　　The base materials for anti-corrosion steel pipes include seamless steel pipes, spiral steel pipes, and straight seam steel pipes. Anti corrosion pipelines can be divided into two categories: inner lining anti-corrosion steel pipes and outer wall anti-corrosion steel pipes. The main anti-corrosion methods for lining include cement mortar lining anti-corrosion steel pipes, which are widely used and have lower costs. Cement mortar lining anti-corrosion steel pipes use a cement mortar anti-corrosion layer to prevent corrosion of the pipeline. The commonly used external anti-corrosion pipeline is the 3pe anti-corrosion pipeline. Anti corrosion technology is the process of covering the outer or inner wall of steel pipes with anti-corrosion coatings to protect the pipeline itself. It can process various types of pipes such as straight seam steel pipes and spiral steel pipes. In order to prevent accidents such as personal injury and property loss caused by the transportation of flammable and toxic fluids, the spiral steel pipe factory adopts corresponding process standards, continuously meets important performance operations, and ensures quality and safety in the testing and measurement process for use in the market. How to develop anti-corrosion steel pipes in China in the future? Anti corrosion steel pipes include existing asphalt paint anti-corrosion steel pipes and epoxy paint anti-corrosion steel pipes. In recent years, due to the development needs of the market and the continuous improvement of engineering products, anti-corrosion steel pipe products have also introduced 3PE anti-corrosion steel pipes and cold wrapped anti-corrosion steel pipes. The anti-corrosion system of anti-corrosion steel pipes is basically long-term, and the design life of anti-corrosion steel pipes is generally over 30 years. Whether it's petroleum asphalt anti-corrosion steel pipes, epoxy coal tar anti-corrosion, adhesive cold wrapped tape anti-corrosion, or 3PE anti-corrosion, each type of anti-corrosion has its own advantages. Although petroleum asphalt anti-corrosion and epoxy coal tar anti-corrosion are about to be phased out in engineering use, they cannot be completely eliminated in the short term. In the future, PE anti-corrosion will be the main type of development. Due to the characteristics and features of anti-corrosion steel pipes, they have great advantages in construction and practical needs.

　　The anti-corrosion steel pipe coating, also known as the three-layer polyethylene anti-corrosion coating, is a new type of anti-corrosion steel pipe coating that cleverly combines the 2PE anti-corrosion coating in Europe with the widely used epoxy powder anti-corrosion steel pipe coating (FBE) in North America. It has been recognized and used worldwide for over ten years. 3PE anti-corrosion steel pipe manufacturers have the strength to create high-quality products. The main straight pipe of 3PE anti-corrosion steel pipe is prefabricated with anti-corrosion layer in the factory, reserved with joint filling section, and then welded on site, and then repaired with heat shrink sleeve or heat shrink tape. For the bent pipe part, the current commonly used process is to use heat shrink wrapping tape for the same level of 3PE anti-corrosion. However, the disadvantage of this anti-corrosion process is that it cannot be mechanically assembled on the assembly line, and can only be manually wrapped, which is time-consuming and the material cost is also high. Moreover, the construction quality has a great impact on the quality of anti-corrosion, and quality control is difficult. At present, some design units have developed a new anti-corrosion process using double-layer epoxy and anti-corrosion tape. This process fully utilizes the excellent anti-corrosion performance of high-temperature fusion bonded epoxy powder, and can be sprayed mechanically. The cost of the added anti-corrosion tape is also relatively low. Since its formation, the externally wrapped anti-corrosion tape can serve as the external protective structure of the coating, effectively eliminating the defects of thin thickness, easy detachment and collision of the double-layer epoxy powder coating, and the failure of the anti-corrosion layer. In practical applications, the types of anti-corrosion tape can be selected from polyethylene anti-corrosion tape and polypropylene reinforced fiber anti-corrosion tape. Polyethylene anti-corrosion tape has good ductility and flexibility, while polypropylene anti-corrosion tape has higher wear resistance. Therefore, the current preference is for polypropylene reinforced fiber anti-corrosion tape due to its excellent mechanical strength. Of course, the comprehensive anti-corrosion performance of this process, especially the strength of the anti-corrosion layer, is slightly inferior to that of using hot wrapping tape for anti-corrosion. The pipes are more prone to collision and damage during transportation and construction, and further improvement is needed.
