High pressure pipe 8
Production method of 20G high pressure boiler tube :
① Generally, the operating temperature of boiler tubes is below 450 ° C. Domestic tubes are mainly made of hot-rolled or cold-drawn tubes of No. 10 and No. 20 carbon steel.
② High-pressure boiler tubes are often in high-temperature and high-pressure conditions when they are used. The tubes will oxidize and corrode under the effects of high-temperature smoke and water vapor. Steel pipes are required to have high durability strength, high resistance to oxidation and corrosion, and excellent arrangement stability.
