  • Patent number: 9764354
    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.

    Abstract: An aqueous compressed gas aerosol formulation in combination with a lined steel can, which may also optionally be tin plated, to provide corrosion stability, fragrance stability and color stability. An aerosol formulation of particular advantage for use is an air and/or fabric treatment formulation. The combination provides a compatibility which allows for the ability to use a broader fragrance pallet for the air and/or fabric treatment formulation which is aqueous based in major proportion. The formulation includes, in addition to an aqueous carrier, a fragrance, nonionic surfactant(s) or a blend of nonionic surfactant(s) and cationic surfactant(s), a compressed gas propellant(s), pH adjuster(s), and corrosion inhibitor(s). The formulation has a pH of about 8 to less than 10. The corrosion inhibitor(s) is(are) mild in strength and used in a minor amount.

Furthermore, a chemical including iron (II) ions and formic acid, hydrogen peroxide, and hydrazine are injected into the circulation pipe. Due to the injection of these chemicals, a film formation solution of pH 7.0 including iron (II) ions, chromium ions, formic acid, hydrogen peroxide, and hydrazine is generated in the circulation pipe. This film formation solution includes hydrazine of, for example, 1000 ppm. The film formation solution is supplied to the piping, thus, a Fe3—xCrxO4 film (here, 0<X?0.1) is formed on the inner surface of the piping.

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 from at least approximately 1 to approximately 2 hours.

  • Patent number: 8561569
    Abstract: A combined heating and cooling device for coating the inner walls of pipes may include heating areas and cooling areas. This device can be guided along the pipe to be coated, wherein a fluid containing the coating active agent is supplied to the interior of the pipe. The combined heating and cooling treatment for the pipe supports the process of coating formation. The cooling process is subject to a desired profile by the use of the cooling area and is not determined by chance.

  • Patent number: 8524320
    Abstract: 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 and the pipe coatings. 2-step thermoset resin coating is applied to pipe interiors and inner surfaces of fittings/valves, and exterior ends of the pipes that fit within the fittings/valves “in place” without dismantling the pipes from fittings where the curing agent can be phenol free and plasticizer free adduct. The coating can reduce heavy metals, such as lead, from leaching from installed pipes and fittings 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 from at least approximately 1 to approximately 2 hours.

  • Publication number: 20130202791
    Abstract: A bath containing nickel ions and formic acid is injected into a film-forming aqueous solution flowing in a circulation pipe connected to a feed water pipe made of carbon steel in a BWR plant. This solution is supplied into the pipe through the circulation pipe, and a nickel metal film is formed on an inner surface of the pipe. After the film is formed, a film-forming aqueous solution containing iron (II) ions, formic acid, nickel ions, hydrogen peroxide, and hydrazine is supplied to the pipe. A nickel ferrite film is formed on the surface of the nickel metal film in the pipe. The nickel ferrite film comes into contact with water containing dissolved oxygen at or above 150° C. to transform the nickel metal film into a nickel ferrite film. A thick nickel ferrite film is formed on the inner surface of the feed water pipe.
