Stainless Steel Square Pipe-Luoyang Huien Metal Products Co., Ltd.

Product Introduction

Stainless steel square tube is a hollow strip of steel, because the cross-section is square so called square tube. A large number of pipelines used to transport fluids, such as oil, natural gas, water, gas, steam, etc., in addition, in bending, torsional strength at the same time, light weight, so it is also widely used in the manufacture of mechanical parts and engineering structures.
