Re: [MW:23747] MT before or after PWHT?

Thank you for the answers,

I agree with your answer that commonly MT is done after PWHT.

But in some condition MT shall be done before PWHT,

Still looking for this condition? In which CODE

 

Thanks,

code does not say before or after for sec 8 construction, but it is good  engineering practice to MT before and after for P1 materials. As far as B31.1 power piping u have to do NDE after PWHT for materials P3,4,5,15E
