless steel pipe is mainly used for petroleum geological drilling pipe, petrochemical cracking pipe, boiler pipe, bearing pipe and automobile, tractor, aviation high-precision structural 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.

Performance index of steel pipe
The mechanical property of steel is an important index to guarantee the final serviceability (mechanical property) of steel, which depends on the chemical composition and heat treatment system of steel. In the steel pipe standard, according to different use requirements, the tensile properties (tensile strength, yield strength or yield point, elongation) and hardness, toughness indicators, as well as user requirements of high, low temperature performance.

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.
