I have a socket welded flange that will have a pipe welded to it. Which do I use for the flange calc, loose or integral type flange?

Loose type flanges are attached by fillet welds.
Integral flanges have FJP groove welds.
Optional flanges have PJP groove welds.

RE: BPVC VIII-1 Appendix 2
Based on my research I think you may have confused the terminology of the weld types
PJP = Partial Joint Penetration,
The other joint type is CJP Complete Joint Penetration (not FJP, Full Joint Penetration)
From: www.lbyd.com/.../Welding-Symbols-and-Presentation-...
The Complete Joint Penetration (CJP) groove weld is a groove weld that extends completely through the thickness of components joined. The primary purpose for the use of the CJP groove welds is to transmit the full load-carrying capacity of the structural components they join.
The Partial Joint Penetration (PJP) groove weld is a groove weld that does not extend completely through the thickness of components joined. Effective throat of a weld is the shortest distance from the joint root to its surface.
prognosis: Lead or Lag

I "comangled" my colloquial and formal terms. Partial Pen converts quite nicely to PJP. Full Pen became FJP in my mind, but it is indeed CJP.

You will find that B16.5 flanges often do not make under Apx 2.
