With the objective of defining parameters that can be used to assess the condition of PVC joints in the field, more than two-hundred destructive tests were done in the laboratory. Two diameters (110 mm and 315 mm) of new PVC double-sockets were tested. The occurrence of leakage during water pressure tests, intrusion during vacuum tests and characterization of joint stiffness during rotation were monitored. The results clearly demonstrate that leakage and intrusion do not occur for typical operational situations (angles below 10 degrees) if the rubber ring is in perfect condition. The joint's stiffness increases with the increase of inner-pipe pressure, diameter and with the level of insertion. Insertion plays the most relevant role. The results also show that the condition of a joint cannot only be defined by its angle, but that an extra parameter is necessary: the level of insertion.read more

Long-Term Performance Prediction for PVC Pipes
TL;DR: In this paper, the Awwa Research Foundation and CSIRO funded a study in order to outline an approach to estimate in-service lifetimes for (unplasticised) PVC-U (commonly called PVC), (modified) PVC-M and (oriented) O pipes, as well as the influence of manufacturing and installation practices on these lifetimes.

Full-Scale Experimental Determination of Concrete Pipe Joint Behavior and Its Modeling
TL;DR: In this paper, a simple rheological bilinear model of the joint is elaborated from compression and shear tests and then validated on the experimental bending results, and a good agreement is found between model and experimental output.

Study on failure rate analysis for water distribution pipelines
TL;DR: In this article, the authors apply reliability engineering in the waterworks field as one possible approach and to show its viability; it will also obtain vital messages revealed within pipeline incident data, such as cumulative failure distribution (unreliability) by pipeline material, the failure probability density and failure rate, among others.

TL;DR: In this article, the authors investigate the behavior of lead-caulked cast-iron pipe joints and estimate the degree of settlement that two or more contiguous segments of a pipe can tolerate before failure.
