摘　　要：输送低温原油的地面站场管道表面夏季会产生大量冷凝水,从而引发保温层和防腐涂层失效问题。通过对塔河输油站地面管道冷凝水腐蚀原因,如当地气候、管输介质以及设计方案等进行深入分析,发现传统的环氧类防腐涂层与无机纤维类绝热结构不符合塔河输油站地面管道的防腐与绝热要求。结合超疏水技术和传热学原理,根据当地气候环境和管输介质,重新设计了塔河输油站内管道的防腐隔热结构。研究表明,采用具有优异耐水疏水能力的超疏水复合涂层与柔性橡塑材料的复合结构,能够使站场管道表面疏水接触角大于150°,完全杜绝绝热层内外冷凝水的产生。In summer, there will be a lot of condensate water on the surface of the station pipelines that transport low temperature crude oil, which causes problems of insulating layer failure and anti-corrosion layer failure. Through deeply analyzing the reasons of condensate water corrosion, including local weather, medium of pipe transportation and design project, it is found that the traditional epoxy anticorrosive coating and inorganic fiber insulation structure cannot meet the anti-corrosion and heat insulation requirements of＂the surf＂ace pipelines in Tahe oil transportation station. Combined with the super-hydrophobic technology and heat transfer theory, and according to the local weather and medium of pipe transportation, a new anticorrosive and heat insulation structure is redesigned. Research shows that the surface of＂pipeline can get a hydrophobic contact angle over 150° with no condensate water in or out of the heat insulation layer by using the complex structure of-super-hydrophobic composite coating with superior hydrophobic and water-tolerant ability and flexibility rubber plastic material.
