Abstract: Taking the four gas compressor stations, under the jurisdiction of Henan-Anhui Management Office, PetroChina West-to-East Gas Pipeline Company, as an example, investigation and analysis are made to determine the impact of outlet temperatures of gas compressor station on the local crop growth around the pipeline. It is pointed out that the traditional method to reduce the outlet temperature by means of changing the operating mode of cooling fan has shortcomings. A new method to reduce the outlet temperature of gas compressor station by means of applying thermal insulation has been proposed to mitigate the impact on the local crop growth. The pipeline insulation is modeled and the best thickness of insulation is turned out from calculation as 0.23 m. It is known from comparison and analysis that the expenses for claim compensation to the local peasants in three years for each gas compression station are more than the cost of insulation addition. Finally, a rational suggestion is proposed on the procedures for insulation application in the existing and newly-built gas compressor stations.
