  • Patent number: 10449569
    Abstract: Methods, processes, compositions and systems for preventing leaching effects from water pipes (such as lead, steel and copper) having an inner diameter of at least approximately 12 mm. 2-part thermoset resin coating is applied to the inner surfaces of the pipes where the curing agent can be a phenol free and plasticizer free adduct type. The coating can reduce heavy metals, such as lead, from leaching from installed pipes to less than approximately 10 ?g/L (10 ppb). When cured, specific leachates, Bisphenol A and Epichlorohydrin from the coatings will be (less than) <1 ?g/L (1 ppb) with overall TOC levels measured at (less than) <2.5 mg/L (2.5 ppm). Pipes can be returned to service within approximately 24 hours, and preferably within approximately 4 hours. The methods, processes, compositions and systems can work with non-metallic pipes having metal valves and/or metal fittings.

  • Patent number: 10076769
    Abstract: Methods and systems for providing cleaning and providing barrier coatings to interior wall surfaces of small diameter nonmetal and composite piping systems in buildings, swimming pools, underground pipes, in-slab piping systems, piping under driveways and various liquid transmission lines. An entire piping system can be cleaned in one single pass by dry particulates forced by air throughout the building piping system by an external generator, and the entire piping system can be coated in one single pass by a machine connected exterior to the piping system. Small pipes can be protected by the effects of water corrosion, erosion and electrolysis, extending the life of piping systems such as plastics, PVC (polyvinyl chloride), composite materials, polybutylene.

  • Patent number: 10076770
    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.

  • Patent number: 9555453
    Abstract: Methods for abrasive cleaning, existing pipes before coating interior surfaces which extends the life of piping systems such as copper, steel, lead, brass, cast iron piping and composite materials. The method can include the steps of generating pressurized gas into pipes to generate a moving air stream, intermittently injecting separate spaced apart bursts of abrasive particles into the moving air stream with different cumulative amounts of the intermittent bursts of the abrasive particles that vary based on different piping diameters, cleaning interior wall surfaces of the pipes with the intermittent bursts of the particles, reducing at least one of burrs or interior lips in the interior wall surfaces of the pipes, with the intermittent bursts of the particles and removing abrasive particles and debris caused by each one of the separate burst shots of the abrasive particles.

  • Patent number: 8887660
    Abstract: Methods and process steps for mapping, cleaning and providing barrier coatings to interior walls of piping systems. An entire piping system can be cleaned in one single pass by dry particulates forced by air and the piping system coated in one single pass. Pipes can be protected from water corrosion, erosion and electrolysis. Pipes having diameters of approximately ?? up to approximately 6? are treatable. Piping systems such as potable water lines, natural gas lines, HVAC, drains, and fire sprinkler systems in homes, apartments, high-rise hotel/resorts, office towers, high-rise apartment and condominiums and schools, can be treated. The coating forms an approximately 4 mils or greater covering inside the pipes. Buildings can return to service within approximately 24 to approximately 96 hours.
