ASTM A335 Alloy Steel Seamless Pipe P1 P5 P9 P11 P12 P22 P91 & T5 T9 T11 T22 T91 factory
Description
A335 P22 pipe is a kind of chrome moly pipes (ASME S/A335, Chrome-Moly) listed in ASTM A335, which 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. Chrome Moly Pipes are popular in P-Grades P5, P9, P11, P22, P91 and P92. The most common use of grades P11, P22 and P91 is in the powder industry and petrochemical plants, Grades P5 and P9 are commonly used in refineries.
