Product Description

304 grade stainless steel pipe ss304 stainless steel square pipe tube




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




Surface resistance less than 1000m;Wear protection;Scalable;Excellent chemical resistance;

Good alkali-resistant metal and acid energy;Strong toughness;Flame retardant.
