Short-Term Hole Spanning Testing and Evaluation for Spray Applied Pipe Lining
Publication: Pipelines 2023
ABSTRACT
Trenchless pipeline technology is an emerging field in both new installation and the rehabilitation process of underground pipeline infrastructure. Polymeric spray applied pipe lining (SAPL) is a rehabilitation technology that is continuously developing to provide solutions for deteriorated pipelines’ design life extension. Polymeric SAPL can be used as a corrosion protection and also as a structural lining inside the host pipe. This research work aimed to develop a methodology and liner design practice for short-term hole-spanning internal hydrostatic pressure testing. The liner material used for this test was a fast-setting pure polyurea. The full-scale hole-spanning laboratory testing evaluated the hole-spanning capacity of pipes lined with polyurea under high-pressure (up to 500 psi) with breach sizes of 0.5, 1, and 2 in. The breaches in the pipe samples simulated the corrosion holes. The liner thickness was designed as class II semi-structural, interactive with the host pipe based on AWWA structural classification. The results of this testing determined the capacity of the liner to renew the high-pressure pipes with corrosion holes. The testing also provided design guidelines to determine the liner thickness when used as a semi-structural application.
