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...

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 This must be notified though, that this standard is out of use, and has been superseded by EN 1993-1-6 for a while.Kindly please add this to...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 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 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...

API650 tanks can only be calculated with ASCE, sometimes it is required EN norms for wind and seismic design

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.

Greece is a country with high seismic behaviour. Many industrial projects are on going in Greece, it would be beneficial to add Greek seismic code.

A summary table will be presented in the main user interface which will list the components (like shell, head, nozzle, cone body flange etc.) along with the corresponding calculated stresses, allowable stresses, calculated minimum required thickne...

Nozzles design: Please provide an opction that considers the alternative calculation method when there is an insert forged pad
