利用模糊综合评判方法评价“管中管”管道腐蚀程度

To Use Fussy Integrated Evaluation Method for Appraisal Pipeline Corrosion of "Pipe in Pipe"

对“管中管”输油管道的腐蚀程度进行定量评价是全面了解管道腐蚀情况的基础,是对管道进行剩余强度评价、剩余寿命预测以及可靠性分析的依据。提出了利用模糊综合评判方法对“管中管”输油管道进行腐蚀程度评价的具体方法,通过工程实例验证了该评价方法的实用性。

To quantitative appraisal for corrosion of 'pipe in pipe'in oil transmission pipeline is the foundation to well known pipeline corrosion and the basis of residual strength appraisal,residual life forecast and reliability analysis for pipeline. It puts forward the specific method for corrosion appraisal of oil transmission pipeline by adopting fussy integrated appraisal method. It validates the practicability of this appraisal method through project example.
