In this paper,based on the statistics of the fault data of large centrifugal compressor units in the national pipeline network from 2006 to 2022,the data were cleaned and the centrifugal compressor system was divided into multiple subsystems for probability statistics,including having the empirical distribution fitting and testing implemented through the historical fault data to establish a calculation model for the fault data of both centrifugal compressor and its components.The results show that,the process system complies with the log-normal distribution and the others obey the double-parameter Weibull distribution.All the computational models developed have confidence intervals above 95%.
