RESIN IMPREGNATION TOWER FOR CURED IN PLACE LINER

摘要

A non-pressurized resin impregnation tower (54) for continuously impregnating the resin impregnable layer of a tubular cured in place liner (55) is provided. The tower (54) is at a height to provide sufficient resin pressure head to impregnate the resin impregnable layer fully. The resin impregnated tube (55) is fed into the top of the tower (54), drawn down about a roller at the bottom, removed from the top of the tower (54) and then wrapped with an outer impermeable coating. The impregnated liner (55) is suitable for pull-in-and-inflate method of installation or may be everted. For liners formed with an inner impermeable layer, the Linner is suitable for curing with steam.
