Body Flange MAP limited by bolting

[jsyoon]

Hello.

I am desige some heat exchanger using COMPRESS.

In some S&T heat exchanger, MAP is lower than MAWP. but I can not understand this case. this MAP is governed by channel flange. and In the calculation report, it is specified "Bolting limits" next to the this MAP. I guess that certain moment between bolting on body flange and gasket is limiting this MAP.

Is there anyone to solve this?

Thanks.
