Study on corrosion rate of buried gas steel pipeline in Nanjing based on the GM(1,N)optimization model

摘要：

　　In view of the complex and fuzzy corrosion mechanism of buried gas steel pipelines,the grey correlation analysis method is used to find out the main factors affecting the corrosion rate and sort them by association degree.And then the corrosion rate model of buried natural gas steel pipeline is established based on GM(1,N)model and OGM(1,N)(an optimization method for the GM(1,N))model.Results show the main factors affecting the corrosion rate of buried steel pipelines in Nanjing are service life,pipeline protection measures,soil resistivity and stray current.Compared with the GM(1,N)model,the accuracy of OGM(1,N)model is greatly improved.OGM(1,N)model can effectively simulate pipeline corrosion rate considering multiple factors,which has a certain reference value for the study on residual life of buried gas steel pipelines.
