APPARATUS, METHODS, AND LINERS FOR REPAIRING CONDUITS

摘要

An apparatus and method for repairing the juncture or intersection of a first conduit (15) and a second conduit (8) is disclosed. The apparatus includes a main body (1) for transporting and positioning a repair material impregnated with a heat curable resin system or matrix. An inflation device and caul plates carried by the main body position and compress the repair material against the intersection. This includes a portion of the interior of the second conduit and flange portion in the first conduit. The inflation device and caul plates include conductive fibers that are electrically resistively heated to effect curing of the resin in the repair material. Additionally, a method and liner apparatus for the in-situ repair of conduits having large diameters is disclosed. The liner comprising a plurality of discrete heating zones, where each zone impregnated with a curable resin.
