Abstract:
A method for lining a pipe conduit with a coated textile tubing that adheres to the inner walls of the pipe conduit by means of an adhesive. The coated textile tubing can be filled with a long pot life adhesive and the textile tubing turned inside out (inverted) while being introduced into the pipe conduit. A fast curing adhesive is substantially simultaneously applied to the inner wall of the pipe conduit in as short a distance as possible to the moving tubing inversion point. The introduced tubing is then subjected to an inner pressure to force the tubing into contact with the pipe inner wall until the fast curing adhesive has cured. Alternatively, an impregnated textile tubing can be substituted for the tubing filled with the long pot life adhesive. As a further alternative, conditions are controlled to cause curing of the adhesive only in the inverted portion of the tubing.
