The types of alloy steel covered by the ASTM A335 – ASME SA335 specification are designed with a “P” prefix, from P5 to P92. Grades P11/P22 and P91/92 are typically found in power stations, whereas grade P5 and P9 are more common for application in the petrochemical industry. Grades P9, P91 are, in the list, the more expensive

Alloy Steel pipe are heat treated to achieve mechanical properties as per the desired alloying element. Below are some of the types of heat treatment.
Normalize Quench and Tempering.
Quench and Tempering.
Normalizing & Hardening.
Transverse/longitudinal: tension and flattening, hardness, bend tests- for material which has been heat-treated in batch furnaces, these tests shall be made on the 5% of the pipes from each heat lot number. For smaller lots, one pipe at a minimum has to be tested.
ASTM A335 Gr. P91 shall have a hardness of 250 HB / 265 HV (25 HRC).
Hydro testing: shall be applied to every length of pipe.
The non-destructive electric test is optional.Gaining client pleasure is our company’s aim without end.
