Inflatable heating device for in-situ repair of conduit and method for repairing conduit

摘要: The apparatus of the present invention is generally characterized by a heating/inflation module having pressurizable interior and an attached heat curable pre-preg. In particular, elastomeric, seamless composite provided that includes heating element disposed within thermoset resin matrix. adapted to maintain consistent temperature profile internal air pressure. A first end piece has port for communication with compressed source, vacuum supply source at least one electrical cable power source. second composite. further pre-preg removably outer surface structural fiber matrix supporting resin. constructed applying liquid silicone layer braided or wound and/or tape fibers, wherein portion fibers are electrically conductive. introduced into mold, removable, expandable inner bladder then loaded mold. inflated conform An electric current caused flow conductive cure stable, elastomeric state. removed from method repairing damaged section conduit also disclosed.
