Alloy Material Hot Rolled Steel Tube Medium Pressure Boiler Application
Chrome Moly Pipe has become a standard in the power generation industry and the petrochemical industry, not only because of its tensile strength, corrosion resistance and high-temperature strength, but also because of its cost-effectiveness. Grades P-11, P-22 – P-91 & P-92 are prevalent grades for the power industry, while P-5 & P-9 are the grades utilized in major refinery processing.
1. Standards
ASME SA106 —— American Boiler and Pressure Vessel norms
ASME SA333 —— American Boiler and Pressure Vessel norms
ASME SA335 —— American Boiler and Pressure Vessel norms
DIN17175 —— German industry standards
