I have a PQR of thickness 22 that require pwht and impact test so from where i can choose the soaking time?
From sec 8 ucs 56 or sec 9?
If yes how? And how much is the soaking time?
From construction codes, ASME BVPC Section VIII Div. 1 UCS 56.
Min. 60 minutes for P-No. 1, 2, 3, 4; Other P-number given in the Table UCS-56-2 to 11.
I dont know time range of 300 minutes, can you re-verify it in the chart no. JP-PQR-337?
