Stainless steel pipe is a kind of hollow long round steel, which is widely used in petroleum, chemical, medical, food, light industry, mechanical instruments and other industrial pipelines and mechanical structural parts. In addition, when the bending and torsion strength are the same, the weight is lighter, so stainless steel pipe is also widely used in manufacturing mechanical parts and engineering structures. It is also used to produce all kinds of conventional weapons, barrels, shells, etc.
Production process of stainless steel seamless pipe:
Round steel preparation --- heating --- hot rolling piercing --- cutting head --- pickling --- grinding --- lubrication --- cold rolling --- degreasing --- solution heat treatment --- straightening --- pipe cutting --- pickling --- finished product inspection.
Production process of stainless steel welded pipe:
Raw material - slitting - welding pipe making - repairing end - polishing - Inspection (spray printing) - Packaging - delivery (warehousing) (decorative welded pipe)
Raw materials - slitting - welding pipe making - heat treatment - correction - straightening - end repair - Pickling - hydrostatic test - Inspection (spray printing) - Packaging - delivery (warehousing) (pipe for welded pipe industry piping)
