PSI supports three vessel configurations. The vessel type determines which geometry inputs are shown and how loads are calculated.Horizontal
A cylindrical vessel oriented along a horizontal axis. Requires outer diameter and length. Typically supported on saddles.
Columna Vertical
A vertical cylindrical column. Requires outer diameter and height. Typically supported on a skirt or legs.
Esférico
A spherical vessel. Only requires outer diameter — the length/height field is hidden because the geometry is fully defined by the diameter alone.
Geometry Inputs
The geometry panel collects all dimensional and fluid properties needed to compute vessel weight, projected wind area, and seismic mass.| Field | Description | Unit (SI / US) |
|---|---|---|
| Diámetro exterior | Outer diameter of the vessel shell | mm / in |
| Longitud / Altura | Shell length (horizontal) or height (vertical column) | mm / in |
| Material del recipiente | Vessel shell material — drives density and allowable stress | — |
| Espesor de pared | Nominal shell wall thickness | mm / in |
| Espesor de aislamiento | Insulation layer thickness added to the outer profile | mm / in |
| Nivel líquido (%) | Fill level of the contained fluid, from 0 % (empty) to 100 % (full) | % |
| Gravedad específica del fluido | Specific gravity of the process fluid relative to water | — |
Material Options
The following vessel shell materials are available in the geometry panel:- Carbon steel — general-purpose, highest density, widest temperature range
- Stainless steel 304 — austenitic, good corrosion resistance
- Stainless steel 316 — austenitic with molybdenum, enhanced pitting resistance
- Alloy steel — higher strength grades for elevated temperature or pressure service
How Vessel Data Flows
Vessel parameters are the input foundation for the entire PSI calculation chain. The geometry and weight values feed downstream into each of the pressure element and structural element modules:- Support Design (
/soporte-diseno) — vessel geometry and weight drive the Geometry & Weight card inputs. - Support Analysis (
/soporte-analisis) — operating weight and dimensions inform the analytics metrics and charts. - Weld Design (
/soldadura-diseno) — vessel outer diameter and wall thickness inform attachment weld sizing.
The Vessels page (
/recipientes-analisis) where vessel definitions will be managed is currently under construction. In the interim, vessel geometry is entered directly in the support design input components (GeometryCard).
