Strange Flange Output

I am using the stoomwezen code to calculate some flanges in my system, I am getting a really strange output - see attachment.

My desing temp = -75, not -17.78 as the output suggests. Is it possible that a PEq flange check isn't possible at this temperature or is it something to do with Stoomwezen.

Cheers.

With the Stoomwezen Code, you can only run with one temperature in c2. So regardless of whether you picked T1 to Tmax as the evaluation temperature for the flanges, you should get the same thing.

What was your ambient temperature? Could you have picked Tamb as the flange evaluation temperature?
