Development Direction of Pipeline Corrosion Research on Oil Refining and Chemical Enterprises

Abstract

The corrosion behavior of refinery due to severe corrosive environment was investigated in the present study, and the analysis was focused on the guiding of the corrosion into a site where is near the ground, easy to change, have low risk and so on. The corrosion parts were analyzed to study the influences of the corrosion pipe in the whole systems. Some suggestions were proposed to choose the corrosion site that can happened. By using the developed method in this study the low risk position of pipeline as a sacrificial location can be found, and then taking it as the priority corrosion place under the control of switchable subline. It is therefore to shut down for maintenance of whole pipeline, and to easily replace the corrosion parts without stop all. The serious corrosion of refining pipeline system can consequently be reduced and removed, thereby to make the long-cycle operation of refining factory be realized.
