Title: THE LINING OF PIPELINES OR PASSAGEWAYS
Abstract:
The invention provides that a tubular lining (12), suitable comprising an inner felt layer soaked in curable synthetic resin, and an outer impermeable layer, so everted into a pipeline or passageway by means of a gaseous fluid medium which holds the lining against the passageway surface, a pull tape or cord (24) which is inside the lining and emerges from the everting face so that tension can be applied thereto, and a lubricating medium (26) inside the everted portion to enable the inwardly travelling uneverted portion to slide over the previously everted portion.
