据报道,我国某油田埋地管线中,集油管线年孔穴腐蚀速度为2.4毫米,供水管为1.8毫米,水管管线内壁腐蚀速度为1.8毫米,漏油和漏气事故不断出现,在经济上造成的损失极大。实践证明,新的管线采取防腐措施,在经济上是合算的,特别是管道内壁防腐,不仅有防腐及抗磨损作用,而且还可减小阻力,增加流量,降低压缩机泵的投资和管线的维修费用,并达到节能目的。因
It is reported that in a buried pipeline in an oilfield in China, the annual corrosion rate of the oil collection pipelines is 2.4 millimeters, the water supply pipe is 1.8 millimeters, and the corrosion rate of the inner wall of the water pipelines is 1.8 millimeters. Oil spills and air leaks continue to occur economically The great loss. Practice has proved that the new pipeline to take anti-corrosion measures, economically cost-effective, especially the pipeline wall corrosion, not only corrosion and wear resistance, but also reduce resistance, increase flow, reduce compressor pump investment and pipeline Maintenance costs, and achieve energy-saving purposes. because
