    4. Coal tar epoxy
    1).Composition:
    The product is formulated with an epoxy resin, coal tar pitch, anti-rust pigments, additives, modified amine from. Products with rapid drying, good adhesion, flexibility, and easy two-component packaging and construction. With acid, alkali, salt, water, oil etc.;
    2).Characteristics and Uses:
    ①The paint combination of high mechanical strength epoxy resin adhesive force, erosion and chemical resistance characteristics of asphalt water-resistant, anti-microbial, anti-plant roots, is a high performance anti-corrosion insulation coating, the products are Good chemical resistance, water resistance.
    ②suitable for oil, gas and water pipelines, water, gas, pipelines, refineries, chemical plants, sewage treatment plants and pipeline corrosion of equipment, may be used as antiseptic and mining offshore oil rigs and underwater portion of the ship , corrosion downhole equipment.
    3).Coat corrosion:
    High-density polyethylene jacket anticorrosive structure: the outer surface of the pipe wrapped high density polyethylene material with high mechanical strength and excellent corrosion resistance, can protect the pipe to avoid the transportation, installation and use of the process due to external factors damage caused. Manufacturing outer casing should be added antioxidants, UV stabilizers, and carbon black. Polyethylene outer tube easy to aging, such as open storage and other objects appropriate to tarp covered dumps should be kept away from heat and ignition sources, made after anti-corrosion steel, prohibit exposure, quenched, or polyethylene outer tube easy to crack, the impact of product performance and service life;
    4).The process has been the duty epoxy powder coating using electrostatic spraying. Since epoxy powder Jin Su troubled by adhesion, epoxy powder dip has not been able to promote. Current come with three coconut epoxy powder dip developed special phosphate solution, for the first time to overcome the adherence problem epoxy powder dip process, began to dip epoxy powder of this emerging technology;
    5).corrosion standards:
    FBE epoxy powder preservative execution SY/T0315-2005<steel pipeline single FBE topcoat technical specifications>
    2PE / 3PE preservative execution GB/T23257-2009<buried steel pipeline polyethylene outer coating technology standards>
    Anticorrosive surface rust criteria: the outer surface of steel pipe sand-blasting by GB / T8923-2008 requirements of Sa2 1/2 grade steel anchor profile of the surface of 40-100μm;
    6).Applications:
    Anti-corrosion steel base material including spiral, straight seam pipe, seamless pipe, etc., are widely used in our long-distance water, petroleum, chemical, natural gas, heating, sewage treatment, water, bridges, steel, marine water piling pipeline engineering;
    7).Advantages
    ①improve the life of the steel pipe;
    ②combination of mechanical strength and plastic pipe corrosion resistance in one;
    ③outer coating of 2.5mm or more, scratch resistance, bump;
    ④inner wall of the friction coefficient is small, 0.0081-0.091, reduce energy consumption;
    ⑤the inner walls meet the national health standards;
    ⑥smooth wall is not easy scaling, self-cleaning function;
