High pressure boiler tube is mainly used to manufacture high-pressure boiler,super heater tubes, reheater tubes, windpipe, the main steam pipe, etc.,, It often works in high temperature and high pressure circumstance.Under the American standard ASME and GB5310-95 and processed by EBT + LF / VD smelting process, the hydraulic press forging, machining (sets of boring) molding. Production supercritical, ultra supercritical high pressure and a series of large-diameter thick-walled seamless pipe, and get industry production license, five boiler plants and sold to domestic power plants and other manufacturers. 钢号 SA-106C 12G1MOVG P12 P22 P91 P92 规格 外径 φ219~φ800mm 壁厚 50~150mm

The main process is EBT+LF/VD melting + press forging + machining and boring + heat treatment. The specification is that outside diameter ≤ ￠1200mm, wall thickness ≥ 50mm, length ≥ 5000mm.The main material is SA106C, 12CrlMoVG, P12, P22, P91, P92 and etc.
