For Manufacture wall panel,economizer, re-heater, super-heater and steam pipeline of boilders.
1.Generally, the temperature of boiler tubes is below 350 C. Domestic tubes are mainly made of 10 and 20 carbon-bonded steel hot-rolled tubes or cold-drawn tubes.
2.High pressure boiler tubes are often used under high temperature and high pressure conditions. The tubes are used in high temperature flue gas and water vapor.When used, oxidation and corrosion will occur. Steel pipe is required to have high durable strength, high anti-oxidation and corrosion resistance, and good structural stability.
