- 摘要:
- 中俄原油管道黑龙江穿越工程中,采用俄方规范ГОСТ51164-1998《干线管道防腐要求》中所列的馈电测试方法,对水平定向钻穿越后管道外防腐层的优劣进行定量评价。结果表明,外防腐层的电阻率、阴极极化电流、管/地电位偏移等都符合要求。
Feed-current test method introduced in ГОСТ 51164-98 "Anticorrosion Requirements for Trunk Pipeline" had been used in the crossing project of Russia-China Crude Oil Pipeline for assessing the pipeline external anticorrosion coating quality after HDD crossing operation. The results showed that the electric resistivity of external coating, cathode intensified current and pipe/ground potential shift met the requirements.2012,1(1): 65-67 收稿日期:2011-10-17DOI:10.3969/j.issn.1001-2206.2012.01.020作者简介:窦宏强(1976- ),男,河北廊坊人,工程师,2000年毕业于青岛化工学院高分子材料与科学学院,从事管道防腐设计工作.参考文献:
