Description :

　　TPEP anti-corrosion steel pipe, also known as outer 3PE and inner fusion bonded epoxy anti-corrosion steel pipe, is an upgraded product on the basis of outer single-layer polyethylene and inner epoxy composite steel pipe. It is a steel pipe anti-corrosion situation that is now being introduced for buried long-distance pipelines. TPEP is an anti-corrosion structure and a generation of anti-corrosion forms applied to long-distance water pipelines. Compared with traditional pipelines, it has many advantages and features. The external anti-corrosion of the pipeline is 3PE, and the internal anti-corrosion of the pipeline is fused epoxy powder. The anti-corrosion standard of the inner wall of the pipeline has reached food grade The TPEP anti-corrosion steel pipe project can be buried and used for 50 years according to national standards to ensure the normal use of the pipeline.

　　The tpep anti-corrosion process (inner EP and outer 3PE) combines thermosetting epoxy resin powder coating with the characteristics of polyethylene and processing technology, and cleverly combines the three-layer structure polyethylene coating with fusion bonded epoxy powder coating technology, providing a good solution for the corrosion protection of buried steel pipes. The inner wall fusion bonded epoxy resin powder (FBE) anti-corrosion solves the problem of internal anti-corrosion of pipelines, with low roughness, smooth inner walls, and good hydraulic performance. Through the analysis of design examples, it is concluded that compared with pipes of the same diameter, the use of inner wall fusion bonded epoxy coating can reduce pipeline losses by more than 30%; Under the same flow rate, the pipe diameter can be reduced by one level, thereby reducing costs and energy consumption. It has become a widely used main product in the market for large-diameter water transmission pipelines.

　　TPEP anti-corrosion steel pipe refers to a steel pipeline that has undergone anti-corrosion processing and can effectively prevent or slow down the occurrence of chemical or electrochemical reactions that cause corrosion during transportation and use. Anti corrosion steel pipe base materials include spiral pipes, straight seam pipes, seamless pipes, etc., which are widely used in pipeline engineering fields such as long-distance water transportation, petroleum, chemical, natural gas, thermal, sewage treatment, water sources, bridges, steel structures, and marine water transportation pile driving in China. TPEP anti-corrosion steel pipes have a diameter range of Φ 60~Φ 1420 and a wall thickness range of 2.5-18mm. This is a relatively good anti-corrosion method, which can generally achieve a service life of 50 years. It not only extends the replacement cycle of underground pipeline equipment, but also greatly saves costs, providing a strong and effective role for the construction of domestic facilities!

　　TPEP anti-corrosion steel pipe - external 3pe anti-corrosion and internal fusion bonded epoxy anti-corrosion is an upgraded product based on the external single-layer polyethylene and internal epoxy composite steel pipe. It is currently the anti-corrosion form of steel pipes for buried long-distance pipelines. It is a fourth generation large-diameter pipeline new anti-corrosion production line independently developed for anti-corrosion steel pipes. The outer wall adopts a three-layer layout of hot-melt bonding and winding process, with the bottom layer of epoxy resin, the center layer of adhesive, and the outer layer of polyethylene forming the anti-corrosion layer. The inner wall adopts a thermal spray epoxy powder anti-corrosion method, where the powder is uniformly coated on the surface of the pipe body after high-temperature heating and fusion, forming a steel plastic alloy layer, abbreviated as TPEP steel pipe (T, three layers of English Three letters, PE refers to polyethylene, EP refers to epoxy resin). Ji has significantly improved the adhesion and thickness of coatings, enhancing their resistance to bumps and corrosion. This product obtained a national utility model patent in 2009. Received the National Torch Project in 2010. TPEP steel pipes fill the gap in anti-corrosion of domestic steel pipes, and the cost is almost the same as that of single-layer polyethylene fusion bonded epoxy composite steel pipes. The corrosion resistance has improved by 3-5 times.
