High pressure boiler tube profile: High-pressure boiler tubes are a kind of boiler tubes and belong to the category of seamless steel tubes. 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 Boiler Tube Overview: High pressure boiler tube specification: 8-1240×1-200mm High-pressure boiler tube manufacturing process: hot-rolled, cold drawn, hot-expanded high-pressure boiler tube standard: GB3087-2008 - China National Standard GB5310 -2008 - China National Standard ASME SA106--U.S. Boiler and Pressure Vessel Code ASME SA210 - U.S. Boiler and Pressure Vessel Code ASME SA213 - U.S. Boiler and Pressure Vessel Code DIN17175 - Federal German industrial standard high pressure boiler tube specification and appearance quality: Specifications and appearance quality: GB5310-95 high pressure boiler tube diameter 22 ~ 530mm, wall thickness 20 ~ 70mm range. Cold-drawn (cold-rolled) tubes have an outer diameter of 10 to 108 mm and a wall thickness of 2.0 to 13.0 mm. High pressure boiler tube weight method: [(Outer Diameter - Wall Thickness) * Wall Thickness] * 0.02466 = kg/meter (weight per meter)
