Corrosion Investigation on Tubular Goods for Pipeline Monitoring and Design
Gathering pipeline failure has been detected in a gas field in western China in 2009. It presents that corrosion predication and control is a key problem to avoid frequently excavating. Therefore, corrosion of 20G, 20#, 15CrMo and 16Mn steels in the stimulated environment were investigated in order to evaluate corrosion risk of the buried pipeline and design the new pipeline. The influence of environmental factors to the materials was discovered by orthogonal experiment. It is found that temperature, pH, HCO33- and Cl- are the most important factors though their subsequences are difference for the four steels. The electrochemical method, XRD and SEM were used to provide evidences to the corrosion difference. Corrosion monitoring is designed on the basis of the laboratory results. And the principle of materials selection is scheduled by considering the corrosion resistance and economical management target.
