Factory source Erw Steel Pipe - Precision seamless steel Pipe Cold Drawn Hot Rolled Tube – Lu

Introduction

Precision seamless steel Pipe/tube is a kind of high-precision steel pipe material processed by cold drawing or hot rolling. Because the inner and outer walls of precision steel pipe have no oxide layer, bear high pressure and no leakage, high precision, high smoothness, cold bending without deformation, expansion It is mainly used for the production of pneumatic or hydraulic components, such as cylinders or oil cylinders, which can be seamless pipes or welded pipes. The chemical composition of precision steel pipes includes carbon C, silicon Si, manganese Mn. , Sulfur, Phosphorus P, Chromium Cr. Compared with solid steels such as round steel, seamless steel pipes are lighter in flexural and torsional strength when the bending and torsion strength is the same. It is a kind of economical cross-section steel, which is widely used in the manufacture of structural parts and machinery. Components.
