Leakage Performance of Joints in Gravity Flow Pipes Subjected to Shear Force, Angular Misalignment, and Diameter Deformation



Current standards for quality control testing of joints in gravity flow pipelines specify tests that do not evaluate conditions that have been registered in full-scale laboratory tests and are estimated using simplified design equations, particularly the shear forces transferred across the joint. In this research study, the leakage performance of joints in reinforced concrete, corrugated high-density polyethylene, and corrugated steel pipelines is evaluated when joints are subjected to expected service conditions. To do this, a testing apparatus that is capable of applying expected demands in a controlled fashion while the pipeline is subjected to internal or external fluid pressures was developed. It was observed that shear force and diameter changes controlled the leakage resistance of those joints, and that some were more susceptible to leakage when subjected to internal pressure compared to external pressure. The results are used to establish recommendations regarding test procedures of joints for culverts and other gravity flow applications.
