Structural Deformation Characteristics of Installed HDPE Circular Pipelines

This study presents a survey of deformation characteristics of the installed high-density polyethylene (HDPE) pipelines. Video and laser inspections are carried out on over 15,000 ft (4,572 m) of buried HDPE pipelines installed across the nation. Different types of deformation failure modes observed in the buried HDPE pipelines are identified in this paper. The results show that the majority of buried HDPE pipelines have deformations in excess of the commonly acceptable limits along multiple locations within each pipeline.
