The invention provides a natural gas pipeline corrosion failure time prediction method and device. The method comprises the following steps: determining pipeline parameters influencing the pipeline corrosion failure time by establishing a pipeline corrosion failure equation; selecting environmental parameters influencing the corrosion failure time of the pipeline; screening the pipeline parameters and the environment parameters based on correlation; and by taking the screened parameters as input variables and the corrosion failure time as output variables, constructing a prediction model, and predicting the corrosion failure time of the pipeline by using the trained model. According to the method, the pipeline parameters influencing the corrosion failure time are determined by establishing the pipeline corrosion failure equation, the environmental parameters of the pipeline are increased, and the parameters screened based on correlation serve as the input variables of the prediction model, so that the predict
