Data Source and Methodology
All calculations are based on the ASME Boiler and Pressure Vessel Code, Section VIII Division 1. More information here.
The Formula Explained
\( t = \frac{P \times D}{2 \times S \times E - 1.2 \times P} \)
Glossary of Variables
- P: Internal Pressure (psi)
- D: Inner Diameter (inches)
- S: Allowable Stress (psi)
- E: Joint Efficiency (assumed as 1 for seamless)
- t: Required Thickness (inches)
Example Calculation
Let's consider a vessel with an internal pressure of 150 psi, a diameter of 30 inches, and an allowable stress of 15,000 psi. The required thickness is calculated using the formula above.
Frequently Asked Questions (FAQ)
What is the ASME Code?
The ASME Code provides rules for the design, fabrication, and inspection of boilers and pressure vessels.
When should I use this calculator?
This tool is intended for use during the preliminary design phase when quick estimates are required.
Can I use this for all materials?
The calculator assumes the material properties meet ASME specifications. Always verify with detailed material analysis.
Why is joint efficiency assumed as 1?
This assumption is valid for seamless vessels. Adjustments may be necessary for welded joints.
What if my vessel has different conditions?
Consult the full ASME code for complex or non-standard conditions.
