Before the anticorrosion treatment of the 3PE anticorrosive steel pipe base material of electric power, communication, expressway and other cable protection sleeves, the steel pipe entering the pipeline platform needs to be inspected and recorded, the outer surface of the steel pipe is shot blasted and derusted, and then the outer surface of the steel pipe Check the cleanliness and anchor depth to see if it meets the requirements. If it does n’t meet the requirements, use a hand wheel to grind and repair it. Wrap the tape at the end of the pipe, dust treatment, intermediate frequency heating to the required temperature, epoxy powder spray, adhesive extruder side winding , PE extruder side entanglement, water cooling of the anticorrosion tube, spray marking of qualified products, down tube platform, stacking to be shipped. In order to prevent the explosion caused by the transportation of flammable and toxic fluids, it is a personal injury or loss of property In case of accidents, the spiral steel pipe factory adopts the corresponding process standards to continuously meet important performance operations, and guarantees quality and safety in the market during inspection and measurement. The anti-corrosion lining mainly includes cement mortar lining anti-corrosion steel pipe, which has more applications and lower cost. The cement mortar lining anti-corrosion steel pipe uses the anti-corrosion layer of the cement mortar to play the anti-corrosion effect on the pipeline. The three materials are integrated into one, and firmly combined with the steel pipe to form excellent anti-corrosion Floor.
At present, the application effect of anticorrosion coatings at home and abroad is well evaluated. Defects generated during use are rarely reported. The experimental environment includes soil, water, and the test mainly checks stress corrosion cracking. The experimental anticorrosion is to treat defective polyethylene anticorrosion coatings. The steel pipe is placed under corrosive conditions and stress conditions. The corrosion environment is a sandy environment containing NaHCO3, the temperature is 70 ℃, the pipe ground potential is -430 ~ -460mV, the surface of the steel pipe is pre-treated in different ways, and all steel pipes are under pressure. The anti-corrosion needs to be based on the specific requirements of the customer. If it is an ordinary anti-corrosion outside the casing, the ordinary level is more than enough. If it is used to directly take the fluid, such as acid, alkali, natural gas, etc., use the enhanced level. 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, coating leak detection, storage of anti-corrosion pipes. The anti-corrosion insulation pipe technology is usually to add anti-corrosion coating on the outer wall of the spiral pipe to reduce corrosion, so as to prolong the life of sewage treatment discharge pipes, sewage pipes and biological pool anti-corrosion projects.
