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.
