Dear Ali,

             Flush type clean out using for drain the inside liquid completely. Because this elevation will be the same bottom plate elevation. but the nozzles all having some height from the bottom.

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
