FAQ

• What is the difference between high pressure boiler tubes and low and medium pressure boiler tubes?

The differences between high pressure boiler tubes and zhi low and medium pressure boiler tubes are as follows:

• the execution standards is different
• Different use environments

High pressure boiler tubes: the working pressure is generally above 9.8Mpa, and the working temperature is between 450℃ and 650℃ Low and medium pressure boiler tubes: the working pressure is generally not more than 5.88Mpa, and the working temperature is below 450℃

• Different materials Suitable materials for high pressure boiler tubes:

20G, 20MnG, 25MnG, 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, etc. Suitable materials for low and medium pressure boiler tubes: 10#, 20#

• Different prices

The price of high pressure boiler tubes is higher than that of low and medium pressure boiler tubes.

• The difference on materials between fluid pipe and boiler pipe?

The working environment of fluid pipe is relatively peaceful Boiler tubes have low carbon, strict control of harmful elements, no segregation of carbon elements and good welding performance

3.Why should boiler tubes be heat treated?

Stress concentration will occur after bending. Heat treatment is mainly to eliminate stress.
