Parameter 

Seamless steel pipe is a round, square and rectangular steel with a hollow section and no joints around it. Seamless steel pipes are made of steel ingots or solid tube blanks through perforation to make capillaries, which are then hot-rolled, cold-rolled or cold-drawn. The seamless steel pipe has a hollow section and is widely used as a pipeline for conveying fluid. Compared with solid steel such as round steel, the steel pipe has a lighter weight when the bending and torsional strength is the same. It is an economical section steel and is widely used in the manufacture of structures. parts and mechanical parts, such as oil drill pipes, automobile transmission shafts, bicycle frames, and steel scaffolding used in construction.
