锅炉管,High pressure boiler tubes are used in high temperature and high pressure conditions. Steel tubes are subject to oxidation and corrosion under the action of high temperature flue gas and water vapor. The steel tube is required to have high lasting strength, high oxidation resistance corrosion performance and good stability.
