This Pressure Vessel Design Procedure spreadsheet from 3D-LABS follows ASME standards and gives instant, checkable results for practising engineers — no manual derivation required.
Pressure Vessel Design Procedure covers step-by-step ASME Section VIII Div 1 design procedures for cylindrical shells, heads (hemispherical, ellipsoidal, torispherical, conical), nozzles with reinforcement pad, flanges, and saddle supports — with worked calculations for process plant pressure vessels. Written for mechanical engineers and vessel designers.
What ASME Section VIII Div 1 design procedures are covered?
Shell design UG-27: t = (P x R) / (S x E – 0.6 x P), where P is internal design pressure (MPa), R is inside radius (mm), S is allowable stress from ASME II Part D Table 1A, and E is joint efficiency (1.0 full radiograph, 0.85 spot RT, 0.70 no RT). Ellipsoidal 2:1 head: t = (P x D) / (2 x S x E – 0.2 x P). Torispherical (standard crown/knuckle): t = (0.885 x P x L) / (S x E – 0.1 x P), where L is crown radius (typically equal to OD).
What nozzle reinforcement design is covered?
Area replacement method per UG-37: required area A = d x t x F, where d is finished opening diameter (mm), t is minimum required shell thickness (mm), and F = 1.0 for nozzle perpendicular to shell. Available areas: A1 (excess shell plate) + A2 (excess nozzle wall) + A3 (reinforcing pad) + A41 (shell-to-nozzle weld area). Condition: total available area >= A required. Reinforcing pad outer limit: within sqrt((d_n + 2t_n + t_r) x d_n) from nozzle centerline per UG-36.
What horizontal vessel saddle support design is covered?
Zick analysis for horizontal vessel on two saddles: maximum shell bending moments M1 (at saddle) and M2 (at midspan) from Zick equations. Longitudinal bending stress sigma-L = M / (pi x R^2 x t). Combined stress check: sigma-L + (P x R)/(2 x t) <= S allowable. Recommended saddle angle: 120 degrees. Stiffener ring required when R/t ratio exceeds 10 for thin-shell stability.
