Heat Treatment for A234 WP91 pipe fittings
Pipe fittings of ASTM A234 alloy steel, after forming at an elevated temperature, shall be cooled to a temperature. below the critical range under suitable conditions to prevent injurious defects caused by too rapid cooling, but in no case more rapidly than the cooling rate in still air.
Grade WP91 shall be normalized at 1900 °F [1040 °C] minimum, and 1975 °F [1080 °C] maximum, and tempered in the temperature range of 1350 °F [730 °C] to 1470 °F [800 °C] as a final heat treatment.
Inspection and test for A234 WP91 pipe fittings
Except for dimensional inspection and visual examination, the inspection & tests that shall be selectively performed on ASTM A234 alloy steel pipe fittings include: liquid penetration test, magnetic particle examination, ultrasonic test, nondestructive electromagnetic(eddy current) test.hardness testng
