20G boiler tube

　　20G high pressure boiler tubes are, but there are strict requirements for the steel grades used in the manufacture of steel tubes. 20G high pressure boiler tubes are often in high temperature and high pressure conditions when used. The tubes will be oxidized and corroded under the action of high temperature flue gas and steam. The steel pipe is required to have high lasting strength, high anti-oxidation and corrosion performance and good structural stability. High pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, air ducts, main steam tubes, etc. of high-pressure and ultra-high-pressure boilers.

　　20G high pressure boiler tubes are made of steel for boiler pressure components, which are generally used in boilers below 39kg. In order to use under high pressure, the heating surface tubes are often designed to be very thick. 16Mng is widely used in order to reduce thermal resistance and save steel, ensure the safety of steel for high-pressure or high-pressure boilers, and reduce steel consumption. At the same time, there are also special steels with metal and non-metallic materials such as rare earth and magnesium. This will improve the performance of boiler steel, reduce steel consumption and reduce thermal resistance.
