Abstract:
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.

Claim (Index 1):
A method for applying a barrier coating leak sealant to coat the interior walls in a pipe made of a nonmetal material selected from at least one of plastics, PVC (polyvinyl chloride), composite materials, or polybutylene, with fittings selected from at least one of nonmetal fittings, metal fittings or combinations thereof, comprising the steps of:\n providing a source of compressed air; providing a dry cleaning process; forming a leak coating to fill in a leak; removing moisture from the pipe made of the nonmetal material with the compressed air; cleaning interior wall surfaces of the pipe made of the nonmetal material by the dry cleaning process with the compressed air inside of the pipe made of the nonmetal material; introducing the leak coating into the pipe made of the nonmetal material by a continuous positive pressure from the compressed air in a single sealant stage; and coating the interior walls of the pipe made with the nonmetal material with the leak coating during the single sealant stage.
