摘要
介绍了埋地燃气管道防腐蚀措施及沥青外防腐蚀层老化状况评价标准,以一燃气管道某管段为实例,通过应用马尔可夫链理论,阐述了利用转移概率矩阵对沥青外防腐蚀层老化状况进行预测的方法,从而为确定外防腐蚀层的合理维修周期提供了理论依据。
The buried gas pipeline corrosion protection measures and evaluation criterion for coating degradation with asphalt are introduced, Taking a segment of gas pipeline as example, by using the theory of Markov chain, the application of transition probability matrix in prediction for coating degradation with asphalt is illustrated, which provides a basis for determining external anticorrosive coating maintenance cycle.
