Abstract

An external pipe leak repair technique is provided for arresting a leak occurring on an operating pipe in conjunction with an external pipe reinforcing sleeve arrangement. An installation apparatus is first placed over the leak to remove and divert the flow of errant fluids from the leak to create a safe working environment. Then a lea k- arresting plug is placed over the leak and an elastomeric portion of the plug is press ed into the leak. After cleaning in the vicinity of the leak, the leak-arresting plug is affixed to the pipe using a binding agent. Then the outer surface of the pipe and the inner surface of the pipe reinforcing sleeve are cleaned, and an epoxy filler material is applied to the pipe over the area to be covered by the external pipe reinforcing sleeve and over the leak- arresting plug. A depression is ground into a part of the sleeve to accommodate the protruding leak-arresting plug and binding agent above the pipe's outer surface. The sleeve is then installed around the pipe to mechanically support the leak- arresting plug. The leak-arresting plug, binding agent, and epoxy act both as a filler agent and sealant, arresting the leak and filling all voids between the pipe and the sleeve. Th e leak-arresting plug prevents the pipe from leaking, the sleeve prevents the anomaly fromrup turing, and the binding agent I epoxy acts as a secondary mechanism to prevent product leakage. The pipe sleeve therefore act as one unit, expanding and contracting with fluctuations in the pipe's pressure and temperature.
