Quick answer
Piping Thickness Calculation covers calculating wall thickness and pressure design per ASME B31 for every line class. Done properly, it follows ASME B31.1, ASME B31.3, ASME B31.8 and produces 3d piping model that a fabricator or reviewer can use without rework. Structural Engineering Services delivers piping thickness calculation to clients in 40+ countries with a senior-engineer review on every package.
The standards that govern piping thickness calculation
Piping Thickness Calculation is governed by ASME B31.1, ASME B31.3, ASME B31.8. Which one leads depends on the project location and the owner's specification — a US refinery package and a European commercial building may need the same discipline executed to entirely different rules.
Beyond the headline code, most projects layer client specifications on top: operator standards (Shell DEPs, Saudi Aramco SAES, ADNOC), fabricator preferences and local authority requirements. A good piping thickness calculation partner maps all of them into a compliance matrix at kick-off.
How code compliance is demonstrated
Compliance is shown through documentation, not assertion. Your package should include:
- Design basis / basis-of-design note referencing the governing code and edition.
- Calculation reports with load combinations and acceptance criteria.
- Drawings flagged with the applicable code and material grades.
- A documented checker's review with sign-off.
- Revision-controlled transmittals so the latest code-compliant issue is unambiguous.
Common compliance mistakes
The most frequent compliance failures we see in piping thickness calculation are edition drift (working to a superseded code edition), mixing code systems mid-package, and missing project-specific overlays. Each is avoidable with a kick-off compliance matrix and a senior review gate.
Working across multiple jurisdictions
Global projects often need one package that satisfies several jurisdictions. We deliver piping thickness calculation to ASME B31.1 and ASME B31.3 routinely and maintain checklists for each, so multi-code packages are reviewed against every governing standard, not just the primary one.
