Six Liu Bao Tel: 18033242424 18823102210 Shantou [preservative] VS Shantou spiral [Spiral manufacture epoxy anticorrosive bituminous coal] spiral pipe wall corrosion is mainly used for buried or submerged steel oil, gas, water, heating pipes corrosion, waterproof and also suitable for various types of steel corrosion leaks, docks, ship, locks, gas tanks, oil refining chemical equipment corrosion and concrete pipes, sewage tank, roof waterproofing, bathroom, basement and other concrete structures medium corrosion spiral steel corrosion media: IPN8710 corrosion spiral steel pipe corrosion more types of media, there is acid, alkali, salt, oxidants and water vapor, coating must be chemically inert, acid salt corrosion, the coating should structure compact, waterproof permeability, adhesion, tenacity fullness. IPN8710 spiral steel corrosion primer: from polyurethane, polyethylene, modified epoxy resin, non-toxic anti-rust pigments, additives and other components, room temperature curing form an interpenetrating network structure is dense coating, acid, alkali, salt, excellent rust resistance, strong adhesion. IPN8710 corrosion spiral steel finish: epoxy, rubber, resin-modified, non-toxic anti-rust pigments, additives and other components. Excellent chemical resistance, non-toxic, anti-microbial erosion. Corrosion spiral steel pipe nominal diameter: diameter spiral pipe corrosion can be divided into outer diameter, inner diameter, nominal diameter. Pipes for pipe corrosion spiral steel pipe outer diameter is represented by the letter D followed by additional outer diameter size and the thickness of, for example, an outer diameter of 108 corrosion spiral steel pipe wall thickness 5MM, with D108 * 5 said plastic tube also with an outer diameter of said that if De63, others such as reinforced concrete pipe, cast iron pipe, galvanized pipe, etc. using DN said that in general use in the design drawings to represent the nominal diameter, nominal diameter in order to facilitate the design and manufacture and maintenance requirements artificially a standard, but also more nominal diameter, is a tube (or pipe) specification name. Nominal diameter of the pipe and its diameter, outside diameter not equal, for example: nominal diameter spiral pipe 100MM Post 102 * 5,108 * 5 and other several, 108 for the pipe diameter, wall thickness of the pipe 5 shows, Therefore, the inner diameter of the pipe is (108 * 5-5) = 98MM, but it is not exactly equal to the pipe diameter minus twice the wall thickness difference, it can be said that the nominal diameter is close to the diameter, but not equal to the inside diameter one kind of pipe diameter specification name, in the design drawings so use nominal diameter, the purpose is to be determined according to the nominal diameter of the pipe, fittings, valves, flanges, gaskets and other structural dimensions and connection size, nominal diameter DN using symbolic representation , if the outer diameter of the design drawings, said it should make the pipe specifications table, show the public some pipeline nominal diameter, wall thickness.
