    摘要: A flexible wrapping is adapted to fit around a section of pipe or pipeline requiring repair. The wrapping has inner and outer skins and a plurality of tags for limiting the separation between the skins. The wrapping is sealed in position around the pipe or pipeline by means of straps. A mould forming material is introduced through a filler into the space between the skins and then allowed to solidify. A sealant is then introduced under pressure through an injector into the mound space between the inner skin and the pipe or pipeline. A pressure gauge indicates the pressure in the mould space. Gases may escape from the mould space through a vent. The invention provides a method of and apparatus for repairing a leak in a pipe or pipeline.
