Description
ASME B31.4: Liquid Pipeline Wall Thickness & Hoop Stress β method, governing standards and output schedule
The ASME B31.4: Liquid Pipeline Wall Thickness & Hoop Stress calculation establishes the minimum pressure-design wall thickness for a pipe run and confirms that the selected schedule, after deduction of corrosion and mechanical allowances and mill undertolerance, still satisfies the code requirement. It is applied during detailed design, during design verification by a second engineer, and again during in-service assessment when the operating basis changes. Because every intermediate quantity is reported rather than only the final answer, the calculation can be checked line by line against the governing standard without re-deriving it.
This 3D-LABS workbook is built to ASME B31.4. You supply 11 inputs and the sheet reports 6 results, with every formula left visible so each figure can be traced to the clause it comes from.
Method of calculation
Pressure design thickness is computed as t = PΒ·D / (2Β·(SΒ·EΒ·W + PΒ·Y)) for straight pipe, with the Y coefficient taken from the code table as a function of material and temperature. Thickness for bends, branch connections and miscellaneous loadings is then added, followed by corrosion and erosion allowance and threading or grooving depth, and the total is compared with the nominal wall less mill undertolerance.
Governing standards and references
- ASME B31.4 β ASME B31.4 Pipeline Transportation Systems for Liquids and Slurries
- ASME B31.3 β ASME B31.3 Process Piping, para. 304.1.2
Each formula cites the clause it comes from on the same row as the result it produces, so a reviewer can check the sheet line by line against the standard.
Acceptance criteria
For the calculation to be reported as acceptable, the nominal wall thickness less mill undertolerance and all allowances must equal or exceed the pressure design thickness, and the MAWP at the selected schedule must cover the design pressure.
Who uses this calculation
This calculation is used by piping and pipeline engineers preparing line class documents, and integrity engineers assessing remaining thickness against code minimum.
