Hottest plastic impregnated steel cable protective

Hot dip plastic steel cable protective tube

hot dip plastic steel cable protective tube is a new type of anti-corrosion steel produced by fluidized bed impregnation process and new film-forming process. Polymer materials with different formulations are uniformly coated on the metal surface through special equipment. After plasticization and curing, a uniform, dense and smooth plastic coating is formed on the metal surface, which becomes a new type of steel plastic composite pipe. It combines the superior mechanical properties of steel with the chemical corrosion resistance of polymer materials. This process ensures that the adhesion between the coating and the pipe reaches * and the adhesion per square centimeter reaches 50~70 kg, and the adhesion will not decay in long-term use. The coating thickness is about 300 microns, which cannot be achieved by the spraying process. According to the medium and working conditions, the hot-dip plastic steel pipe is based on the surface treatment of ordinary steel pipe, so the anti-corrosion performance is far better than that of PVC materials of similar domestic products at present. The hot-dip plastic steel cable protection pipeline product adopts high-quality steel, which is an upgraded alternative product of the plastic steel pipe or electrostatic nozzle with the operating advantages of the original coating tensile machine (this kind of product adopts the physical advanced treatment process). Coating application epoxy resin accounts for a large proportion of the application in coatings. It can be made into varieties with different characteristics and uses

the hot-dip plastic steel cable protective tube mainly has the maintenance effect on the wires, so the leakage of electricity is impossible. So far, plastic coated steel pipe manufacturers are changing these advantages. They have a relatively smooth pipe wall without any burrs. During construction, large-diameter plastic coated steel pipes inside and outside are suitable for crossing cables, perhaps wires. The skill of plastic coated steel pipe has been very experienced in foreign industrialized countries. Plastic coated steel pipe has been widely used in many fields, such as petroleum, chemical industry, construction, shipbuilding, communication, electric power, underground gas transmission pipeline, etc. 80% to 90% of the pipes of large-diameter internal and external plastic coated steel pipes, such as the United States, Japan and other countries, choose plastic coated steel pipe. Epoxy resin powder steel plastic composite pipe. It has strong chemical stability and corrosion resistance, good mechanical properties and high compressive strength, and can play a very good protective role for cables. Different plastic coatings can meet the requirements of external temperature of -40 ℃ -90 ℃, and are suitable for high and low voltage cable threading

the hot-dip plastic steel cable protection pipe is based on the surface treatment of ordinary steel pipes, and adopts polymer materials with different formulas according to the use medium and working conditions. At this time, it needs to remove the cleaned special equipment and apply it evenly to the metal surface. After plasticization and curing, a uniform, dense and smooth plastic coating is formed on the metal surface, which becomes a new type of steel plastic composite pipe. It combines the superior mechanical properties of steel with the chemical corrosion resistance of polymer materials. These Formosa Plastics are unable to achieve. For iron and steel projects under construction and urban steel plant relocation projects, the construction feasibility should be reassessed on the basis of reduced development in combination with the current situation, so as to prevent the emergence of new insolvent enterprises; For insolvent and defaulting enterprises, Bai Rui mentioned how to reduce logistics costs through intensive transactions, but with the saturation of houses and roads, how to turn the current point into a grid in the future. Moreover, these enterprises are not within the scope of the statistics of the iron and Steel Industry Association and the all China Metallurgical chamber of Commerce. They belong to local areas, and the vast majority of them are backward production capacity divorced from the task of capacity removal

hot dip plastic steel cable protection tube is mainly suitable for telecommunication cable threading protection, power engineering cable threading protection, transportation and communication cable threading protection, petroleum, chemical industry, urban construction and other fields. Internal and external plastic coated steel pipe is a kind of steel pipe produced by both internal and external plastic coating technology. Both internal and external plastic coating makes the corrosion resistance of steel pipe better and its service life longer. The common pipes in the early market mainly include steel pipes and plastic pipes. Although ordinary steel pipes have high strength, they are easy to rust, and are easy to be polluted, so their service life will be relatively short; Although plastic pipes have good corrosion resistance and strong finish, they are prone to deformation due to the influence of temperature, and are relatively fragile and easy to crack. The emergence of plastic coated steel pipes can well integrate the advantages of the two, and can solve the use defects of the two

the plastic coated steel pipe for cable threading has good adhesion with the steel pipe. Although (c) the plastic coated steel pipe for cable threading has thermal expansion and cold contraction when the water temperature changes, it will never appear delamination. The coating at the interface has very strict technical requirements. Under the pressure of 1.0MPa, there will be no leakage, and the anti-corrosion performance is reliably guaranteed. The plastic coated steel pipe is used for cable threading, and the plastic lined steel pipe is originally composed of two layers. Even if the bonding force of the polyethylene lining pipe is far less than that of the plastic coated steel pipe, the plastic coated steel pipe for cable threading is easy to produce delamination under the condition of thermal expansion and cold contraction. Moreover, both the screw thread and flange connection at the interface are weak links. The steel pipe will be rusted between the plastic pipe and the steel pipe, causing the corrosion prevention failure of the overall pipeline and greatly reducing the service life. Because plastic coated steel pipe and plastic lined steel pipe have the characteristics of high corrosion resistance and light weight, the processing methods and materials are different, resulting in the difference in service life and price. The performance index of plastic coated steel pipe is far better than that of plastic lined steel pipe. The market price of plastic coated steel pipe is slightly higher than that of plastic lined steel pipe due to the high price of coating, complex processing methods and high cost. Plastic coated steel pipes have better quality, low failure rate and longer service life than plastic lined steel pipes
