High quality Non-secondary steel pipe 500 diameter sch40/sch80/sch100/xs/xxs

Our factory was built about 20 years more, and specially produce seamless carbon steel pipes, line pipes, alloy pipes, casing pipes and couplings. The largest diameter is 500mm.

  Seamless steel pipe is hollow section, a large number of used for conveying fluid pipe, such as oil, natural gas, coal gas, water and some solid materials, such as pipelines.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.

500 diameter steel pipe is widely used in tap water, natural gas, petroleum, chemical industry, medicine, communication, electric power, ocean engineering, etc
