| Abstract: | The natural gas in northeast Sichuan contains much H2S,which makes it easy to cause SSC,HIC and electro-chemical corrosion in the gas line,thus affecting the safe operation of the gathering line.By analyzing corrosion factors,such as H2S content and CO2 content,the delivery pressure,and the compositions of pipe materials,etc,this paper use OLI Corrosion Analyzer to simulate the working condition of a pipeline in northeast Sichuan.This paper might be helpful for selection of preventive measures against corro... |
