Patent abstract
A lining apparatus and method is provided that obviates the need for a bladder to press the liner against the host pipe. The lining apparatus may include an extension tube sealed to the liner at one of its ends with an inversion mechanism attached to the other end of the liner for inverting the liner to its desired position within the pipe to be repaired. The lining apparatus can also avoid the use of an extension tube by temporarily closing the liner during the inversion process so that the liner can be inflated when pressurized by a fluid and then sealing an open end of the liner after it has been inverted into the pipe.
