Shandong Seamless Steel Pipe Plant explained: high pressure seamless steel pipe D60*8 Extruded Plastic Strip,Pvc Edge Trim,Gold T Trim,Black T Edge Banding Wuxi Jierui Changkun New Material Technology Co., Ltd , https://www.jrck-plastic.com
DN60*8 refers to the outside diameter and wall thickness, but the special standard medium and high pressure seamless steel pipe outside diameter is not the same depending on the specific implementation of a standard high pressure seamless steel pipe, high pressure boiler pipe is a boiler tube, belongs to the seamless steel pipe category . The manufacturing method is the same as that for seamless pipes, but there are strict requirements for the steel grades used in the manufacture of steel pipes. High-pressure boiler tubes are often used under high temperature and high pressure conditions. The tubes are subject to oxidation and corrosion under the effect of high-temperature flue gas and water vapor. The steel pipe is required to have high endurance strength, high oxidation corrosion resistance, and good organization stability. High-pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, air tubes, and main steam tubes for high-pressure and ultra-high-pressure boilers.
High-pressure seamless steel pipe production method High-pressure seamless steel pipe is a kind of seamless pipe. The manufacturing method is the same as that for seamless pipes, but there are strict requirements for the steel grades used in the manufacture of steel pipes. According to the use of temperature is divided into general boiler tubes and high pressure boiler tubes.
Overview of high-pressure seamless steel tubes (1) Manufacturing methods:
1 The use temperature of high-pressure seamless steel pipes is below 450°C. Domestic pipes are mainly made of hot-rolled or cold drawn tubes of No. 10 and No. 20 carbon steel.
2 High-pressure seamless steel tubes are often used under high temperature and high pressure conditions. The tubes are subject to oxidation and corrosion under the effect of high-temperature flue gas and water vapor. The steel pipe is required to have high endurance strength, high oxidation corrosion resistance, and good organization stability.
(2) Uses:
1 High-pressure seamless steel 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 arched brick tubes.
2 High-pressure seamless steel tubes are mainly used for the production of superheater tubes, reheater tubes, air tubes, and main steam tubes for high-pressure and ultra-high-pressure boilers.
