Dear Ali,
All flush type connections we need to PWHT which is contact with bottom and shell plate connections that as shown in
API 650 figure 5-12.
This all requirements having in API 650 para 5.7.4 states which condition we need to do PWHT. Because we are not only
doing PWHT for flush type clean out fittings, even material group, thickness restriction, thickened insert plate also doing PWHT. I have attached that page for your reference.
Please feed back to me,
Regards
