How to Use This Calculator
  1. Enter Design pressure (barg), Design temperature (°C), and Inner diameter (mm).
  2. Set Tan-to-tan length (mm), Allowable stress S (MPa), and Joint efficiency E.
  3. Adjust Corrosion allowance (mm), Head type (0=hemi, 1=ellip, 2=tori) as needed.
  4. Review Required shell thickness (mm) and Required head thickness (mm).
  5. Use Total volume (m³) and Total volume (liters) to inform your decision.
