摘要
管道水平定向穿越完成后,涂层经常容易受到各种形式的损伤。文中参考NACE TM0102-2002地下管道涂层电导率测试标准,提出了一种方法,通过计算涂层的归一化比电导率,对水平定向钻穿越完成后的管段涂层性能进行测试与评价。多次现场测试结果表明:该方法可有效用于对穿越完成后的涂层性能进行评价,并同时指出了该方法的局限性。
The pipeline coating can be damaged in various forms after application of horizontal directional drilling technology. The paper presents a method of calculating the electrical conductance of specified coating on underground pipelines in reference to NACE TM0102 -2002 measurement of protective coating electrical conductance on underground pipelines. Field tests prove that this method can effectively test and evaluate the coating quality after application of horizontal directional drilling. Meanwhile,the limitation of this method is also listed.
