摘要：A method of repairing a pipe ( 11 ) containing a pressurized fluid and having at least one leak, for instance in a flange ( 10 ), including the steps of installing a flexible and sealed casing ( 12 ) engaging the pipe on each side of the leak site to enclose the leak, the casing including a valve arranged at the highest point if the fluid is a gas or at the lowest point if it is a liquid; installing a rigid and sealed casing ( 20 ) engaging the pipe on either side of the flexible casing and enclosing the casing; and injecting a polymerizable liquid material into the rigid casing, so that the flexible casing is enclosed in a sleeve of polymeric resin after polymerization of the polymerizable material.
