Sometimes is needed to increase locally the thickness of the vessel wall to reinforce the nozzles (under pressure load or external loads), instead of increasing the whole course or head thickness (for economic reasons). Simulating this local thick...

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...

AutoPIPE's Node Annotations (Insert > Node Annotations) are not able to be printed on a Stress Isometric. Using the "save isometric drawning" prompt, we have the option to isert annotations (but it's not a good way to do it), and it's not relat...

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 ...

As per the note in read on the top of this page, please bring back the user accreditation program

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.

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.

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

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...
