ABSTRACT:
The present invention relates to apparatus for applying heat to a portion of a pipeline, particularly a pipeline carrying natural gas, for the purpose of curing a heat shrinkable plastic sleeve used to repair leaks in the pipeline wall. The apparatus comprises an elongate manifold 1 for mounting on the pipeline and having an inlet 5 to receive hot gas from a forced draught gas burner 6 and an outlet 8 to discharge the hot gas along the portion of the pipeline. The apparatus also comprises a flexible blanket 2 of a heat insulated material such as illuminated glass wool and having one edge 71 for securing to the manifold 1 so that the blanket 2 can be wrapped around the portion of the pipeline to form therearound a heat shroud having openings 75 and 76 respectively to receive hot gas from the manifold outlet 8 and to discharge the gas after circulation around the wall of the pipeline 26.
