Seamless pipe for high pressure boiler
Seamless pipe for high pressure boiler is a kind of boiler tubes and belongs to seamless steel pipe category. Manufacturing methods is the same as seamless pipe, but stringent requirements for manufacture of steel pipes used in the steel. High-pressure boiler seamless pipe, often in conditions of high temperature and high pressure pipe, the effect of high temperature flue gas and water vapor, oxidation and corrosion. Steel pipe with high rupture strength, high resistance to oxidative 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.
2.general boiler tube temperature below 450 ℃, the domestic pipe on the 10th, the 20th of carbon structural steel hot-rolled pipe or cold drawn tube manufacturing.
