Description

Introduction:

301 Stainless Steel Pipe is a hollow strip steel,Because the cross section is square,we call square pipe.A large number of pipeline used for conveying fluid,such as oil, natural gas, water, gas, steam, etc.In addition,when the bending and torsional strength phase at the same time, lighter weight,So it is widely used in the manufacture of machinery parts and engineering structures.Also commonly used for the production of various kinds of conventional weapons, barrel, shells, rail vehicles, belt conveyors, bolts and nuts etc.
