| 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NACETM0102—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。

| Abstract: | 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 limitati... |
