The present invention relates to a method and system for applying a resin impregnated seal onto a junction between a branch pipe and a main pipe. The seal comprises a tubular part defining a first opening and a second opening opposite the first opening, and a brim portion attached to the tubular part at the first opening and extending radially outwardly from the tubular part. The method and system comprises providing a sealing apparatus including an elongated housing, an inflatable ring structure having an integral radiant energy source, a flexible guiding tube and a mobile radiant energy source, positioning the flexible guiding tube such that the closed end is located outside the housing, positioning the brim portion of the seal juxtaposed the inflatable ring structure, positioning the housing inside the main pipe, fixating the brim portion to the main pipe, inverting the seal, positioning the mobile radiant energy source inside the tubular part, irradiating radiant energy from the integral radiant energy source for curing the brim portion and irradiating radiant energy from the mobile radiant energy source for curing the tubular part. |
