The seamless steel pipe is made of perforated whole round steel, and the steel pipe
without weld seam on the surface is called seamless steel pipe.
According to the production method, seamless steel pipes can be
divided into hot-rolled seamless steel pipes, cold-rolled seamless
steel pipes, cold-drawn seamless steel pipes, extruded seamless
steel pipes, and pipe jacking. According to the cross-sectional
shape, the seamless steel pipe is divided into two types: round and
special-shaped. The maximum diameter is 900mm and the minimum
diameter is 4mm. According to different uses, there are
thick-walled seamless steel pipes and thin-walled seamless steel
pipes. Seamless steel pipes are mainly used as petroleum geological
drilling pipes, cracking pipes for petrochemical industries, boiler
pipes, bearing pipes and high-precision structural steel pipes for
automobiles, tractors and aviation.
