RE: [MW:16418] QW407.2 (ASME Sec. IX)

Not correct - for ferritic materials, the temperature referred to
actually the range of temperature as defined in QW-407.1(a), the holding
time of the PQR is only required to be at least 80% of the required
production time.

Stainless and nickel based are governed by QW-407(b).

I recommend that anyone interested in these provisions of Section IX
review the Code Interpretations that have been published for these two
paragraphs.

Dear Friend,
Nice to meet you. According to ASME Sec 9, QW 407.2 it
is clearly mentioned that the PWHT Soaking temp and time which you had
implemented during procedure qualification has to be essentially
equivalent to your production joint.
Hope it will be clear to you.

Thanks & Best Regards,
