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.
What piping thickness calculation actually includes
Piping Thickness Calculation is the discipline of calculating wall thickness and pressure design per ASME B31 for every line class. In practice a complete scope covers the full chain from design inputs to construction-ready output, not just a single drawing or calculation.
A typical piping thickness calculation package from our team includes: 3d piping model, piping ga & isometric drawings, stress analysis report, pipe support drawings. Each deliverable is produced on licensed CADWorx, CAESAR II, AutoCAD Plant 3D, Smart P&ID and passes an internal checker review before it reaches you.
How the work is delivered, step by step
Most engagements follow the same five-stage flow, whether the package is a single drawing or a multi-month frame agreement.
- Share inputs — design drawings, specifications and the project schedule.
- Free quote in 24 hours — fixed lump-sum, per-tonne, per-drawing or hourly.
- Model & engineer — built on CADWorx to ASME B31.1.
- Review & approve — internal check, then your comments closed fast.
- Issue for construction — 3d piping model and piping ga & isometric drawings issued with revision control.
Which codes and standards govern piping thickness calculation
The governing standard depends on where your project is built. Our teams work daily to ASME B31.1, ASME B31.3, ASME B31.8 and to client specifications such as Shell DEPs and major operator standards.
Getting the code basis agreed at kick-off is the single most effective way to avoid late-stage rework — it fixes load combinations, material grades, tolerances and documentation format before modeling starts.
When you need it — and when you don't
You need professional piping thickness calculation whenever the output feeds fabrication, regulatory review or a design-responsibility handover. Early concept sketches and feasibility studies can be lighter, but anything issued for construction should carry a checked, code-referenced package.
If you are unsure which level of detail your project needs, send us your inputs — a senior engineer will scope it honestly, even if that means telling you a smaller package will do.
