TPEP anti-corrosion steel pipe for long-distance water transmission, manufactured by Guanghui Pipe Industry

Description :

　　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, heat, 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 to 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 role in national construction!

　　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 after high-temperature heating and fusion, forming a steel plastic alloy layer, abbreviated as TPEP steel pipe (T, the first letter of three layers in English, 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.

　　Inner oxygen outer polyethylene anti-corrosion steel pipe is a generation of anti-corrosion forms applied to long-distance water transmission pipelines. Compared with traditional transmission 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 the standard construction to ensure the normal use of the pipeline The composite process of TPEP anti-corrosion pipe base pipe and coating mainly involves preheating the base pipe to ensure that the surface temperature meets the temperature range required for plastic powder, and then coating it with plastic powder. Powder coating, also known as dispersion method, can be divided into: spraying: using compressed air to spray plastic powder through a nozzle; Suction coating: Use a vacuum pump to create negative pressure inside the tube and suck in plastic powder; Immersion: Store plastic powder in a container and immerse the preheated base tube in the powder; Rolling molding: Plastic powder is stored on the wall of the base pipe, and the rotating rolling base pipe evenly distributes the powder. Due to the surface of the base pipe reaching a certain temperature, the plastic powder melts and coats the pipe wall, forming a coating and an anti-corrosion layer. Production process: The inner wall of the product adopts thermal spraying epoxy powder anti-corrosion method. The powder is uniformly wrapped and coated on the surface of the pipe body after being heated and melted at medium frequency and high temperature, forming an inner wall anti-corrosion layer that meets the requirements of food grade anti-corrosion.

　　External 3PE internal fusion bonded epoxy composite steel pipe (also known as TPEP anti-corrosion pipeline) is an upgraded product based on external polyethylene internal fusion bonded epoxy composite steel pipe, and is currently an advanced anti-corrosion form for buried long-distance pipelines. The independently developed fourth generation large-diameter pipeline new anti-corrosion production line adopts a three-layer structure of anti-corrosion coating formed by hot melt bonding and winding process on the outer wall, including bottom layer epoxy resin, middle layer adhesive, and outer layer polyethylene. The inner wall adopts thermal spray epoxy powder anti-corrosion method, and the powder is uniformly coated on the surface of the pipe body after high temperature and hot melt bonding. TPEP composite steel pipeline: Its Chinese name is, outer wrapped polyethylene and inner fusion bonded epoxy anti-corrosion steel pipe, which is the fourth generation of long-distance water pipeline anti-corrosion technology, as indicated by its full Chinese name. The outer wall of the pipeline adopts 3-layer PE structure anti-corrosion technology wrapped with polyethylene, and the inner wall adopts hot-melt epoxy anti-corrosion treatment. Use standards to meet food grade standards. It is a truly high-quality anti-corrosion pipeline for transportation.
