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 ASTM A335 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.
