Steel Pipe

Steel Pipe Introduction

Steel Pipe not only used for conveying fluid and solid, heat exchange, manufacturing machinery parts and container.but also is a kind of economy steel.With steel pipe manufacturing space truss structures, pillar and mechanical support, can reduce light weight, saving metal 20 ~ 40%.and It can realize mechanization of factory construction. With steel pipe manufacturing highway Bridges not only can save steel, simplify construction, and can greatly reduce the area of the coating layer, save investment and maintenance costs.so Any other types of steel cannot completely replace steel pipe, steel tube can replace part of the profile and bar.Chinacoal05
Steel Pipe Classification :seamless steel pipe and welded steel pipe（Seamed Pipe ）.Cross section can be divided into the circular tube shape and special-shaped tube.Steel tube is widely used, but there are some square, rectangle, semicircle, hexagonal, equilateral triangle, octagon, circle, circle of China and other special-shaped steel tube in the party.
