《揚(yáng)子晚報(bào)》報(bào)道：3PE防腐鋼管【勝倉(cāng)管業(yè) 高經(jīng)理13730570531  QQ：2927372564】：簡(jiǎn)單說(shuō)就是在工程要求的鋼管經(jīng)嚴(yán)密的除銹處理后，在外壁做上3PE（3層結(jié)構(gòu)聚乙烯）防腐介質(zhì)的管道。3PE防腐是目前為先進(jìn)、為成熟的外壁防腐技術(shù)。具有防腐性能好，使用壽命長(zhǎng)等優(yōu)點(diǎn)（youxiu的生產(chǎn)廠家生產(chǎn)的3PE防腐鋼管使用壽命能達(dá)到50年），廣泛使用于天然氣輸送、石油輸送、供熱、制冷等項(xiàng)目工程中。美國(guó)腐蝕工程師協(xié)會(huì)在1993 年的年會(huì)論文中曾這樣指出：“正確涂敷的防腐蝕層應(yīng)該為埋地構(gòu)件提供99％的保護(hù)需求，而余下的1％由陰極保護(hù)提供”， 這說(shuō)明了外防護(hù)層的重要性及不可取代性。有機(jī)涂層是廣泛應(yīng)用的防護(hù)技術(shù)之一。目前常用于鋼質(zhì)管道保護(hù)的外防腐層有以下幾種：石油瀝青防腐層、環(huán)氧煤瀝青覆蓋層、環(huán)氧粉末覆蓋層、煤 焦油瓷漆防腐層、聚乙烯膠粘帶防腐層、聚乙烯防腐層及3PE防腐層。而3PE防腐層因其優(yōu)異的物理機(jī)械性能、良好的耐化學(xué)腐 蝕性能、極低的水和氧滲透性和低環(huán)境污染性、防腐年限長(zhǎng)、絕緣性能高等特性在業(yè)界獲得很高的評(píng)價(jià)。

2PE/3PE anticorrosive 3PE anticorrosion: pipeline three layer PE anticorrosive structure: the first layer of epoxy powder (FBE > 100um), the second layer of adhesive (AD) 170 to 250um, third layers of polyethylene (PE) 2.5 to 3.7mm. The three kinds of materials are integrated into one, and they are firmly combined with the steel pipe to form a fine anticorrosion layer. The diameter range of the diameter of 60 ~ 1420 2PE diameter pipeline anticorrosion: two layer PE anticorrosion structure, the first layer of adhesive (AD), second layer polyethylene (PE), two kinds of materials with the thickness of each layer of the three layer PE. 3PE coating (three layer polyethylene) technology is an advanced anti-corrosion technology in late 90s from abroad its full name is the fusion bonded epoxy / extruded polyethylene protective layer structure. The 3PE anticorrosion technology combines the excellent properties of two kinds of anticorrosive coatings, epoxy coating and extruded polyethylene, and combines the advantages of epoxy coating's interface characteristics and chemical resistance with the mechanical protection characteristics of extruded polyene anticorrosive coating, which significantly improves their performance. Its characteristics: high mechanical strength, wear resistance, corrosion resistance, heat resistance, cold resistance, can be used in the 150 degree medium, in the cold zone to adapt. Therefore, the 3PE anticorrosion layer is an ideal outer protective layer for buried pipeline. According to the inspection by the authoritative department, the life of buried pipeline with 3PE anticorrosion technology can be as long as 50 years. 2PE coating (two layer polyethylene) pipe two layer PE anticorrosion structure, the first layer of adhesive (AD), second layer polyethylene (PE), two kinds of materials with the thickness of each layer of the three layer PE the same. The difference is that more than one 3PE anticorrosive epoxy powder and epoxy powder layer, good corrosion resistance and good mechanical properties, anti cathodicdisbonding strong, although it has the advantages of strict surface treatment, poor weather resistance, water absorption rate is high, but it is suitable for buried pipeline pipeline, the thickness of the coating is only 0.3 ~ 0.5 mm, with a life span of 40~50 years.
