Two fractured 8″ IPS SDR 26 PVC 1120 water pipe specimens were analyzed to determine the causes of failure. The pipes were part of a water distribution system in a condominium apartment complex. The analysis included evaluation of material properties, examination of the fracture surfaces, and fracture stress calculations utilizing linear elastic fracture mechanics. It was concluded from these studies that both pipe specimens failed due to excessive bending of the pipeline sections during the after installation.
