Estimating the term…
A method for repairing a tubular conduit by lining the inner wall of the tubular conduit with a tubular liner bag impregnated with thermosetting liquid resin, having the steps of: (a) everting the tubular liner bag in the tubular conduit; (b) closing the open end of the tubular liner bag with a stationary lid thereby forming a closed space inside the tubular liner bag and the lid; (c) inserting a heat-resistive hose into the closed space through the lid; (d) inflating the tubular liner bag by charging a pressurized fluid into the closed space; and (e) supplying hot water via the heat-resistive hose to thereby heat and harden the liner bag; wherein the heat-resistive hose is slidably inserted through the lid, and is connected to the lid via a flexible inflatable sealing device such that when the pressurized fluid is charged into the closed space the sealing device is pressed to inflate externally from the lid thereby forcing the heat-resistive hose to slide externally.
A method for repairing a tubular conduit by lining the inner wall of the tubular conduit with a tubular liner bag impregnated with thermosetting liquid resin, comprising the steps of:
A method for repairing a tubular conduit by lining the inner wall of said tubular conduit with a tubular liner bag impregnated with thermosetting liquid resin, comprising the steps of:
A flexible inflatable sealing device for repairing a tubular conduit by lining the inner wall of the tubular conduit with a tubular liner bag impregnated with thermosetting liquid resin, comprising a sealing tube for sealing a heat-resistive hose and a lid means, wherein said heat-resistive hose is inserted through and slidably attached to said lid means via said sealing tube in a manner wherein a lower end of said sealing tube is attached to an outer surface of said heat-resistive hose and an upper end of said sealing tube is fastened to said lid means and evertable upward relative to said lid means, and said heat-resistive hose is slidable upward and externally relative to said lid means upon inflation of said sealing device.
