Seamless Steel Pipe

Description

Seamless steel pipes have different uses in various industries.We have carbon steel pipes,seamless steel pipes of various materials and standards, with high product quality and considerate service. We look forward to your cooperation.

Product Description

Seamless steel pipes are made by perforating a whole round steel bar. Steel pipes with no welds on the surface are called seamless steel pipes.
According to different materials, they are divided into ordinary carbon structural pipes, low alloy structural pipes, high-quality carbon structural pipes, alloy structural pipes, stainless steel pipes, etc.
According to the production method, seamless steel pipes can be divided into hot-rolled seamless steel pipes, cold-rolled steel seamless pipes, cold-drawn steel seamless pipes, extruded steel seamless pipes, seamless steel pipe jacking, etc.
Carbon seamless steel pipes are divided into two types according to their cross-sectional shapes: circular seamless steel pipes and special-shaped seamless steel pipes.
According to different uses, there are thick-walled seamless steel pipes and thin-walled seamless steel pipes.
Seamless carbon steel pipes are mainly used as petroleum geological drilling pipes, petrochemical cracking pipes, boiler pipes, bearing pipes, and high-precision structural steel pipes for automobiles, tractors, and aviation.
