Product Description
We can supply seamless steel pipes in various materials and standards.
Seamless steel pipe is made by perforating the whole circular steel bar, and the steel pipe without weld seam on the surface is called seamless steel tube.
According to the production method, seamless steel tubes can be divided into hot-rolled seamless pipes, cold-rolled steel seamless tubes, cold-drawn steel seamless pipe, extruded steel seamless tube, and seamless steel pipe jacking.
Carbon seamless steel pipes are divided into two types according to the cross-sectional shape: round seamless steel pipe and special-shaped seamless steel tube.
According to different purposes, there are thick-walled seamless steel tubing and thin-walled seamless steel pipes.
According to different materials, it is divided into ordinary carbon structural tubes, low alloy structural tubes, high-quality carbon structural pipes, alloy structural pipe, stainless steel tubes, etc.
Seamless carbon steel pipes are mainly used as petroleum geological drilling pipes, petrochemical cracking pipes, boiler tubes, bearing pipes, and high-precision structural steel pipes for automobiles, tractors, and aviation.
