Chrome Moly Pipes (ASME S/A335, Chrome-Moly) are well known as “boiler pipe”, 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.
We stock a full range of the following A335 Chrome Moly Pipe grade.
