The boiler and chemical pipe, especially high pressure boiler pipe is our advantage. High-pressure boiler tubes are often in high-temperature and high-pressure conditions when they are used. High-pressure boiler tubes are mainly used to make superheater tubes, reheater tubes, air ducts, and main steam tubes for high-pressure and ultra-high-pressure boilers. High-pressure seamless steel pipes are often in high temperature and high pressure conditions when used, and the pipes will be oxidized and corroded under the action of high-temperature flue gas and water vapor. The steel pipe is required to have high enduring strength, high oxidation and corrosion resistance, and good organizational stability. In China, its main grade include 20G、20MnG、25MnG(carbon steel); 15MoG、20MoG、12CrMoG、15CrMoG、12Cr2MoG、12CrMoVG、12Cr3MoVSiTiB(alloy structure steel) an so on
