ASTM A335 P11 Pipe




ASTM A335 P11 Pipes is a chromium molybdenum alloy made pipes. It is used in the high temperature services. It is corrosion resistant, strong and ductile. Steel India Co. is a manufacturer of different grades of the chromium molybdenum alloy made pipes. We are also one of the leading P11 Pipe suppliers and stockiest. We supply these products to a large customer base over a range of industries. The main industries that use these products are the oil and gas industry, the power generation industry and the petrochemical industries.

As we are one of the leading SA335 P11 Pipes suppliers we manufacture and supply the pipes from different material grades as well. There are different pressure grades in the SA335 material and the SA335 P11 Material is specific in that it could be applied to most high pressure and high temperature services. There are seamless pipes and welded pipes in this range and they are used in different requirements. The SA335 Grade P11 Seamless Pipes is dimensionally accurate and could be used in precision applications whereas the welded pipes are stronger and have high wear and tear properties.
