DIN17155 1.0425/A515.Cr60 Pressure vessel seamless steel pipe production plant
DIN17155 1.0425/A515.Cr60 Pressure vessel seamless steel pipe is a kind of boiler pipe, belonging to the seamless steel pipe category. The manufacturing method is the same as seamless pipe, but there are strict requirements for the steel used in the manufacture of steel pipes. High-pressure boiler tubes are often in high temperature and high pressure conditions when used, and 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 durable strength, high oxidation corrosion resistance, and good organizational stability. High pressure boiler tube is mainly used to manufacture superheater tube, reheater tube, airway, main steam tube, etc., of high pressure and super high pressure boiler.
Heating surface pipe for low and medium pressure boiler (working pressure is generally not more than 5.88Mpa, working temperature below 450℃); For high pressure boilers (working pressure is generally above 9.8Mpa, working temperature between 450℃ ~ 650℃) heating surface pipe, economizer, superheater, reheater, petrochemical industry pipe, etc.
According to the composition of the material classification can be divided into EN 10028-2 high-pressure boiler tube, BS 1501 high-pressure boiler tube, ASTM/ASME A285-387 high-pressure boiler tube.
