When manufacturing vessels according to AD 2000 or ASME, experience can be obtained for nozzles located within a distance less than 2,5√(ea*r) from tangent line knuckle/cylindrical part. We would therefore like the possibility to chose this option...

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...

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...

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 ...

In the designing of tall structures, especially tall process columns, the use of DIN 18800 proved helpful. This must be notified though, that this standard is out of use, and has been superseded by EN 1993-1-6 for a while.Kindly please add this to...

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...

Allow the user to inser the combinaton fator for internal pressure (Fp) and the combination factor for external pressure (Fpe) as refered in API 650 paragraph 5.2.2.

We have a pressure vessel that must be designed in accordance with ASME Section VIII, Division 1. However, for full face gasket flanges, the software by default performs the calculations according to PD 5500 (Slip-on loose flange – BS/PD 5500 §3.8...

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.
