地下埋设的金属管线,由于施工质量差,管理不善,尽管采取了防腐措施,仍然会产生漏油、漏气,甚至发生重大事故,造成重大经济损失并污染周围环境。因此,建立地下管线腐蚀情况调查及测试方法具有重大的经济价值和科学意义。 本文通过热电厂的10公里输重油管线涂层的地面检测,管线周围土壤理化性质的分 Due to the poor quality of construction and poor management, underground metal pipelines buried underground still cause oil spills and gas leaks, even major accidents, causing serious economic losses and polluting the surrounding environment despite the anti-corrosion measures taken. Therefore, the establishment of underground pipeline corrosion investigation and testing methods have great economic value and scientific significance. This article through the thermal power plant 10 kilometers of heavy oil pipeline coating on the ground detection, pipelines around the physical and chemical properties of soil points
