its performance is basically determined by the performance of the main plastic. Plastics can be divided into thermoplastics and thermosetting plastics according to their properties after heating. Thermoplastics are generally prepared by taking polymeric resins as basic components, adding a small amount of stabilizers, lubricants or plasticizers (or not). This kind of plastic is characterized by softening after heating, plasticity and repeated molding. Generally, thermoplastics have excellent chemical corrosion resistance, toughness and elongation as analyzed by Wanglei (a pseudonym), a new analyst of GF. The process of plastic coated steel pipe is complex and advanced. The commonly used thermoplastic is polyethylene, which can make the plastic coated steel pipe obtain a smooth plastic film surface. Superior to plastic lined steel pipe. Two layers of plastic lined steel pipe are easy to fall off. Epoxy powder coating is a kind of coating based on powder plastics. The commonly used thermosetting plastics include epoxy resin, phenolic resin, amino resin, etc

the product has good electrical insulation and does not need to worry about electric corrosion. It can be used for a long time in the range of - 40 ° at low temperature and 80 ° at high temperature. The adhesion between the coating and the blank tube is strong, and it will not peel off under external pressure. Polyethylene has good extensibility and can be bent at room temperature. The product has the advantages of good corrosion resistance, high mechanical performance, weather resistance, excellent insulation performance, smooth surface, small friction coefficient and easy construction. At present, the fourth industrial revolution characterized by networking, informatization and intelligence is coming, and the steel industry and steel trade industry are facing a new test and baptism

dfpb heavy protection bimetallic bridge protection pipe wholesale Jixi uses advanced Japanese equipment and hot-dip plastic process to realize the new anti-corrosion pipeline product for internal and external anti-corrosion of steel pipelines. It is an upgrading product of traditional anti-corrosion pipelines, especially suitable for crossing roads with special requirements such as anti-corrosion, compression resistance, exposure, etc. Therefore, compared with the plastic lined steel pipe, the municipal hot-dip plastic cable protection pipe, also known as cable threading pipe, is a new anti-corrosion material. Enter a bear market. Refer to the executive standard: cj/t2008 water supply plastic coated composite steel pipe. In terms of cable protection, in addition to external pressure and environmental corrosion, it is also necessary to consider whether the cable is scratched and insulated by the conduit. Iron ore prices plummeted after peaking in mid February, and the hot-dip plastic cable conduit completely solved the above problems. The anti-corrosion components of epoxy coal tar pitch are epoxy coal tar pitch primer and finish, which are made of epoxy resin and coal tar pitch as the main film-forming materials, adding various anti rust pigments, insulating fillers, toughening agents, leveling agents, diluents, anti sedimentation agents, etc. component B is modified amine curing agent or curing agent as the main material, adding pigments and fillers. Component a of epoxy coal tar pitch anticorrosive steel pipe primer is iron red, and component B is black.

according to the above classification of plastics, plastic powder coatings are also divided into two categories: thermoplastic powder coatings, operator powder coatings and thermosetting powder coatings. However, it should be noted that not all plastics can be used as plastic powder coatings. Therefore, the varieties of plastic powder coatings are less than those of plastics. The electric plastic coated steel pipe can not shrink and deform, and the steel enterprises can also use multi-point hydraulic universal testing machine. The fundamental feature of the machine is that it can complete the large tonnage flowering at low cost. It is the general trend for the steel industry to reduce production capacity. How can we resolve the disadvantages and turn them into great opportunities for transformation and upgrading in the throes of adjustment? Shenwenrong said that the close combination of capacity reduction and cost reduction is a direct means for iron and steel enterprises to improve quality and efficiency. Identify the market layout in advance. There are hundreds of types of steel pipes in the industrial industry. Steel plastic composite pipes are one of them. This kind of composite pipe uses seamless steel pipes and welded pipes as raw materials. A layer is coated inside the pipe to have high adhesion. Some pipes are also coated with epoxy resin. Investment in real estate development generally increased year on year. The advantages of hot-dip plastic cable threading protective sleeve are combined with multiple processes such as pre-treatment, preheating, internal coating, leveling and post-treatment, so as to produce heated and rotated plastic powder that melts according to the capillary principle and penetrates into the pores of the steel pipe

however, plastic coated steel pipes can be divided into internal plastic coated steel pipes, external galvanized internal plastic coated steel pipes and internal and external plastic coated steel pipes according to different plastic coating layers. After more than two years of preparatory work, the internal and external plastic coated steel pipes are also one of the plastic coated steel pipes

after years of continuous research, improvement and application, it has verified that the epoxy powder coating in the pipeline and the single-layer polymer coating on the outer wall are an excellent anti-corrosion scheme for steel pipes. At present, it has become a main product widely used in the market
