TPEP anticorrosion process (inner EP and outer 3PE) is a combination of thermosetting epoxy resin powder coatings and polyethylene properties and processing technology, the three-layer structure of polyethylene coating and fused epoxy powder coating technology skillfully combined, for buried steel pipe corrosion protection provides a high-quality program, the inner wall fused epoxy resin powder (FBE) anticorrosion, to solve the problem. The problem of internal corrosion of pipes is characterized by small roughness, smooth inner wall and good hydraulic performance. Through the analysis of design examples, it is concluded that compared with the same pipe diameter, the loss of pipeline with epoxy coating on inner wall can be reduced by more than 30%; under the same flow rate, the pipe diameter can be reduced by one stage, thus reducing the cost and energy consumption. It has been widely used in the market as the main product of large diameter water delivery pipeline with large diameter. It has been applied in the supporting projects of the South-to-North Water Transfer Project, the APEC Summit, the ecological water supply of Yanqi Lake in Huairou, Beijing, and the national key projects of Chongli ski resort in the bidding venue of the Winter Olympic Games.

Reliability: Large-caliber water supply pipe, once tube burst or leakage accident occurs, waste is great, and the impact on residents is great. Considering the quality of pipe material, bearing capacity, and reliability of connection. First choice - steel pipe anti-corrosion 2, safety: the quality of tap water standards have been close to international standards, residents of the water quality requirements are increasingly high, the inner coating for drinking water grade pipes to prevent secondary pollution. Preferred - food-grade epoxy powder 3, energy-saving: water supply network operating costs are power consumption, long lines, reduce network operating energy consumption factors, preferential selection of pipes with small roughness coefficient. Preferred - hot-melt epoxy powder, smooth, not easy to scale 4, economy: the cost of the pipeline should be considered from the perspective of the whole cycle, not only to consider the cost of pipe, but also to consider the installation and construction of pipe, subsequent operating costs and service life.首選——TPEP防腐鋼管TPEP防腐鋼管又稱外3PE防腐內(nèi)熔結(jié)環(huán)氧粉末復(fù)合鋼管，防腐鋼管母材包括螺旋焊管，直縫焊管，無縫鋼管等，鋼管外壁采用纏繞聚乙烯的3層PE結(jié)構(gòu)防腐技術(shù)，先在外壁底層涂覆環(huán)氧樹脂，中間層是膠黏劑，起粘合作用，最后在外層緊密纏繞聚乙烯皮，聚乙烯防腐層具有極高的密封性，良好的耐腐蝕和耐沖擊性，PE吸水率低（低于0.01％）�？捎行Х乐够驕p緩在運(yùn)輸與使用過程中發(fā)生化學(xué)或電化學(xué)反應(yīng)發(fā)生腐蝕現(xiàn)象的鋼制管道。根據(jù)我國統(tǒng)計數(shù)據(jù)，每年國內(nèi)的鋼管腐蝕直接經(jīng)濟(jì)損失2800多億，當(dāng)前全球每年因鋼管腐蝕損失高達(dá)5000億美元。

TPEP anticorrosive steel pipe can effectively prevent or slow down corrosion, reduce the operation cost of steel pipe, and prolong the service life of steel pipe. Thermal spraying epoxy powder is used in the inner wall of the steel pipe. The powder is melted and evenly coated on the inner surface of the pipe by high-frequency heating. The coating is smooth, clean and pollution-free. The standard of use is up to the national food grade. TPEP anticorrosion technology makes the inner and outer walls of the pipeline reach the best anticorrosion effect and plays the best protection role to the main body of the steel pipe. This kind of anticorrosion treatment is the most advanced integral anticorrosion treatment technology for steel pipe at home and abroad. At the same time, it is also the best choice of anticorrosive treatment for high demand projects at home and abroad. The product is suitable for pipeline transportation engineering under various conditions. It is a revolution of traditional pipeline products, and is the best choice to replace steel tube concrete pipe, ductile iron pipe, PE pipe and other traditional products.
