    摘要： A method of lining an interior wall of a pipe is provided. Casting equipment such as a spin caster is used to centrifugally cast material onto the interior wall while the pipe is partially filled with liquid so as to form a coating on the wall above the liquid. In some embodiments the method further comprises diverting liquid from the pipe after the casting step, and then lining the wall of the pipe below the coating with material to form a continuous lining on the wall.

    摘要： 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. Coatings can be applied to pipes having diameters of approximately ⅜″ up to approximately 6″ so that entire piping systems such as potable water lines, natural gas lines, HVAC piping systems, drain lines, and fire sprinkler systems in single-family homes to apartments to high-rise hotel/resort facilities and office towers, apartment and condominium buildings and schools, can be cleaned and coated to pipes within existing walls. The coating forms at least a 4 mils or greater covering inside of pipes. Buildings can return to service within approximately 24 to approximately 96 hours.
