20140182622 | Methods and Systems for Abrasive Cleaning and Barrier Coating/Sealing of Pipes - Methods for abrasive cleaning, deburring pipes, providing barrier coatings and sealing leaks in existing pipes, in a single operation. Pipes can be cleaned in one pass set up by intermittent bursts of dry particulates that are forced and pulled by air throughout the piping system by a generator and a vacuum. Pipes can be protected from the effects of water corrosion, erosion corrosion and electrolysis, extending the life of piping systems such as copper, steel, lead, brass, cast iron piping and composite materials. Cleaning includes, intermittently injecting bursts of abrasive particles into pressurized gas into the pipes to clean pipe interior walls, reduce burrs and interior lips in pipe interior walls, while generating a vacuum suction in the pipes to remove abrasive particles and debris. | 07-03-2014 |
20130344241 | Coatings, Materials and Processes for Lead and Copper Water Service Lines - Methods, processes, compositions and systems for preventing leaching effects from drinking water service 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 μg/L (10 ppb). When cured, specific leachates, Bisphenol A and Epichlorohydrin from the coatings will be (less than) <1 μg/L (1 ppb) with overall TOC levels measured at (less than) <2.5 mg/L (2.5 ppm). Pipes can be returned to service from at least approximately 1 to approximately 2 hours. | 12-26-2013 |
20130157209 | Portable Heating Apparatus for Heating Interior Piping Systems - Devices, apparatus, systems and methods of using a portable heater that does not use a separate compressor or blower or vacuum. The heater can be attached to a piping system to dry interior walls and/or heat coatings in the piping system. The heater can be attached to a manifold having alternative inlet end and two outlet ends. The manifold ends can have quick connect fittings with similar fittings to be easily mateably attached by rotating fittings with one another. A quick connect/disconnect air pressure regulator with quick connect fitting can be attached to the manifold ends. A quick connect/disconnect plug with similar quick connect fitting can close the manifold ends. | 06-20-2013 |
20130074970 | Methods and Systems for Coating and Sealing Inside of Piping Systems - Methods and systems for cleaning, coating and sealing leaks in existing pipes, in a single operation. A 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. Pipes can be protected from water corrosion, erosion and electrolysis, extending the life of pipes such as copper, steel, lead, brass, cast iron piping and composite materials. Coatings can be applied to pipes having diameters up to approximately 6″. Leak sealants of at least approximately 4 mils thick can cover insides of pipes, and can include novel mixtures of fillers and epoxy materials, and viscosity levels. A positive pressure can be maintained within the pipes during applications. Piping systems can be returned to service within approximately 96 hours. | 03-28-2013 |

20100096384 | Portable Heating Apparatus for Heating Interior Piping Systems - Devices, apparatus, systems and methods of using a portable heating unit that does not use a separate compressor or blower or vacuum. The unit can be attached to an inlet of a piping system or section and be used to dry the interior walls of the piping system or section, and/or heat coatings passing through the piping system or section, etc. The portable heating unit includes a heater attached to an inlet end of a manifold, where the manifold can include alternative inlet end and two outlet ends. The inlet and outlet ends of the manifold can have quick connect fittings that allow similar fittings to be easily mateably attached thereto by rotating the fittings with one another. A quick connect/disconnect air pressure regulator with similar quick connect fitting can be attached to anyone of the inlet and outlet ends of the manifold. A quick connect/disconnect plug or plugs with similar quick connect fitting can close off any of the inlet and outlet ends of the manifold. The portable heating unit can be used with both a separate compressor and blower/filter having vacuum generator. The portable heating unit can also be used with only a compressor. The portable heating unit can also be used with only a vacuum generator. | 04-22-2010 |
