Accelerated slow crack growth testing procedures that are coupled with newly developed bi-directional time-temperature shifting functions can provide reliable fracture mechanics based forecasts of long-term service performance of polyethylene gas distribution pipes. This methodology is first reviewed, then used in conjunction with the British Gas notch pipe test. Specific attention has been given to the role of extrusioninduced residual stresses on the service performance of pipe systems. Suggestions are offered for an integrated analysis/testing approach that will enhance the practical usefulness of test data.

It is well known that gas permeation in thermoplastic pipe is proportional to pressure. Accordingly, quantitative consideration must be given to this phenomenon to properly design and operate reinforced thermoplastic composite pipe (RTCP) in high pressure applications. In this paper a permeation predictive model based...

The perceived need to ensure that polyethylene gas distribution pipes are safe from the possibility of long running catastrophic cracks has prompted a significant level of research recently. This paper brings to a completion an ongoing effort by the authors and their colleagues over the last few years. The...

Most current procedures for the design, installation and qualification of electrofused jointsin polyethylene gas piping systems are empirical in nature. To improve this situation, the Gas Research Institute initiated an integrated experimental and analysis research program at the Southwest Research Institute. The...

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...
