Our factory was built about 20 years more, and specially produce seamless carbon steel pipes, line pipes, alloy pipes, casing pipes and couplings. 

carbon seamless carbon steel pip 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.

1. Construction are: more underground pipelines and extraction of groundwater, hot water boiler used when building, etc.
2. Mechanical processing, bearing sleeve, processing machinery spare parts, etc.
3. Electrical class: gas pipeline, water power fluid.
4. Wind farms anti-static tube, etc.
