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.

Co-operation branch urgently owners, timely adjustment of the production organization plan, appropriate supplement of some staff as emergency protection, the withdrawal of skilled personnel for the vehicle escort, for the production breakthrough has laid a solid foundation.
大口徑輸水防腐鋼管的選擇及應用  1、 可靠性：供水管道口徑大，一旦發生爆管或漏水事故，浪費大， 給居民造成的影響大，考慮管材質量及承壓能力，及連接的可靠性。  首選——鋼管加防腐  2、安全性：對自來水水質的標準已靠近國際標準，居民對供水水質的要求也越來越高，內涂層為飲用水級別的管道，防止發生二次污染。  首選——內壁要求食品級環氧粉末 3、節能性：供水管網投入運行費用是耗電，線路長，降低管網運行耗能的因素，優先選用管道粗糙系數小的管材。  首選——熱熔環氧樹脂粉末，光滑，不易結垢  4、經濟性：管道的造價要從全周期的角度綜合考慮，不僅要考慮管材費用，還要考慮管材的安裝施工，其后的運行費用以及使用壽命。  Selection and application of large-caliber anti-corrosion steel pipe for water conveyance 1. 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防腐內熔結環氧粉末復合鋼管，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結構防腐技術，先在外壁底層涂覆環氧樹脂，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％）。可有效防止或減緩在運輸與使用過程中發生化學或電化學反應發生腐蝕現象的鋼制管道。根據我國統計數據，每年國內的鋼管腐蝕直接經濟損失2800多億，當前全球每年因鋼管腐蝕損失高達5000億美元。

First choice - TPEP anticorrosive steel pipe TPEP anticorrosive steel pipe, also known as external 3PE anticorrosive internal melting epoxy powder composite steel pipe, anticorrosive steel pipe base material including spiral welded pipe, straight welded pipe, seamless steel pipe, etc., steel pipe outer wall using wound polyethylene three-layer PE structure anticorrosive technology, first coated with epoxy resin at the bottom of the outer wall, the middle layer is adhesive, starting. Finally, the polyethylene coating is tightly wound in the outer layer. The polyethylene coating has high sealing, good corrosion resistance and impact resistance, and low water absorption of PE (less than 0.01%). It can effectively prevent or slow down the corrosion of steel pipeline in the process of transportation and use. According to the statistics of our country, the direct economic loss of steel pipe corrosion in China is more than 280 billion yuan every year. At present, the loss of steel pipe corrosion in the world is as high as 500 billion dollars every year.TPEP防腐鋼管可有效地防止或減緩腐蝕，降低鋼管運行成本，延長鋼管的使用壽命。鋼管內壁采用熱噴涂環氧粉末防腐方式，粉末經中頻的高溫加熱熔結后均勻地涂覆在管體內壁表面上，形成的防腐層光滑亮潔，無污染，使用標準達到國家食品級。TPEP防腐技術使管道內外壁都達到最好的防腐效果，對鋼管主體起到了最好的保護作用，這種形式的防腐處理是目前國內乃至國際上最為先進的鋼管整體防腐處理技術。同時也是國內外高要求工程項目的最優防腐處理選擇。產品適用于多種條件下的管道輸送工程，是對傳統管道產品的一次革命，是替代鋼筒砼管、球墨鑄鐵管、PE管等傳統產品的最佳選擇。

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.
