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.
