Is there a connection like UW-13 for direct connection of Body flange to spherical heads?

[goutam_freelance]

Please see VIII-1 MA1 Fig 1.6 for permissible types of bolted dished cover joints.

Please ignore Mandatory Appendix 2(Flanges), Fig 2-4 shown above as it is for bolted piping joints (apologies).

Once more you are wrong

IT SEEMS IMPOSSIBLE for you to understand what the OP says in his NOV 2 sketch: the body flange is a WELDING NECK, it is full penetration butt weld !

Referring to Fig MA1 Fig1.6, the weld type indicated by OP may not be covered by code.

Also, Type C( bolted dished end ) connection needs to meet additional requirements of weld due to bolt forces and moments, refer MA1, Cl. 1.6.

@ goutam
You are very confused.
I'm sorry to tell you, but I suggest you take some pressure vessel training.

I do not agree. However you can disagree as you have the right to do so even though there may be some impediment here.

I stop this here as nothing will come out of this from me more than what has already been said. Anyone can leave it or take it.

Again, you are not helping the OP.
Do you have any experience with the OP issue?
