Manufacturing process of ASTM A234 WP5 steel pipe fittings:
The process of A234 WP5 pipe fittings manufacturing is called “wrought” which means it is casted or forged.Usually the ASTM A234 WP5 elbows,tees,reducers are made from A335 Gr P5 Seamless steel pipes,the caps are made from plates.
A234 WP5 Pipe fittings is made of A335 Grade P5 Seamless pipes，which is widely used in oil refineries applications.

ASTM A234 WP5 Pipe fittings Heat treatment
All alloy steel fittings (including WP5) must be heat treated according to the specification.
Heat Treatment Type: Normalized and Tempered or Annealed
Detailed Procedure:
-
Normalizing Temperature:
1030 – 1200 °C (1885 – 2190 °F)
→ Air cool. -
Tempering Temperature:
Minimum 675 °C (1250 °F)
→ Hold sufficiently to ensure uniform tempering.
