Hi JohnBreen,
sorry about being off topic. I didn't really start a new thread because my question raised from your previous answer of 14Dec06, where you stated:
If you are convinced that you want to do calculations to show that using the fitting provides the area replacement required by B31.8 Appendix F, simply slice a weld-o-let in half longitudinally and sketch the zone of reinforcement (as defined in Appendix F) on the sectioned fitting with a "Sharpie" and measure the dimensions of the reinforcement provided in the reinforcement zone by BF. Then use the rules of Appendix F. Alternately, call Bonny Forge and ask them to email you a certification that in fact the fitting provides the necessary reinforcement
I proceeded as you suggested, measuring a 'slice' of a BonneyForge weldoled, and I verified that it complies with the requirements of Asme B31.8, but not with those of a ASME Div VII.
We are talking about a Pipeline Temporary Test Head, that has to be itself pre-tested prior being connected to the pipeline. So it can be regarded as a pressure vessel, and this is were our client requirement comes from.
So I found it strange that I couldn't find a weldolet that comply with ASME Div VIII.
Actually, I also contacted BonneyForge for clarification, and they answered me that their weldolet do comply with ASME DivVIII, and that calcultations can be provided when ordering the item.
But honestly, basing on the weldolet dimentions derived from Bonney Forge and WFI catalog, I couldn't verify the requirements of ASME Div VIII, so I'm still wondering what I'm doing wrong
I hope I've been clear enough, because my english is quite poor, and thanks a lot for you answers always very interesting
