Description :

　　Introduction to TPEP anti-corrosion steel pipe production process. 1. Compared with traditional electric furnace heating methods, medium frequency heating has a higher conversion rate and effectively saves electricity for steel pipes. By using medium frequency heating, the heat in the steel pipe is dissipated from the inside out, making the heating temperature more uniform and effectively ensuring the curing of the epoxy coating. 2. Single layer polyethylene adopts the technology of internal spraying and external spraying of epoxy powder and external spraying of polyethylene powder, which is called curtain method or coating process. It uses intermediate frequency heating to use the waste heat of the pipe to cure both at the same time, without the need for separate coating and curing. 3. The three-layer structure polyethylene adopts fusion bonding and winding technology, and the inner wall adopts thermal spraying epoxy powder anti-corrosion method. The powder is uniformly coated on the surface of the pipe body after high-temperature heating and fusion bonding. The outer coating is applied using high-pressure extrusion winding technology, greatly improving its density. The coating is tough, wear-resistant, and has excellent impact and bending resistance, which can effectively prevent mechanical damage during construction and damage to plant roots and soil environmental stress during use.

　　TPEP performance characteristics: The TPEP anti-corrosion process (inner EP and outer 3PE) for large-diameter water transmission pipelines combines thermosetting epoxy resin powder coating with polyethylene characteristics and processing technology. The three-layer structure polyethylene coating and fusion bonded epoxy powder coating technology are cleverly combined to provide a solution for 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 Chengyuan 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).
