Abstract: Under current practice, the pressure rating capabilities of a polyethylene gas piping system is determined on the basis of a well established method that was originally developed for forecasting long term performance of PE pipe. The performance capability of heat fusion PE fittings is essentially inferred through tests that compare fitting to pipe performance under certain prescribed conditions. A new theoretical proposal for more precisely forecasting system performance for ambient and higher temperatures is reviewed and the significance of the predicted values upon current fitting pressure rating design practice is discussed. Although it is unheard that a field failure has been discovered that can be attributed to fitting failure due to internal pressure, recommendations are made based on the additional insight suggested by this newly proposed theoretical approach. The essential recommendation is that for service conditions above 60 psi and 73 F consideration should be given to assuring that each PE gas piping component can provide the anticipated service life.
