打开铺设已久的30B海底原油管线进行检查，发现管内壁存在大面积腐蚀。因此使用添加新研制的特殊硅烷系列耦合剂的玻璃乙烯基脂树脂，采用“CEC式防腐涂层施工法”进行内防腐衬里施工。30B内防腐衬里管在使用一年后打开检查，结果发现该衬里达到了最初设计的20年的使用寿命，并且计划在第4年和第8年继续检查。此外，CEC树脂衬里管的静电特性的实际规模基础实验结果也发现CEC树脂衬里材料也产生静电，其程度与配管用碳钢钢管大致相同，与普通钢管一样可输送油品。本文将介绍这些配管内衬里用多层防腐材料的特征，以及SBM管线的大口径、长距离管线的防腐深层施工实例。
Open the long-laid 30B seabed crude oil pipeline inspection and found that the inner wall of the pipe there is a large area of corrosion. Therefore, the use of newly developed series of special silane coupling agent of glass vinyl resin, the use of “CEC anti-corrosion coating construction method” for the construction of anti-corrosion lining. The 30B inner liner was opened for inspection after a year of use, and found that the liner had reached the initial 20 year service life and was scheduled to be inspected in the 4th and 8th year. In addition, the experimental results of the actual scale of the electrostatic properties of CEC resin lined pipe also found that CEC resin lined material also produced static electricity in the same degree as that of carbon steel pipe for piping. Like ordinary steel pipe, oil can be transported. This article will introduce the characteristics of these pipes with multiple layers of anti-corrosion materials, as well as SBM pipelines large-diameter, long-distance pipeline corrosion deep construction example.
