What This Spreadsheet Does
Calculates required pipe wall thickness for process piping per ASME B31.3 paragraph 304.1 — the foundational calculation every piping engineer does on every line in every project. Outputs both minimum thickness (t) and nominal thickness (t_nom) including corrosion allowance and mill tolerance.
What’s Inside the Excel File
- Inputs — design pressure, temperature, pipe OD, material allowable stress (S), weld joint quality factor (E), Y coefficient, corrosion allowance, mill tolerance
- Minimum thickness (t) per B31.3 Eq. (3a)
- Pressure design thickness ™ with mechanical allowances
- Required thickness with mill tolerance (T)
- Nominal thickness selection from standard pipe schedules
- Pressure rating at selected schedule
- Equation 3a vs 3b selection for high-temperature service
Who This Is For
- Piping design engineers in process industries
- Mechanical engineers on Oil & Gas, refinery, petrochemical projects
- EPC piping teams
- Stress analysts verifying line schedules

Frequently Asked Questions
B31.3 only or other codes?
This sheet is B31.3 process piping. For UK gas distribution, see our IGEM TD-13 sheet. For pipelines, see our pipe thickness sheets for B31.4/B31.8.
External pressure / vacuum?
This sheet covers internal pressure. External pressure / vacuum collapse requires a different formulation.

What Pipe Thickness ASME B31.3 Calculation — Process Piping Excel calculates
Pipe Thickness ASME B31.3 Calculation — Process Piping Excel is an Excel-native engineering calculation tool built by 3D-LABS for mechanical, design, and equipment engineers working with pressure equipment, rotating machinery, and mechanical systems. It is used for sizing pressure vessels, heat exchangers, flanges, bolts, and other mechanical components. Every input is labelled and every output is traceable — the sheet is designed to be checkable, not a black box.
Codes and standards followed
Pipe Thickness ASME B31.3 Calculation — Process Piping Excel follows ASME B31.3. Each formula in the spreadsheet is cross-referenced to the specific code clause it implements — you can trace any calculation back to the underlying standard, which is essential for design review and regulatory sign-off.
If your project requires a different code base (e.g. converting an IS-code sheet to an ASME basis), we can produce a code-variant edition on request. Contact info@3d-labs.com for a variant quote.
