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. |
