We Are The Factory: Leading Producer Of Carbon Steel Pipes For Fluids, Boilers, Petroleum, And Fertilizer Industries

Carbon steel seamless steel pipe / fluid pipe / high, low and medium pressure boiler pipe / petroleum cracking pipe / fertilizer pipe

Carbon steel seamless pipe is a kind of long steel pipe. Steel pipe has hollow section, which is widely used to transport fluid, such as oil, natural gas, water and some solid materials. For the fluid transportation with pressure requirements, in addition to ensuring the strength and rigidity that meet the corresponding requirements, it is also required to ensure the tightness, that is, the hydraulic test shall be carried out one by one before leaving the factory.

The medium transported by fluid pipeline is often flammable, explosive, toxic, temperature and pressure medium. The carbon content of carbon steel pipe for petroleum products, oil and gas and public medium with design pressure less than 10MPa is between 0.25% and 0.60%, such as 35 and 45 steel.; The carbon content of high carbon steel pipe is more than 0.60%. In general, the steel pipe of GB / t8163 (A53 / A106) standard is suitable for oil, oil and gas and public medium with design temperature lower than 350 ℃ and pressure lower than 10.0MPa. When the design temperature exceeds 350 ℃ or pressure higher than 10.0MPa, GB / t9948 (A53 / A106 / a335-p2) or gb6479 (A105 / a335-p2 / P22) standard should be selected, GB3087 and gb5310 (a335-p2 / P22) standards are specially set for boiler steel pipes.

The pipe used for fluid transportation has hollow section, which is widely used for transporting oil, natural gas, gas, water and some solid materials. The special pipe for chemical fertilizer is mainly used to manufacture the superheater pipe, reheater pipe, gas pipe and main steam pipe of high pressure and ultra-high pressure boiler. Petroleum cracking pipe is widely used in manufacturing structural and mechanical parts, such as petroleum drill pipe, automobile transmission shaft, bicycle frame and steel scaffold used in construction.
