Boiler tubes are a type of seamless tubes. The manufacturing method is the same as that of the seamless pipe, but there are strict requirements on the steel type used in the manufacture of the steel pipe. According to the use temperature, it is divided into two types: general boiler tube and high pressure boiler tube.Core Hardness Control of Carburized Gears High-pressure boiler tubes are often under high temperature and high pressure conditions when used, and the tubes will be oxidized and corroded under the action of high-temperature flue gas and water vapor. Steel pipes are required to have high durable strength, high resistance to oxidation and corrosion, and good structural stability.Vacuum sintering of Al2O3 ceramic products use: ①General boiler tubes are mainly used to manufacture water wall tubes, boiling water tubes, superheated steam tubes, superheated steam tubes for locomotive boilers, large and small smoke tubes and arch brick tubes, etc.ZNC SERIES DIE SINKER EDM MACHINE ②High-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.MEDIUM WIRE CUTTING EDM MACHINE
