201 304 316L 904L 2205 2507 polished Cold Drawn Stainless Steel Seamless Pipe
Stainless Steel Seamless Pipe
The stainless steel seamless pipe is a long strip of steel with a hollow section and no seams around it. It is also known as a steel pipe that is resistant to weak corrosive media such as air, steam, water, and chemically etched media such as acid, alkali, and salt. Stainless acid-resistant steel pipe. Manufacturing process of stainless steel seamless pipe:
1. Hot-rolled (extruded seamless steel pipe): round billet heating piercing three-roll skew rolling, continuous rolling or extrusion stripping sizing (or reducing diameter) cooling straightening water pressure test (or flaw detection) marking storage
The raw material for rolling seamless tube is round tube billet. The tube embryo is cut by a cutting machine and the billet with a growth of about 1 meter is sent to the furnace by a conveyor belt for heating. The billet is fed into the furnace and heated at about 1200 degrees Celsius.
2. Cold drawn (rolled) seamless steel pipe: round billet heating piercing beating annealing pickling oiling (copper plating) multi-pass cold drawn (cold rolling) billet tube heat treatment straightening water pressure test marking storage.
