Abstract: A distribution system for delivering preheated epoxy material for spray application includes a bundle of lines that terminate on their far end in a manifold. The distribution system is uniquely constructed in a manner such that it delivers the correct materials individually to the manifold while maintaining separate flows of the materials. This separation of the materials until ready for spraying prevents mixing of the two-part epoxy which at the elevated delivery temperatures would result in early curing of the epoxy within the delivery system itself. The bundle of lines contains at least one and preferably two base epoxy delivery lines, at least one catalyst delivery line and at least one heating circuit. The manifold terminates in a static mixer that in turn delivers the mixed epoxy to a spray head for spray application to the substrate.

Abstract: A method and system for the spray application of epoxy materials is provided. The system includes a dual walled tank structure as a reservoir for containing and preheating the epoxy materials in preparation for mixing and spray application. Each component of the epoxy material is preheated before the components are mixed. After preheating, the components are then mixed together and spray applied. The method and system of the present invention provides a high quality spray applied epoxy coating while reducing equipment down time and cleaning.

Abstract: A method and system for evaluating the interior surface and exterior wall conditions of a pipeline while also dynamically installing a repair coating in a pipeline, such as an underground water pipeline. The system is towed into the pipeline and drawn back therethrough. As the system is drawn back, one module in the system evaluates the surface condition of the interior of the pipe and another module evaluates the structural condition of the wall of the pipe. Based on the evaluation data obtained from the two modules an epoxy material is applied to the interior surface of the pipe using a spin cast machine that is drawn behind the two modules. Preferably, a layer of epoxy is applied to the interior surface of the host pipe to the appropriate thickness based on the pipe condition as determined by the two modules.

Abstract: A pipe lining composition and a method for installing the pipe lining composition into a pipeline requiring repair is provided. The lining composition is a layered lining composite formed of alternating plies of felt and carbon fiber strand reinforcing such that layers of carbon fiber reinforcing strands are trapped between layers of felt. Once the composite is laid up the composite is preferably stitched to provide stability and to maintain the layers relative to one another and then formed into a tube. In accordance with the method, the lining tube is then sequentially filled resins of increasing viscosity as it is drawn through rollers in a manner that fully wets out the carbon fiber before it is placed into the pipe to be lined.

Abstract: The present invention is an improved method for installing a liner to repair a pipeline. The method involves placing a flexible lining hose that is coated with a thermosetting resin into the pipeline. A quick setting resin is also applied to the interior walls of the pipeline wherein the resin has a high contrast pigment agent therein in order to facilitate identification of and reopening of the various service laterals. A calibration hose is introduced into the lining hose and pressurized fluid is injected therein. The fluid presses the lining hose against the interior surface of the pipeline and cures the first and second thermosetting resins. The curing of the resins bonds the lining hose to the pipeline to form a rigid monolithic composite structure having high mechanical strength.
