摘要： A coating apparatus is disclosed for applying an activated coating onto an internal surface of a conduit, the coating being activated by mixing at least a first and a second component. The apparatus includes a high-pressure mix gun for mixing the at least first and second components such that the activated coating is generated. A rotary atomizer is operatively connected to and cooperates with the high pressure mix gun for receiving the activated coating from the high pressure mix gun. The rotary atomizer cooperates with the activated coating such that the activated coating is atomized so that application of the atomized activated coating onto the internal surface of the conduit is permitted.

摘要： A material casting assembly for a pipe lining apparatus, the assembly having a housing mounted onto an extension/retraction arm and containing an impingement block controlled by an impingement valve, and a static auger bounded by a rotating cylinder which defines a mixing path to an extrusion chamber. The rotating cylinder has exit ports through which lining material is expelled from the extrusion chamber onto a pipe wall.

摘要： Disclosed herein is a tool for holding a spray painting instrument, such as a painting gun for painting an internal surface of a pipe. In particular, the inventive tool is ideal for painting the interior of curves and angles in a pipe and is capable of moving through and uniformly painting up to 90 degree angles of pipes or hollow tubes. The tool has a hollow central tube for carrying a spray-painting gun and at least two projections extending outwardly from an outer surface of the hollow tube. A retracting arm assembly is provided on each projection. Each retracting arm assembly includes first and second retracting arms and a corresponding force exertion mechanism. In operation, when the tool is inserted inside the pipe, each retracting arm touches the internal surface of the pipe due to an outward force exerted thereon. The tool is movable inside the pipe and adjusts automatically to different pipe diameters. The tool can be used manually or in an automated fashion to push and pull the paint gun and paint the interior of a pipe.

摘要： The present invention provides apparatus, including a pigging tool, that comprises a spraying mechanism configured to move along an inner surface of a pipeline, including a slurry transport pipeline in a minable oilsands facility or plant, and to spray a coating on the inner surface of the pipeline; and a curing source, including an ultraviolet (UV) light source, a microwave source or an RF source, configured to cure the coating sprayed on the inner surface of the pipeline in situ as the spray mechanism moves along the inner surface of the pipeline.

摘要： A 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.

摘要： Methods and systems for cleaning, coating and sealing leaks in existing nonmetal pipes, in a single operation. A nonmetal piping system can be cleaned in one pass by dry particulates forced and pulled by air throughout the piping system by a generator and a vacuum. Nonmetal pipes with nonmetal fittings or nonmetal pipes with metal fittings or nonmetal pipes with a combination of metal and nonmetal fittings can be protected from wear by water erosion and rupturing, extending the life of pipes made of a nonmetal material selected from at least one of plastics, PVC (polyvinyl chloride), composite materials, or polybutylene. Coatings can be applied to nonmetal pipes having diameters up to approximately 6″. Leak sealants of at least approximately 4 mils thick can cover insides of nonmetal pipes, and can include novel mixtures of fillers and epoxy materials, and viscosity levels. A positive pressure can be maintained within the nonmetal pipes during applications. Piping systems can be returned to service within approximately 96 hours.
