SUS 201 202 304 316 Stainless Steel Square Hollow Pipe Tube/Ss Tube Square/ Welded Pipe For Building Materials
Product Description:
Stainless steel square tube is a kind of hollow long steel, which is widely used as pipeline for transporting fluids, such as oil, natural gas, water, gas, steam, etc. In addition, when the bending and torsional strength are the same, the weight is lighter, so It is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used to produce various conventional weapons, barrels, shells, etc.
Production process:
Stainless steel square tube (seamless tube) a. Round steel
preparation; b. heating; c. Hot rolling perforation; d. Cut the
head; e. Pickling; f. Grinding; g. Lubrication; h. Cold-rolled
processing; i. Degreasing; j. Solution heat treatment; k.
Straightening; l. Cut pipe; m. Pickling; n. Product testing.
