ASTM A335 Pipe P5 P9 P11 P12 P22 P91 P92


 

Chrome Moly pipe has become a standard in the power generation industry and the petro-chemical industry, not only because of its tensile strength, corrosion resistance and high-temperature strength, but also for 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 major refinery processing grades utilized.
