SMLS high pressure boiler pipes

PIC-(SMLS high pressure boiler pipes)

　　High-pressure boiler pipe is a kind of boiler tube,belong to the category of the seamless steel pipes. The method of manufacturing the same and seamless, but the manufacture of steel pipe used, there are strict requirements. High-pressure boiler tubes often in high temperature and high pressure conditions, the use of the tube under the effect of high temperature flue gas and water vapor, oxidation and corrosion will occur. Requirements durable steel with high strength, high resistance to oxidation corrosion, and have good organizational stability. High-pressure boiler tube is mainly used to manufacture high pressure and ultra-high pressure boiler superheater tubes, reheater tubes, windpipe, the main steam pipe.
