Abstract:

Pipeline infrastructure and its safety is critical for the recovering of U.S. economy and our standard of living. Statistics from U.S. Department of Transportation (DOT) and Gas Technology Institute (GTI) show the decline in use of steel and cast iron piping materials is significant in recent years and the increase in pipeline system size is largely due to plastic pipe installations. However, failure inevitably occurs in plastic piping materials and impingement failure is caused by high localized stress concentration combined with defects and inclusions. The object of this project is to fundamentally understand and characterize the failure modes and associated material behaviors for modern plastic piping materials. The proposed optimized diagnosis and prognosis approach is thoroughly investigated. The dominating polyethylene (PE) materials (which make up nearly 97% of current plastic pipes) and the emerging thermoplastic (PA) pipes that can operate at much higher pressures and be installed using existing PE tools and techniques are compared.
