ABSTRACT:
A system for detecting leaks in a pipeline includes an outer containment pipe or jacket surrounding a pipe and defining an interstitial space therewith. A plurality of zone fittings are disposed within the containment pipe or jacket to divide the interstitial space into a plurality of zones. Individual external sensors are attached to the containment jacket at each of the zones for detecting the presence of fluid leakage into the interstitial space. The sensors generate an output signal which is operatively connected to visual and/or audible alarms.
