Condition Investigations of HDPE Pipe In-Service in the United States
This study consisted of inspecting 39 High Density Polyethylene (HDPE) Pipes located in 6 different states. The diameters of the pipes ranged from 28 to 60-in. The inspections consisted of diameter measurements, distress documentation, alignment measurements, and still and video photography. The tables below present a list of the pipes inspected by state. The state names have been omitted in this report at the request of the American Concrete Pipe Association (ACPA) in respect for the states that assisted in identifying the HDPE pipe locations. Pipe deflection, distress, and misalignment problems are listed.
