I've created the flange check files for Case 2901. If anyone interested, it will be necessary to delete .txt in the back of their name. After that it should be placed in ProgramData Caesar System folder.
Since the coefficient FM is different pending on the pipe size I had to split in to. One is for pipes up to 12" the other 12" up to 24".
These are simple text files based on the ASME-2009.flg & ASME-2009.G
where the values were multiplied by (1+FM) as per Case 2901.
Maybe someone will find useful. Of course you need to check first
as you are the only responsible.
