| Abstract: | Because the oil refining pipelines under high temperature always get corroded badly and many fire accidents happened,the reasons that caused corrosion of the refining pipeline were researched according to the character of the easy-corrosion.The measuring technology to the thickness of the easy-corrosion pipelines in the refinery under the high temperature was studied.After simulating experiments,the mathematics changing model of the tested data,the computing method of corrosion speed and the residual period of validity of pipeline were formulized.Firally,practically applied the technology in the refinery and had successfully predicted hidden troubles of corrosion. |
