Abstract

See full text

A pipe-liner system for use when lining a pipe interior features a pipe having a pipe opening end and a pipe interior wall. The system features a flexible, substantially-impermeable, elongate extender-tube and an evertable, flexible, elongate, tubular pipe-liner. The system features a substantially leak-proof pressure retaining closure-sleeve located on a pipe-liner second end. An extender-tube second end is attached to a pipe-liner first end via a substantially leak-proof connection there between. The combined extender-tube and the pipe-liner form a single continuous evertable tube, hereinafter referred to as an extended liner having the pressure retaining closure-sleeve enclosing an extended liner distal end. A length of the extender-tube and a length of the pipe-liner are each chosen so that the liner is caused to be accurately positioned within the pipe upon eversion.
