摘要
原油输送管道经过一定时间的使用，由于原油中粘性分子在管壁的沉积，造成实际输油管径减少，压降增大，大大增强了系统能耗。通过分析原油输送管道结蜡情况得出结论：采用机械清管方法可以清除管内结蜡，保证管路正常输送。在阐述机械清管的工艺设计、器具选择和操作规程的基础上，进一步对器具的维护和清管中的注意事项进行简要说明。
After oil pipeline was used for a period of time,viscidity molecule in crude oil would deposit on pipe wall and therefore pipe wall was reduced and pressure drop and energy consumption were increased.A conclusion was given by analyzing the paraffin in the internal wall of the pipeline,that is the paraffin in pipe could be cleaned by using the mechanical pigging method so as to ensure the normal pipeline transportation .Points for attention of equipment maintenance and pigging were briefly introduced based on describing the process design 、the unit selection and operation specification of mechanical pigging .
