The seamless steel tube has a hollow section, which is used as a
pipeline for conveying fluids, such as pipes for oil, gas, gas,
water and certain solid materials.Compared to the steel pipe and
round steel solid steel bending torsional strength phase at the same time, the weight is lighter, is a kind
of economic cross section steel, widely used in the manufacture of
structural and mechanical parts, such as petroleum drill pipe, auto
transmission shaft, bicycle frame and construction of steel
scaffolding is used with steel pipe manufacturing annular parts,
such as can improve material utilization, simplifying the
manufacturing process, material saving and processing time, has been widely used to make steel pipe
