high-pressure boiler tube Complete specifications - Complete models
20G high pressure boiler tube is a kind of boiler tube, which belongs to the category of seamless steel pipe. The manufacturing method is the same as that of seamless pipes, but there are strict requirements on the steel grades used to manufacture steel pipes. 20G high pressure boiler tubes are often used in high temperature and high pressure conditions, and the tubes will be oxidized and corroded under the action of high temperature flue gas and water vapor. The steel pipe is required to have high lasting strength, high oxidation corrosion resistance, 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.
20G high-pressure boiler tubes use steel for boiler pressure components, which are generally used in boilers below 39 kg. In order to use under higher pressure, the heating surface tubes are often designed to be very thick. In order to reduce thermal resistance and save steel, to ensure the safety of steel for higher or high pressure boilers, and to reduce the amount of steel used, 16MnG is commonly used. At the same time, there are also special steels with added rare earth, magnesium and other metals and non-metallic materials. This will improve the performance of boiler steel, reduce steel consumption, and reduce thermal resistance.
