REUSABLE INVERSION SLEEVE ASSEMBLY FOR INVERSION OF CURED INPLACE LINERS

摘要

Installation of a flexible cured in place liner by inverting the liner ut ilizing an inversion sleeve assembly with an installation apparatus having a t least one selectively operable rigid gland. The sleeve assembly includes a sleeve portion of an absorbable material secured in an apparatus with an in version boot fitted at the distal end with an inlet port for inversion and/o r curing fluid. The sleeve assembly and apparatus are particularly well suit ed for inverting with air and curing the liner with steam introduced through a perforated lay flat hose using an apparatus with two glands. The installa tion sleeve is the same dimension as the liner to be installed and is reusab le thereby substantially reducing the set up time to install using the dual gland apparatus. Preferably, the flexible sleeve is a length of dry cured in place liner inverted on to itself to expose two impregnable surfaces. The s leeve may have a built in fluid inlet port for use with a dual gland apparat us.
