Please add the possibility to perform a fatigue analysis directly in ASME VII Div.1 without choosing Div.2. When I choose Div.2, all the calculations and the allowable stresses are of course different.

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 ...

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...

The allowable pressure of flanges as per EN1092-1 can be defined by formulas or by table. In the past AutoPipeVessel was giving the table allowable pressure. In the new version, it's the calculation with the allowable stress of the material. It wo...

In the case of sketch f) of table 4, the factor C can rise to 0.45 if s > 3 s1. Nowadays, there is no way to get C = 0.45 with the models of flat heads offered by Autopipe Vessel.

Add an option to override the selected bolt area. This can be helpful when non standard neck-down bolt is used.

Add compressive stress calculation according to EN13445 16.14.8 instead of PD5500 when the calculation code is EN. Allow calculation to be selected manually. Also provide control on factors relevant to calculation such as Cx, Cbx, Q, Tolerance cla...

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

This option is only available when floating head heat exchanger is calculated, for normal vessels it is not possible to use a crown (hemispherical) head welded direct into a flange without knuckle or straight flange.

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).
