Pipestra Stress (beta)
Linear static pipe stress analysis in your browser. Model the line in a table, add supports and load cases, and check it to ASME B31.3 or EN 13480-3. You get a 3D utilisation plot and a PDF report. Nothing to install, and your model stays on your computer.
Beta: allowables are sample values, results must be verified by a qualified engineer, no liability.
