Feeding Test on Impressed Current Cathodic Protection for City Natural Gas Pipelines
-
摘要: 开展了现场馈电试验, 通过测量管网的管/地自然电位、管/地极化电位、地床电位梯度、接地电阻以及非保护区管线电位变化情况, 确定了阴极保护所需的电流密度为10 mA/m2。试验结果验证了该市使用深井阳极技术对燃气管道阴极保护的安全性、科学性和可行性。Abstract: Feeding test on impressed current cathodic protection for natural gas pipeline had been conducted in the urban area of a northwest city. Here were tested the measurement parameters including the pipe/ground natural potential, the pipe/ground polarization potential, pipeline electric potential gradient, ground resistance and non-protected pipeline potential. The minimum current density required by cathodic protection was 10 mA/m2. All the results have verified the safety, scientificity and feasibility of using deep well anode technology for city natural gas pipeline.
