输气站腐蚀行为分析

Analysis of Corrosion Behaviour at Gas Transmission Stations

由于胜利油田输气管线中常会存在积液,且其成分多为CO_(2)与H_(2)S,其腐蚀规律难以掌握。本文针对该条件下管道的腐蚀行为进行了分析,并针对腐蚀条件进行了平行实验,确定该条件下的腐蚀影响因素,为后续的腐蚀防治提供前期依据。

As there are often accumulations of liquid in the gas transmission pipeline of Shengli oilfield,and its composition is mostly CO_(2) and H_(2)S,its corrosion law is difficult to grasp.In this paper,the corrosion behavior of the pipeline under this condition is analyzed,and parallel experiments are conducted for the corrosion condition to determine the corrosion influencing factors under this condition and to provide the preliminary basis for the subsequent corrosion prevention and control.
