ABSTRACT:
A pipeline system with a localized environment for preventing, detecting, and containing leakage from a subterranean pipeline transporting hydrocarbon liquids and gases is disclosed. A steel pipe is enclosed in a sleeve of high density polyethylene and overlaid with a layer of geotextile material. Positioned in the interstitial space between the pipe and sleeve is a layer of geotextile material impregnated with hydrated lime which dissolves in the presence of water to create a highly alkaline solution to protect the pipe. Also positioned adjacent the inner layer are leak sensors/monitors for detection of leaks of hydrocarbon fluids and aqueous solutions.
