We have noticed that the software systematically considers all jackets as type 2 in the jacket closure calculation following PD 5500. We need you to integrate the concept of type 1 jackets in the next version to facilitate support for this type of jackets.
We also noted that for the calculation of jacket closures according to ASME A-9 the software systematically considers the formula used for the jacket closer figure 9-5 sketch (f-1) (f-2) (f-3).
Please correct the software to allow the calculation of the thickness of the jacket closer with the correct formula following appendix 9 of ASME VIII Div 1
