High Pressure Alloy Steel Seamless Tubes ASTM A335 Standard Boiler Application

 

The high pressure pipe is always used in high pressure boilers (which the operating pressure is over 9.8Mpa, the operating temperature is between 450℃ and 650℃) as the heating surface pipe, and economizer, superheater, reheater and petrochemical industry, etc.

 

 

The A335 pipes are generally called chrome moly pipe as they have a high level of Chromium and Molybdenum presence in it. While Molybdenum increases the overall strength, resistance, elasticity, hardenability and overall quality, moly ensures that the material is more resistant to softening, restrains the growth of grains and lessens the chances of embrittlement. It is the single additive that is responsible for the increase in high temperature resistance and it also improves the corrosion resistance to steel.
