Tests & Inspection of Alloy Steel Pipes - Gr. P11, P22 & P91 Pipes • Chemical Composition Analysis Test With 100% PMI and One tube from each heat by Direct Reading Spectrometer • Visual Test and Endoscope Test for Surface Quality Test

A335/SA335 P91 is a ferritic alloy steel that has very high strength properties, which do not deteriorate with time, and are creep resistant. It is also called 9 Cr 1 Mo steel, or chrome moly pipe, based on its composition. Compared to its predecessors, the T22 or P22 grade, grade P91 exhibits high strength, enduring temperatures up to 600 °C.
