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. 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.
