Seamless steel pipe is a steel pipe that is perforated from a whole round steel and has no welds on the surface. 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.

Carbon steel seamless pipe is a kind of long steel with hollow cross section and no joint around. It has a hollow cross section, a large number of used for conveying fluid pipelines, such as conveying oil, natural gas, gas, water and some solid materials pipelines.
Compared with solid steel such as round steel, carbon steel seamless pipe has the same bending and torsional strength and is light in weight. It is an economic cross-section steel, widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe, automobile drive shaft, bicycle frame and steel scaffolding used in construction, etc.
