Professional Manufacturer Stainless Steel 304 304L 904L Seamless
Tube
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.
