随着公共基础设施建设的加快,如电气化系统、高压输电系统,这些系统产生的电流使管道受到日益严重的交流干扰,我国许多埋地钢制管道就受到了不同程度的影响。本文主要介绍了交流干扰对管道的影响和国外的交流腐蚀的指标,总结了一些重要的交流干扰防护结论,简述了埋地钢制管道交流干扰防护的设计施工方法,并提供一些可供参考的意见和建议。 With the acceleration of public infrastructures, such as electrification systems and high-voltage transmission systems, the current generated by these systems has caused increasingly serious interference with the pipelines. Many buried steel pipelines in our country have been affected to varying degrees. This article mainly introduces the influence of AC interference on pipeline and AC corrosion index in foreign countries, summarizes some important AC interference protection conclusions, briefly describes the design and construction method of AC interference protection for buried steel pipeline, and provides some references for reference Comments and suggestions
