This paper outlines a theoretical approach developed to quantify the conditions for a long-running crack in PE gas distribution pipes. Comparisons with a full-scale experiment on a 250 mm diameter SDR 17.6 MDPE pipe are made to demonstrate the validity of the model. The present status of a user-oriented procedure to prevent rapid crack propagation in PE gas pipes is described.
