Product Description

Product Description

Seamless steel pipe is made of the whole round steel, and the steel pipe with no weld on the surface is called seamless steel pipe. According to different production methods and purposes, there are thick wall seamless steel pipes and thin wall seamless steel pipes. Seamless steel pipes are mainly used for petroleum geological drilling pipes, petrochemical cracking pipes, boiler pipes, bearing pipes and high-precision structural steel pipes for automobiles, tractors and aviation. Seamless steel pipes can also be divided into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold-drawn seamless steel pipes and extruded seamless steel pipes.
