农村排水用3pe防腐钢管

农村排水用3pe防腐钢管从根本上了防腐钢管的防腐效果，然后进行下一道工序：胶黏剂三层结构聚乙烯防腐层(3PE)综合了熔结环氧粉末涂层和挤压聚乙烯两种防腐层的优良性质，将熔结环氧粉末涂层的界面特性和耐化学特性，与挤压聚乙烯防腐层的机械保护特性等优点结合起来，从而显著改善了各自的性能。因此作为埋地管线的外防护层是非常的。据有关资料介绍，三层PE可使埋地管道的寿命达到 50年，目前，在国际上被认为是的管道外防腐技术。在我国，三层PE已率先在石油天然气系统得到应用。我国已建成的陕京天然气管道及库鄯输油管道，近西气东输近4000公里管道均采用了三层PE外防腐涂层。在天津市，陕气进津67公里高压管道、外环线30公里高压天然气管道、陕京线地下储气库122公里管线也是采用的三层PE。 三层结构聚乙烯防腐层（3PE）综合了熔结环氧粉末涂层和挤压聚乙烯两种防腐层的优良性质，将熔结环氧粉末涂层的界面特性和耐化学特性，与挤压聚乙烯防腐层的机械保护特性等优点结合起来，从而显著改善了各自的性能。因此作为埋地管线的外防护层是非常的。据有关资料介绍，三层PE可使埋地管道的寿命达到50年。
The anti-corrosion effect of 3PE anti-corrosion steel pipe for rural drainage is guaranteed fundamentally. Then the next process is carried out: the adhesive three-layer structure polyethylene anti-corrosion coating (3PE) combines the excellent properties of fused epoxy powder coating and extruded polyethylene coating. The interface characteristics and chemical resistance of fused epoxy powder coating are studied. It combines with the advantages of extruded polyethylene coating such as mechanical protection characteristics, thus significantly improving their respective properties. Therefore, the outer protective layer as a buried pipeline is very superior. According to the relevant information, three-layer PE can make the life of buried pipelines up to 50 years. At present, it is considered as the most advanced external anticorrosion technology in the world. In China, the three tier PE has been the first to be applied in petroleum and natural gas system. The Shaanxi-Beijing natural gas pipeline and the Kushan-Shanxi oil pipeline, which have been built in China, recently adopted three layers of PE external anticorrosive coating for nearly 4000 kilometers pipeline of West-East Gas Pipeline, a national key project. In Tianjin, 67 km high-pressure pipeline for Shaanxi gas entering Tianjin, 30 km high-pressure natural gas pipeline for outer ring line and 122 km pipeline for underground gas storage of Shaanxi-Beijing line are also three-layer PE. Three-layer structure polyethylene anticorrosion coating (3PE) combines the excellent properties of fused epoxy powder coating and extruded polyethylene coating. It combines the interfacial characteristics and chemical resistance of fused epoxy powder coating with the mechanical protection characteristics of extruded polyethylene coating, and improves their respective properties significantly. Therefore, the outer protective layer as a buried pipeline is very superior. According to the relevant information, the life of buried pipelines can reach 50 years by three layers of PE.
