Seamless steel pipe for boiler (GB/T5310-2018) is a high-quality carbon steel, alloy steel and stainless heat-resistant steel seamless steel pipe used for manufacturing the heating surface of water tube boilers with high pressure and above. Seamless steel tubes for boilers: these boiler tubes often work under high temperature and high pressure, and the tubes will undergo oxidation and corrosion under the action of high temperature flue gas and water steam, so the steel tubes are required to have high durable strength, high oxidation resistance, and good organizational stability, and the steel numbers are: high-quality carbon structural steel numbers are 20G, 20MnG, 25MnG; Alloy structural steel No. 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, etc. Rust heat-resistant steel commonly used 1Cr18Ni9, 1Cr18Ni11Nb high-pressure boiler tubes in addition to ensuring chemical composition and mechanical properties, to do hydraulic test one by one, to do flaring, flattening test. Steel pipes are delivered in heat-treated condition.
