Latest News:

High Pressure and Temperature Thick Wall High Alloy Seamless Steel Pipe is a seamless tube. The manufacturing method is the same as that of the seamless pipe, but it has strict requirements for the steel used in making the steel pipe. According to the use of high and low temperature is divided into general boiler tubes and high pressure boiler tube two.

① For the low pressure boiler (working pressure is generally not more than 5.88Mpa, the working temperature below 450 ℃) heating surface pipe; for high pressure boiler (working pressure is generally above 9.8Mpa, the working temperature between 450 ℃ ~ 650 ℃ ) Of the heating surface of the tube, economizer, superheater, reheater, petrochemical industry, and so on

② high-pressure seamless steel pipe is often used in high temperature and high pressure conditions, the tube in the role of high temperature flue gas and water vapor, oxidation and corrosion. Requiring steel pipe with high durability, high oxidation resistance, and good organizational stability.

High temperature alloy pipe in the 600 ~ 1200 ℃ high temperature can withstand a certain stress and has the ability to resist oxidation or corrosion resistance of the alloy.

The biggest advantage of the thick wall alloy seamless steel pipe is that it can be 100% recycled, in line with environmental protection, energy saving, resource conservation strategy, national policy to encourage the expansion of thick-walled alloy pipe applications.
