20110293827 | METHOD OF REDUCING MAGNETITE FORMATION - A method of reducing magnetite formation in the bore of a pipe including the steps of selecting a pipe with a pre-existing oxide layer on its inner bore surface and coating the pre-existing oxide layer with an oxidation resistant metal to thereby reduce magnetite formation in the bore of the pipe. | 12-01-2011 |
20120015103 | POLYURETHANE FOAM - This disclosure describes a method of making a polyurethane foam and a method of reducing NVH expected to be experienced by a substrate using the foam. When the foam is subjected to 95% relative humidity for a period of 7 days at a temperature of about 50° C., the foam absorbs an amount of water that is less than about 30% of the weight of the foam. | 01-19-2012 |
20120244280 | MULTI-STEP METHOD FOR PRODUCING ALKALI-RESISTANT ANODIZED ALUMINUM SURFACES - The present invention relates to a multi-stage method for producing acid- and alkali-resistant, high-gloss anodized aluminum surfaces. In the method according to the invention, in a first step the anodized surface of aluminum and/or alloys of aluminum is compacted by bringing it into contact with an aqueous composition (A) containing water-soluble alkali silicates having a mol ratio of SiO | 09-27-2012 |
20130202791 | Suppression Method for Corrosion of Carbon Steel Member - 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. | 08-08-2013 |
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 |
20140023782 | COATING FORMULATION FOR THE INTERIOR SURFACES OF CANS - The invention relates to a water-based can inner coating comprising a copolymer or a copolymer mixture of at least one aliphatic and acyclic alkene with at least one α,β-unsaturated carboxylic acid in water-dispersed form, wherein the acid number of the copolymer or of the copolymer mixture is at least 20 mg KOH/g, but not more than 200 mg KOH/g, and at least one water-dispersed or water-soluble curing agent. Inventive can inner coatings are characterized in that due to the good crosslinking of the copolymer or of the copolymer mixture with the curing agent, the cured film on the inner surfaces of metal cans possesses excellent properties in regard to hardness, abrasion resistance and resistance towards hot liquids. | 01-23-2014 |
20140199480 | METHOD OF MANUFACTURING FUEL SYSTEM PART AND FUEL SYSTEM PART - A method manufactures a fuel delivery pipe including a crude metal made of forged iron, a nickel-phosphorus plating layer formed on an inner surface of the crude metal, and a nonmetal paint film formed on an outer surface of the crude metal. The method includes coating the outer surface of the crude metal with paint to form the paint film, machining the crude metal with the paint film formed thereon to form a machined surface inside the crude metal, and electroless plating the machined crude metal in nickel-phosphorus plating solution to form the nickel-phosphorus plating layer on the machined surface. | 07-17-2014 |
20140272133 | CORROSION CONTROL COMPOSITIONS AND METHODS OF MITIGATING CORROSION - Corrosion inhibitor compositions are provided that can include a mixture of one or more transition metals, one or more organic phosphates, one or more inorganic phosphates, optionally a dispersant, and hydroxyphosphono acetic acid and/or salts thereof. Methods of mitigating or inhibiting corrosion of housing or conduits containing aqueous mediums are also disclosed. The methods can include the steps of pretreating the metal conduit with a mixture of one or more transition metals, one or more organic phosphates, one or more inorganic phosphates, and hydroxyphosphono acetic acid, introducing an aqueous medium into the metal conduit, and injecting a mixture of one or more transition metals, one or more organic phosphates, one or more inorganic phosphates, and hydroxyphosphono acetic acid and/or salts thereof into the aqueous medium. | 09-18-2014 |
