Abstract

See full text

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