Stress Analysis - Buried Line Pipe (Demo)

This tool is developed to perform stress analysis on buried steel line pipe to ensure code compliance under maximum operational conditions. Please refer to applicable design codes and standards for allowable limits. For pipelines at road/railway/water crossings, or any other locations with external loads other than soil, please refer to other tools available in our website.

Calculation of Stresses

Notes :

  1. Pipe ovality calculated as per ALA Guidelines using Iowa Deflection formula.
  2. Since no live load on the pipe, a deflecion lag factor of 1.0 is used.
  3. Allowable limits are per ASME B31.4. Users shall confirm allowable limits based upon service type, pipe location, welding, and temperature in accordance with applicable codes and standards.
