Reinforcement Area Overlap, UG-42
Reinforcement Area Overlap, UG-42
(OP)
Hello Everyone
Attach file has case for two nozzle's reinforcement area overlap which is shown by dotted lines.
Can i consider reinforcement limit asymmetric as shown by thick red and blue line ???
ASME SEC VIII Div 1.
Thanks.

The problem with sloppy work is that the supply FAR EXCEEDS the demand

To satisfy this requirement you can choose the limit of reinforcement along vessel wall for each opening to a value lower than the one defined in UG-37 and such that the two limiting circles are tangent; then you check the reinforcement of each opening as if it was isolated.
You can freely choose the two limits in order to favor the opening that needs more (e.g. because it has a thinner nozzle).

Thanks prex, with all respect
But 50% of the summed requirement for reinforcement is for Fig.UG-42.2(b) where three nozzle's reinforcement overlap.
For two nozzle's reinforcement area overlap in UG-42(a) says combined reinforcement that has an area not less than the sum of area required.

Also, is applicable also to a pair of adjacent openings.
So, are you pretending that only a group of two adjacent openings (not a single one, not three or more, not in a flat head) can be designed with asymmetric reinforcements?

My case is of two opening on F&D head.
