ASME SA-192 seamless carbon steel boiler tubes for high-pressure equipment, and is completely equivalent to ASTM A192, which is carbon steel seamless boiler tubes for high-pressure applications. High-pressure boiler tubes are a type of boiler tubes and belong to the category of Seamless Steel Tubes. The manufacturing method is the same as that of seamless high-pressure boiler tubes, but there are strict requirements on the steel grades used to manufacture steel tubes. High pressure boiler tubes are often used in high temperature and high pressure conditions. High-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.
Due to the long-term working of the boiler tube under high temperature and high pressure, the material will undergo creep, the plasticity and toughness will decrease, the original structure will change, and corrosion will occur. Steel pipes used as boilers should have: (1) sufficient permanent strength; (2) sufficient plastic deformation capacity; (3) minimum aging tendency and hot brittleness; (4) high resistance to oxidation, coal ash and natural gas Corrosion, steam and stress corrosion properties at high temperature; (5) Good organizational stability and good process performance.
