[Abstract]:In this paper, the scheme of natural gas gathering and transportation trunk line of Yanchang Gas Transmission Station is studied to ensure the smooth operation of the gas pipeline project and meet the requirements of downstream users for natural gas consumption, so as to promote the efficient utilization of natural gas. Optimize the energy structure and promote the construction of low-carbon cities. First of all, according to the principle of line selection, the relevant standards and the field investigation of the geographical location of the first and last stations of the project and the geographical situation of the areas along the line, through the analysis of the situation along the route, social support, pipeline safety management and technical feasibility, The recommended route scheme is determined, and then the pipeline laying and line ancillary facilities are determined. According to the principle of gas supply and distribution, the relevant standards and the actual situation of the project, the gas supply and distribution scheme is determined. The process calculation of the pipeline is carried out by using the gas pipeline simulation calculation software PipelineStudio of British ESI Company, and the gas transmission process scheme is determined. Then the adaptability analysis of the pipeline is carried out, and the results show that the gas transmission process scheme of the project can meet the requirements of pressure and flow. The steel grade, steel pipe type, line pipe scheme and the total amount of steel needed are determined by calculation, and the strength and stability of the pipeline are checked. According to the principle and standard of station setting, the setting scheme of field station is determined, and the technology of field station, the selection of equipment and the pipe of field station process are determined. Through analysis and research, the external anticorrosion and cathodic protection scheme of line pipeline, station yard and valve chamber process pipeline and equipment are determined, and the heat preservation scheme of pipeline and equipment in the station is determined.
