Stainless steel pipe according to the production mode is divided into seamless pipe and welded pipe two
categories, seamless steel pipe can be divided into hot rolled pipe, cold rolled pipe, cold drawn pipe and
extrusion pipe, cold drawn, cold rolling is the secondary processing of steel pipe;The welded pipe is
divided into straight seam welded pipe and spiral welded pipe.

Stainless steel pipe is a kind of hollow long round steel, mainly widely used in petroleum, chemical,
medical,food, light industry, machinery and instruments and other industrial conveying pipes and mechanical
components.In addition, in the same bending, torsional strength, light weight, so also widely used in the
manufacture of mechanical parts and engineering structures.Also commonly used as furniture and kitchen
utensils.

Stainless steel seamless tube production process
A.Round steel preparation ⇒ B.Heating ⇒ C.Hot rolled perforation ⇒ D.Cutting head ⇒ E.Pickling ⇒
F.Grinding ⇒ G.Lubrication ⇒ H.Cold rolling ⇒ I.Degreasing ⇒ J.Solution heat treatment
⇒ K.Straightening ⇒ L.Pipe cutting ⇒ M.Pickling ⇒ N.Finished product inspection.
Every process will be checked by responsible QC which insures every product's quality.
