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 A234 WP5 caps are made from plates.
