Abstract
An automatic leak detection and isolation system for a fluid pipeline (3) comprising a pipeline section (1) through which the fluid flows, the pile line section comprising an inner section (5) through which the fluid flows and a sleeve (9) coaxial with and surrounding the inner section (5) and filled with a hydraulic fluid under pressure. A sensing device (not shown in this figure) is provided for sensing a reduction of the pressure of the hydraulic fluid indicating a leakage from or within the pipeline (3), and closure means (11) are provided, actuable in response to the sensing device sensing a reduction in pressure of the hydraulic fluid to close off one end of the pipeline section (1).
Claims20
An automatic leak detection and isolation system for a fluid pipeline comprising a a plurality of pipeline sections through which the fluid flows, each pipeline section comprising an inner section through which the fluid flows and a sleeve coaxial with and surrounding said inner section, said sleeve shut off at each end of the pipe section and filled with a hydraulic fluid under pressure and which is different from the fluid flowing in the pipeline, a sensing device in said pipeline section for sensing a reduction of the pressure of the hydraulic fluid indicating a leakage from or within said pipeline section, and valve means to one end of each pipeline section actuable in direct response to said sensing device sensing a reduction in pressure of the hydraulic fluid, to close off one end of said pipeline section.
