PE Pipe HDD Stress Analysis (HDPE)
Polyethylene pipe behaves very differently from steel during an HDD pull: it is viscoelastic, so its safe pull strength depends on load duration and temperature, and thin-wall PE can collapse under external borehole pressure. This calculator checks the three limits that govern a PE installation — tensile pull-back load, bending strain, and external-pressure (buckling) collapse.
It follows ASTM F1962 and PPI TR-46, the standard references for placing PE pipe by HDD.

- Time- and temperature-adjusted safe pull strength (tensile)
- Bending strain through the minimum bore radius
- External-pressure collapse (unconstrained buckling)
- Combined tensile + bending demand vs. allowable
