General boiler tube temperature:

①General boiler tube temperature below 350 ℃, the domestic pipe is mainly 10 steel, 20 steel carbon steel hot-rolled pipe or cold-drawn pipe manufacturing.

② High-pressure boiler tube is often used in high temperature and high pressure conditions, the tube in the high temperature smoke and water vapor, oxidation and corrosion will occur. Requirements for steel pipe with high enduring strength, high oxidation corrosion resistance, and good organizational stability.

Commonly used national standard high-pressure boiler steel pipe steel and its maximum allowable temperature, high-pressure boiler tube working conditions are very harsh, to be at high pressure and high temperature, in high-speed gas flow, water flow, gas scouring and corrosion can be safe to work for 10 to 20 years, or even longer. High pressure boiler tube of different steel working temperature is also different, in general, the alloy material boiler tube than ordinary material carbon steel boiler tube working temperature is a little higher. The following are commonly used national standard high-pressure boiler tube steel and its parameters:
