Manufacturer produces and processes TPEP anti-corrosion steel pipes with epoxy powder inside and 3PE anti-corrosion steel pipes outside Guanghui Pipe Industry

Description :

　　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 to provide a solution for the corrosion protection of buried steel pipes. The inner wall fusion bonded epoxy resin powder (FBE) anti-corrosion solves the internal anti-corrosion problem of pipelines, with low roughness, smooth interior, 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 mainstream product widely used in the market for large-diameter pipelines.

　　TPEP anti-corrosion spiral steel pipe for water transmission - external 3PE internal fusion bonded epoxy anti-corrosion steel pipe is an upgraded product based on the external single-layer polyethylene internal epoxy composite steel pipe, and is currently the anti-corrosion form of steel pipes for buried long-distance pipelines. It is the fourth generation new anti-corrosion production line for large-diameter pipelines independently developed by Cangzhou Guanghui Pipe Industry Co., Ltd. The outer wall adopts a three-layer structure of anti-corrosion coating formed by hot melt bonding and winding technology, with the bottom layer of epoxy resin, the middle layer of adhesive, and the outer layer of polyethylene. The inner wall adopts a thermal spray epoxy powder anti-corrosion method, and 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, the initial letter of three layers in English, PE refers to polyethylene, EP refers to epoxy resin).

　　The service life is over 50 years. The TPEP anti-corrosion pipeline used in domestic water and electricity engineering projects is developed and produced by Zhongwo Pipeline. The application of external 3PE and internal fusion bonded epoxy composite steel pipes solves the problem of internal and external anti-corrosion of pipelines. The pipeline has 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 pipeline loss of steel plastic composite pipes can be reduced by more than 30%; In the case of conveying the same flow rate, the pipe diameter can be reduced by one level, thereby reducing costs and energy consumption. In long-distance water and gas transportation processes, it is recommended to prioritize the use of external 3PE and internal fusion bonded epoxy composite steel pipes. TPEP anti-corrosion steel pipes have a diameter range of Φ 60~Φ 1420. PEP is an anti-corrosion structure used for 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 fusion bonded 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. TPEP anti-corrosion steel pipe - external 3PE internal fusion bonded epoxy anti-corrosion steel pipe is an upgraded product based on the external single-layer polyethylene internal epoxy composite steel pipe, and is currently an advanced form of steel pipe anti-corrosion for buried long-distance pipelines.

　　Comparison between inner oxygen outer single-layer PE and inner oxygen outer 3PE: Polyethylene and epoxy have excellent corrosion resistance, but each has its own advantages. Polyethylene is a thermoplastic material with good flexibility and resistance to bumps. Due to its non-polar molecules, it has poor adhesion to steel pipes; Epoxy resin belongs to polar molecules and has hydroxyl groups. At a certain temperature, it is prone to react with steel pipes and has strong adhesion. However, due to its thermosetting nature, it is not resistant to bumps. Therefore, the combination of the two materials belongs to the current anti-corrosion industry * combination. The plastic coated steel pipe industry has evolved from the early use of inner and outer polyethylene to inner and outer epoxy due to adhesion issues, but the outer epoxy layer is not resistant to bumps. Later, it developed into the third generation of inner epoxy outer polyethylene, but there are still adhesion issues when a single layer of polyethylene is directly combined with the steel pipe. It has been upgraded to the current fourth generation anti-corrosion inner epoxy outer three-layer structure polyethylene.

　　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.
