By constructing a pipeline network simulation model,the minimum outbound temperature of the station and the limit low throughput of the pipeline are simulated under different transport volumes and ground temperature conditions,and the lean operation mode of the pipeline system is explored.The results show that the lower the ground temperature is,the higher the minimum exit temperature is,and the higher the limit low throughput is.The research results can be used to guide the actual operation of the pipeline and provide ideas and references for the lean operation of the pipeline in the future.
