The use of 3PE polyethylene anticorrosive insulation pipe

    At present, pipeline anti-corrosion technology has been widely praised in the actual application in the market. Pipeline anti-corrosion technology has been used in industrial equipment such as construction, petroleum, power, metallurgy, national defense, transportation storage, boilers, heat exchangers, fans, vehicles and ships. Among them, the anti-corrosion insulation pipe technology is usually to add anti-corrosion coating on the outer wall of the spiral pipe to reduce corrosion and achieve extended life. At present, the main external anti-corrosion coatings for spiral pipeline anti-corrosion are three-layer PE polyethylene, epoxy resin powder, epoxy coal pitch and so on. It can produce epoxy powder anticorrosive insulation pipe, epoxy coal asphalt anticorrosion steel pipe, etc.

    The use of three-layer PE polyethylene and epoxy resin powder anti-corrosion coatings has the following advantages: high-efficiency waterproof and anti-corrosion, insulation and low temperature resistance. The main buried pipelines in foreign countries in Europe and America should also be these anti-corrosion coatings. At present, China ’s comprehensive durability and maintenance For cost considerations, the first choice is a three-layer PE polyethylene composite structure anti-corrosion coating. The specific process of the three-layer PE polyethylene in the spiral anticorrosive insulation tube is as follows: spiral tube intermediate frequency heating, shot blasting rust removal treatment, rust removal quality inspection, intermediate frequency heating, epoxy powder coating, adhesive application, polyethylene application, water cooling Treatment, leak detection of coating, storage of anti-corrosion tubes.
