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.
Attribute
