The high-pressure boiler tube is a type of boiler tube, which belongs to the seamless steel tube category. The manufacturing method of du is the same as that of seamless pipes, but it has strict requirements on the steel grades used to manufacture steel pipes. High-pressure boiler tubes are often in high-temperature and high-pressure conditions during use. The tubes will oxidize and corrode under the action of high-temperature flue gas and water vapor. The steel pipe is required to have high endurance strength, high resistance to oxidation and corrosion, and good organizational stability. High-pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, gas guide tubes, main steam tubes, etc. of high-pressure and ultra-high-pressure boilers.
High-pressure boiler seamless steel tubes include: 20G high-pressure boiler tubes, 12Cr1MoVG high-pressure boiler tubes, 15CrMoG high-pressure boiler tubes, GB/T5310 high-pressure boiler tubes, 3087 low and medium-pressure boiler tubes, 40Cr high-pressure boiler tubes, 1Cr5Mo high-pressure boiler tubes, 42CrMo high-pressure boiler tubes.
