Resumen:

Several gravity fed water supply pipelines in Mexico, and worldwide, have suffered bursts under relatively low operating water pressures, compared to their rated pressure. This paper analyses the possible causes, with emphasis on those of them that are known in material science but normally not considered in pipeline design, and even in the corresponding norms and standards. Among these are: hydraulic transients, presence of air pockets, material fatigue due to demand variation or hydraulic transients, and rapid crack propagation. Information about an ongoing study on causes of multiple bursts in an operating polyvinyl chloride (PVC) pipeline is also presented. © 2013 Taylor & Francis Group, London.
