ABSTRACT:
A contained pipeline and leak detection system having a plurality of pipeline sections adjoined to one or more fluid reservoirs, and a method of detecting leakage in the system are provided. Each pipeline section includes a primary pipeline section and a secondary pipeline section disposed around the primary pipeline section, defining an interstitial space therebetween. The pipeline sections are adjoined by a fitting that maintains fluid communication between the primary and secondary pipeline sections, and the interstitial spaces. Fluid is disposed within the interstitial spaces and the fitting such that fluid entering or exiting the interstitial spaces or the fitting, changes the volume of fluid in the fluid reservoir. An alarm system is connected to the fluid reservoir having a sensor that detects changes in the volume of fluid in the fluid reservoir.
