Seamless Steel Pipe

Seamless pipe made of a single piece of metal with no seams on the surface is called a seamless steel pipe. According to the production method, the seamless pipe is divided into a hot rolled pipe, a cold rolled pipe, a cold drawn pipe, an extruded pipe, a top pipe, and the like. According to the shape of the section, the seamless steel pipe is divided into two types: a circular shape and an irregular shape, and the shaped pipe has a square shape, an elliptical shape and the like. The maximum diameter is 650mm and the minimum diameter is 0.3mm. Seamless steel pipe is mainly used as petroleum geological drilling pipe, cracking pipe for petrochemical industry, boiler pipe, bearing pipe and high-precision structural steel pipe for automobile, tractor and aviation.

How to choose the right ERW pipe for industrial application?

ERW pipe (Electric Resistance Welded pipe) is a commonly used welded steel pipe produced by forming hot-rolled steel coils through a forming machine. The edges of the steel strip are heated and fused using the high-frequency current’s skin and proximity effects, followed by pressure welding through extrusion rollers. Unlike traditional welded pipes, ERW steel pipes achieve weld joints by melting the base material itself, resulting in superior mechanical strength and performance.
