2 High-pressure seamless steel tubes are often used under high temperature and high pressure conditions. The tubes are subject to oxidation and corrosion under the effect of high-temperature flue gas and water vapor. The steel pipe is required to have high endurance strength, high oxidation corrosion resistance, and good organization stability.
use
