Description

Seamless Steel Pipe

Feature:

  • 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.

① The main production process of hot-rolled seamless steel pipe (main inspection process):
Tube blank preparation and inspection → tube blank heating → perforation → tube rolling → waste tube reheating → diameter determination (reduction) → heat treatment → finished tube straightening → finishing → inspection (non-destructive, physical and chemical, Taiwan inspection) → storage

② The main production process of cold-rolled (drawn) seamless steel pipe
Billet preparation → pickling lubrication → cold rolling (drawing) → heat treatment → straightening → finishing→inspection
