Abstract

Pre-stressed concrete water pipelines are commonly helically wrapped with highly stressed wire. Although passivated by use of high pH concrete coating, these wires can corrode and break, ultimately resulting in catastrophic failure of the pipe. The failure of these wires releases stored acoustic energy into the walls of the pipes, and into their contents. Continuous acoustic monitoring of the water column in the pipe using various methods can reveal the condition and rate of deterioration of the pipe. This paper discuses the evidence that the method is workable, and suggests a three-stage approach to efficiently examine long pipelines with no interruption in service.
