Collective Effects of Leakage, Temperature Changes, and Entrapped Air during Hydrostatic Testing

ABSTRACT: During hydrostatic testing of pipelines, leaks in the test section will result in a loss of test pressure, and a reduction in water temperature during the test hold time will also typically result in a pressure decrease. This paper reports an analysis of the comparative...

ILI and NDE Characterization of Pipeline Manufacturing Flaws and Confirmation through Full-Scale Testing

ABSTRACT: Pipeline-manufacturing flaws, such as slivers, can be difficult to accurately characterize and size during in-line inspection. After discovery of longitudinal flaws of varying depth and length, full-scale burst tests and metallography were conducted to confirm the size...
