Design pressure & design temperature for a branched line

[Hasab]

Hi everyone,

I want to know if there a case where the design pressure & design temperature of a branched line from an old line can be higher than the ones for that old line? (my opinion no such case exists).

Thanks for the information.

No doubt about it.

Design yes, operating, no.

But it wouldn't male much economic sense.

Some numbers would help.
