If the opening diameter is equal to vessel diameter, which ASME rules are to be used ? Is PV elite capable for this ? If we are using standard tee, can we use fabricated tee also ? Please reply this query with reference to UG-36, Appendix-1-7 & Appendix-1-10.Is WRC 107/WRC 297 applicable for such opening ?

Seamless "Tee" is the best option for that situation. I dont think so the geometry will be within limitations of WRCB-107 or 297 standard.

you could probably use the pipe-pad module in CodeCalc that can model size-on-size connections. That is based on the piping code ASME B31.3.

ASME pressure vessel code Sec. VIII Div-1 (1-7) has limitation that nozzle can be at most 70% of shell diameter. In a quick look, I could find the paragraph for 1-10, but read the cautionary note at the end of 1-10.

WRC 107/297 has even smaller limitations.

I think your best bet is the piping code and the pipe-pad module in CodeCalc.

Dear Experts,

Sorry to drag the old conversation.

1. While I am using the pipe-pad module in codecalc for area reinforcement of run - branch connection (Insert Nozzle with reinforcement) as per B31.3, I can't able to get the report correctly which means the report is generated for Abutting nozzle with reinforcement.

And also, I cant able to find any option for mentioning the type of nozzle attachment in codecalc like pvelite. Automatically it takes the nozzle arrangement as Abutting nozzle.
Kindly Clarify.

2. And also, I didn't find any limitation of branch size on run pipe as per B31.1. But as per B31.3, there are limitations in 304.3.1 section.

But my component should be designed as per B31.1. So, Can I use B31.3 rules to B31.1. Is it acceptable???
