Product Description
astm a554 25mm 3 stainless steel pipe 316 tube duplex pipe
Stainless steel pipes are divided into ordinary carbon steel pipes, high-quality carbon structural steel pipes, alloy structural pipes, alloy steel pipes, bearing steel pipes, stainless steel pipes, and bimetal composite pipes, plating and coating pipes to save precious metals and meet special requirements. . There are many types of stainless steel pipes, different uses, different technical requirements, and different production methods. The currently produced steel pipes have an outer diameter range of 0.1-4500mm and a wall thickness range of 0.01-250mm. In order to distinguish its characteristics, steel pipes are usually classified as follows.
ways to produce：
Stainless steel pipes are divided into seamless pipes and welded pipes according to the production method. Seamless steel pipes can be divided into hot-rolled pipes, cold-rolled pipes, cold-drawn pipes, and extruded pipes. Cold-drawn and cold-rolled are the secondary types of steel pipes. Processing; welded pipes are divided into straight seam welded pipes and spiral welded pipes.
Section shape：
Stainless steel pipes can be divided into round pipes and special-shaped pipes according to the cross-sectional shape. Special-shaped tubes include rectangular tubes, rhombus tubes, oval tubes, hexagonal tubes, octagonal tubes, and various asymmetrical cross-section tubes. Special-shaped tubes are widely used in various structural parts, tools and mechanical parts. Compared with round pipes, special-shaped pipes generally have larger moments of inertia and section modulus, and have greater resistance to bending and torsion, which can greatly reduce structural weight and save steel.
