摘　　要：分析了兰成渝成品油管道内杂质的种类、变化趋势以及管内杂质对管道安全运行、输油设备、输送油品的影响。通过对管道清出的杂质进行试验测试分析,得出了管内杂质的形成原因,提出了相应的改进措施和操作建议。Lanzhou-Chengdu-Chongqing Products Pipeline was put into operation in 29 September, 2002, with total length of 1250 km,three diameters in 508 mm,457 mm and 323. 9 mm. This pipeline transports two kinds of gasoline and diesel on the batch transportation way with transportation capacity of 500×104 t/year and reaches the design capacity in 2005. The pipeline has 16 pumping stations,47 block valve rooms and 15 offtake stations. The pigging operations for the pipeline have been carried out since its commissioning. The pigging results show that mud, sands, rust and welding slag as well as other solid substances are main impurities,which plug the filter,abrade pipeline/equipments and deteriorate the products oil. The experiment and analysis on the origin of foreign substances are made and improvement countermeasures against the impurities are worked out based on the test results.
