Pressure Vessel Calculator
Calculate pressure vessel parameters including wall thickness, stress levels, volume, and weight based on material properties, pressure, and dimensions.
Step 1: Vessel Dimensions
Pressure Vessel Design Basics
Wall thickness calculations are critical for pressure vessel safety. Thicker walls handle higher pressures but increase weight and cost. Always follow ASME or other applicable codes for pressure vessel design.
Step 2: Material & Pressure
Safety Factors in Design
Safety factors account for material imperfections, manufacturing defects, and unexpected operating conditions. Higher safety factors (3.5-4) are used for hazardous contents or uncertain conditions, while lower factors (1.5-2) may be acceptable for well-understood applications.

Pressure Vessel Design Formula
Minimum Thickness = (P × R) / (S × E – 0.6 × P) + C
Where: P = Design Pressure, R = Inner Radius, S = Allowable Stress, E = Joint Efficiency, C = Corrosion Allowance. This formula is based on ASME Boiler and Pressure Vessel Code Section VIII Division 1.
