in addition to above one may consider PWHT requirements if anything applicable as per the design and client spec, if PWHT applicable one may consider additional PQR's or based on the construction code exemption recommendations PQR's Can be avoided by following pre-heat requirements of the construction code.

Appreciate efforts and initiative from ENG.Ahmed.

Just to share. 2 PQR's 6mm & 23mm is sufficient.

There is an ASME Interpretation stating PQR qualified on 6mm and higher thickness qualifies in the range from 16mm.  Someone please share the Interpretation.

Thanks & Regards
