通过测量管道对地电位、电位梯度和杂散电流方向,对成品油管线上的杂散电流进行了全面调查.结果表明,杂散电流干扰程度已经超过了标准规定的必须采取排流措施的警戒指标.为此,采取了牺牲阳极接地式排流,排流效率高于99%,并使管道达到了阴极保护
By measuring pipeline to soil potential,potential gradient and stray current direction, an investigation of stray current on an oil pipeline showed that the stray current interference was very large. Therefore, a sacrificial anode drainage was applied
