摘要：
The production of aluminum can produce large dynamic stray currents in the earth surrounding the production plant. When coated pipelines that are not grounded pass through the dynamic stray current area, they can realize failures at accelerated rates, even with traditional cathodic protection systems in operation. This article tracks a coated 20-in. (51-cm) natural gas pipeline installed near an aluminum production facility and the stray current mitigation design installed to overcome the accelerated failure problem. Other types of stray current mitigation have been attempted in this same area without similar success.
