SA335 Grade P11, ASTM A335 Grade P11 Alloy Steel Seamless Pipes is a high temperature service ferritic alloy steel pipes, ASTM A335 P11 Material. The specification covers pipes that could be used in fluid transmission at high temperatures in applications such as oil refineries, nuclear and thermal power plants and in petrochemical industries. There are different grades and the Grade P11 has a specific composition. The composition includes chromium and molybdenum as this is a chrome moly pipes specification. There are carbon, manganese, phosphorous, sulfur and silicon in smaller quantities in this material as well. The presence of chromium and molybdenum make these pipes corrosion resistant and resistant to wear and tear.
ASTM A335 Grade P11 Alloy Steel Seamless Pipes
SA335 P11 Material
The ASTM A335 P11 Pipes, ASTM A335 Grade P11 pipes have the minimum yield strength of 205MPa and a minimum tensile strength of 415MPa. There are different types of pipes endings such as the coupling, plain end and beveled ends. The pipes range from 3/8inches to 30 inches in outside diameter. The SA335 P11 Material, Alloy Steel P11 Chrome moly pipes can come in seamless hot rolled or cold drawn conditions. There are tests to provide certification such as EN 10216-2, UNS K11597, GOST 550-75 and NBR 5603 to confirm that these pipes are according to standards. Their pressure capacities and wall thicknesses vary with schedules. The ASTM A335 Gr P11 Pipes, P11 Steel Pipes can have varying wall thicknesses up to 250mm and schedules from 20 through XXS and heavier.
