20G high pressure boiler tube implementation standard GB5310-2008 scope of application, is used for manufacturing high pressure and above pressure water tube boiler heating surface with high quality carbon steel, alloy steel and stainless steel seamless steel tube. High pressure boiler seamless steel tube is a kind of boiler tube, because 20G high pressure boiler tube is often used in high temperature and high pressure conditions, the tube under the action of high temperature flue gas and water vapor, oxidation and corrosion will occur. The steel pipe is required to have high durable strength, high oxidation corrosion resistance and good microstructure stability. High pressure boiler tube is mainly used to manufacture high pressure and ultra-high pressure boiler superheater tube, reheater tube, pipe, main steam tube, etc. In the operation of high pressure boiler seamless steel tube, the stipulated water level should be maintained in the bubble, the pressure should not exceed the boiler operating pressure, boiler workers should often monitor the steam pressure gauge. When the boiler pipe is full of water, it should be drained in time to stop co-hydrating and restore the water level. After the furnace is stopped, after the water is long cooled to below 70 degrees, the furnace water can be released, and then the chemical treatment boiler water engase can be used after the net is put out. High pressure boiler seamless steel tube is mainly used to manufacture high pressure and ultra high pressure boiler superheater tube, reheater tube, pipe, main steam pipe, etc. Type boiler tube according to the high temperature performance is divided into general boiler tube and high pressure boiler tube.
