Selection of technical and technological parameters of pumpdown product from the cavity plot of oil pipeline

摘要

The calculation formulas for determination of operating efficiency of product removal from pipe-line cavity by pump exhausting depending on section area and pressure head of a relieved pipe line so as to provide maximum possible operating efficiency of product removal from the pipe line. The obtained results can be used for breakdown maintenance of oil-trunk pipelines and overhaul of oil-products pipelines.
