Seamless steel pipe is widely used

- Jan 17, 2019-

Seamless steel tubes are used in a wide range of applications. The general-purpose seamless steel pipe is rolled from ordinary carbon structural steel, low-alloy structural steel or alloy structural steel, and has the largest output, and is mainly used as a pipe or structural component for conveying fluid. .2, according to the use of three types of supply: a, according to chemical composition and mechanical properties; b, according to mechanical properties; c, according to water pressure test supply. Steel pipes supplied in categories a and b, if used to withstand liquid pressure, are also subjected to hydrostatic testing. 3. Special-purpose seamless pipes include boiler seamless pipes, chemical power, geological seamless steel pipes and petroleum seamless pipes.

Seamless steel tubes have hollow sections and are used in large quantities as pipes for transporting fluids, such as pipes for transporting petroleum, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, the steel pipe has a lighter weight when it has the same bending and torsional strength, and is an economical section steel.

Widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automotive drive shafts, bicycle frames and steel scaffolding used in construction, such as steel scaffolding, to create ring-shaped parts, which can improve material utilization, simplify manufacturing processes, save materials and processing. In working hours, steel pipes have been widely used for manufacturing.
