Standard GB/T 5310 Round Stainless Welded Carbon Steel Pipe Hairline Mirror

GB/T5310 high-pressure seamless steel pipe: mainly used for manufacturing high-pressure steam boiler pipelines and other high-quality carbon structural materials.

Steel, alloy structural steel, and stainless heat-resistant steel seamless steel pipes are used in high-temperature and high-pressure conditions. Pipes are subjected to oxidation and corrosion under high-temperature flue gas and steam. Therefore, the steel pipes are required to have high durability, high oxidation resistance, and good structural stability. Commonly used steel grades include: high-quality carbon structural steel grades 20G, 20MnG, 25MnG; alloy structural steel grades 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB; and stainless heat-resistant steel commonly used 1Cr18Ni9, 1Cr18Ni11Nb. In addition to ensuring chemical composition and mechanical properties, finished steel pipes must undergo hydrostatic tests, expansion, and flattening tests. The pipes are delivered in a heat-treated state. Furthermore, there are certain requirements for the microstructure, grain size, and decarburization layer of the finished steel pipes.

Seamless steel pipes for geological drilling and petroleum drilling control are used to explore the structure of underground strata, groundwater, petroleum, natural gas, and mineral resources by drilling wells.

GB5310 high-pressure seamless steel pipe materials: 20G, 20MnG, 25MnG, 16Mn, 15MoG, 20MoG, 15CrMo, 15CrMoG, 12Cr1MoV, 12Cr1MoVG, Cr5Mo, 10CrMo910

GB5310 high-pressure seamless steel pipe (GB5310-12008) specifications: ∮16-824×2-65

Calculation formula for the weight of GB5310 high-pressure seamless steel pipe: [(outer diameter - wall thickness) * wall thickness] * 0.02466 = kg/m (weight per meter)
