Manufacturer direct sales of polyacetic acid coated steel pipe anti-corrosion coated steel pipe

Description :

　　The reason why coated composite steel pipes can replace galvanized steel pipes in a short period of time is that galvanized steel pipes combine the properties of steel pipes and plastic pipes, while also eliminating the disadvantages of steel pipes being prone to corrosion and plastic pipes having poor mechanical properties. Thus, it has been widely applied in various fields of engineering construction in China. Water supply and drainage is an important application field that is closely related to our daily lives. Coated steel pipes can be used in this field. Let our editor analyze the reasons for using coated steel pipes for water supply and drainage. Due to the smooth inner and outer walls, low fluid resistance, no scaling, and good weather resistance of plastic coated steel pipes, they have advantages over other metal pipes and can reduce water loss at the source. At the same time, due to the very small linear expansion coefficient of the coated steel pipe, it is very advantageous as a main water pipeline. Another advantage of coated steel pipe is its water supply advantage, which is that its thermal conductivity is close to that of plastic pipe, and it has excellent thermal insulation performance. Therefore, for the relatively cold northern regions of China, the use of coated steel pipes in winter will not cause water pipe bursts. Therefore, coated steel pipes can be used in various water supply and drainage systems.

　　In conventional production processes, sandblasting generates significant pollution and causes harm to human health, while the heating process consumes a lot of energy, resulting in the inability to produce large-diameter coated steel pipes. To effectively solve the problem of difficult production of large-diameter coated steel pipes, the manufacturing process expert group first started with coating materials, developed and applied elastomeric rust proof coatings, and then introduced protective coatings with good anti-corrosion and hygiene performance. The method of direct spraying at room temperature was adopted to solve the problem of difficult plastic coating production for large-diameter steel pipes. Coated steel pipes have high strength, good rigidity, and high pressure resistance. Due to the plastic coating on the inner wall, the inner surface is smooth, reducing fluid resistance, increasing flow rate, and not scaling, making it difficult for microorganisms to grow. It can fully ensure traffic and usage efficiency, and is energy-saving and environmentally friendly. Steel plastic pipes, with seamless steel pipes and welded steel pipes as the base pipes, are coated with high adhesion, anti-corrosion, food grade hygiene polyethylene powder coating or epoxy resin coating on the inner wall.

　　The product complies with the CJT120-2008 industry standard of the Ministry of Construction. The caliber range is DN15- to DN1200, and it can be coated with flanges and pressure grooves with lengths of 6m, 9m, 12m, and indefinite lengths. The coating wall thickness is between 100 microns and 500 microns, usually 350 microns. Pipeline interface thread connection, flange connection, clamp connection pre-treatment chemical immersion method, physical sandblasting method coating varieties include thermoplastic polyethylene powder (PE), thermosetting epoxy resin powder (EP) and other powder coatings. The water supply galvanized inner coated plastic composite steel pipe made by pre-treatment, preheating, inner coating, leveling, and post-treatment processes is an upgraded product of traditional galvanized pipes. The use of inner and outer coated plastic pipes is already very wide in various fields. For friends who are not very familiar with inner and outer coated plastic pipes, their use is very limited. How to understand the specific application fields of inner and outer coated plastic pipes? Below, we will give you a detailed and step-by-step introduction.

　　In which fields and industries are inner and outer coated plastic pipes applied? After the development of inner and outer coated plastic pipes, our company's pipes have been widely used in many fields. 1. The application of inner and outer coated plastic pipes in long-distance oil and gas transportation, as a major engineering project in China in recent years - the West East Gas Pipeline, has extensively used epoxy powder coated steel pipes for 4000km of transportation pipelines. The external anti-corrosion of the "West East Gas Pipeline" mainly includes epoxy powder coating, double-layer epoxy powder coating, and three-layer PE. Among them, the reinforced epoxy powder coating anti-corrosion is 1560 km, the double-layer epoxy powder coating anti-corrosion is 480 km, and the three-layer PE anti-corrosion is 1960 km. In order to reduce pipeline resistance, the internal anti-corrosion adopts epoxy powder coating. At present, the entire 4000kin main pipeline of the project has been completed. The supporting branch lines and urban pipeline networks have even greater pipe usage. The use of inner and outer coated plastic pipes in long-distance oil and gas transportation pipelines will be a huge application area for inner and outer coated plastic pipes.
