Increase in soaking time

[kumar sumit]

Dear sir

              In Pwht if soaking time period is increase(I.e- 15-20minute) at that time it is accepted or not. If accepted then how. If not accepted then also explain. Because I also search in sec IX but I cannot find.

                      Please explain. 

I thankful to you.

The question is generic.

To answer the query , you may refer below 

For production weld PWHT, construction codes like  ASME SEC I PW 39 . ASME sec VIII DIV 1 UCS 56 are referred.

The holding time at the specified temperature range is followed  as a Minimum from respective Tables in the Codes  .

15 - 20 minutes more than minimum specified is acceptable and no issue is envisaged
