摘要：A method for inverting a tubular liner in a hollow conduit involves: forming acuff from the tubular liner, the cuff having an opening through which the liner is fed; andwhile feeding the liner through the cuff opening, feeding a gas under pressure through a

gas inlet port formed in the liner to a space between the cuff and the remainder of theliner, thereby causing inversion and inflation of the liner into and through the conduit.After a portion of the liner has been inverted in the conduit, a region of the cuff and linerupstream of the gas inlet port is sealed off, thereby causing inversion of the remainder ofthe liner in the conduit. Optionally, before a trailing end of the liner is fed through theopening of the cuff, the trailing end is sealed to prevent flow of gas therefrom. When theliner is intended to line the conduit, the liner resin-impregnated either outside or in theconduit and, after complete inversion of the liner in the conduit, the resin is cured and theends of the liner are sealed to the inside surfaces of the conduit. An apparatus andsystem for conducting the method are also provided.
