Design Procedure and Test Method to Prevent Rapid Crack Propagation in Polyethylene Gas Pipe

摘要

Rapid crack propagation (RCP) is a phenomenon involving a running axial crack that may travel long distances at high speeds in a pressurized pipeline. It has been observed in large-diameter steel gas-transmission pipelines. The report describes the results of extensive full-scale field tests and modified Robertson tests that were run on 11 lots of PE2306 and PE3408 pipes to study RCP in polyethylene pipes.
