Abstract

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 prediction precision of the prediction model can be obviously improved.

Description

technical field [0001] The invention relates to the technical field of corrosion prediction of natural gas pipelines, in particular to a method and device for predicting corrosion failure time of natural gas pipelines. Background technique [0002] The natural gas pipeline is an integral part of the natural gas pipeline network. Due to the corrosive gases such as hydrogen sulfide and carbon dioxide contained in natural gas products, and the influence of environmental factors on pipelines, pipelines are easily corroded, resulting in damage and failure. The corrosion of natural gas pipelines is one of the main factors affecting the safety of gas in my country. Urban gas is related to the national economy and the people's livelihood. Pipeline corrosion will not only affect the life of natural gas pipelines (the time from being buried underground to failure due to corrosion, that is, the corrosion failure time ), forming potential safety hazards, and even causing safety accident...
