摘要： 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 μg/L (10 ppb). When cured, specific leachates, Bisphenol A and Epichlorohydrin from the coatings will be (less than)

摘要： 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.

摘要翻译： 在单一操作中清洁，涂覆和密封现有管道中的泄漏的方法和系统。 管道系统可以通过发电机和真空通过管道系统中被空气强制和拉动的干燥颗粒一次清洗。 管道可以防止水腐蚀，侵蚀和电解，延长铜，钢，铅，黄铜，铸铁管和复合材料等管道的使用寿命。 涂层可以应用于直径大约6“的管道。 至少约4密耳厚的泄漏密封剂可以覆盖管道的内部，并且可以包括填充剂和环氧材料的新型混合物和粘度水平。 在施工过程中，管内可保持正压。 管道系统可在大约96小时内恢复使用。

摘要： 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).

摘要： 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 ⅜″ 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.

摘要： Methods, processes and systems for cleaning, coating and sealing leaks in existing pipes, in a single operation. A process can include isolating, draining, drying, cleaning and sealing a piping system. Air can be forced and pulled 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.
