MANDATORY APPENDIX 13 VESSELS OF NONCIRCULAR CROSS SECTION Rectangular cross section vessels.

For vertical vessels I suggest to add a field to add a material for lugs on top o f the vessel and also another field to selected the material for lugs on bottom skirt (tailing lug). It is very common to have columns in for exempla stainless steel...

Please can we update the API 650 calculations as well as the user interface. Africa is booming in storage of petroleum. This means we need API 650 more and more here. AutoPIPE can have the edge here compared to other softwares. We can use it as a ...

When API650 is not suitable for a vertical tank, calculation should be done with API620

API 620 design for storage tanks

Floating roof modeling and design for storage tanks

In the case of horizontal vessels, it must be possible to lock both sadles in order to carry out a correct calculation under transport conditions (taking into account longitudinal acceleration on both sadles).

It should be possible to impose a weld bead dimension in the "brackets and lifting accessories" masks. This value is set at 0.7 x the minimum thickness of the shell or wear plate. In the case of large thicknesses, this results in an unfeasible wel...

It would be useful to add the verification of the stresses during lifting when the equipment is inerted with nitrogen at 0.5 barg (or with another gas at another pressure). The temperature could be also selected (room or higher temperature). The e...

Please add the possibility to design the attached nozzle. I regularly have this kind of model and the fatigue analysis is not possible in APV.
