The natural gas pipeline, as the city's main infrastructure, has been given priority to the development in the domestic urban construction, and provides a strong guarantee for improving the environmental services of the city district, creating more harmonious and happy living space for the human, city, and the Earth. In order to ensure gas supply security, we must take the necessary measures to improve the quality of engineering design, construction quality and the quality of operation management. Taking Zhongshan City of Guangdong Province for example, piped gas installation mode is analyzed and discussed, solutions of the segmented construction are proposed, and regulator gas supply ways are compared to provide reference and reference for the design and construction of the domestic gas pipeline.%管道天然气作为城市的主要基础设施,在国内城市建设中都得到了优先发展,为城市小区提高环境服务,创造出人与城市、人与地球更为和谐幸福的生活空间提供了有力的保障.为确保供气安全必须采取必要的措施提高工程的设计质量、施工质量和运行管理质量.本文以广东省中山市市区为例,通过对管道燃气安装模式进行分析和探讨,提出分段式施工的解决方案,并对调压供气方式进行比较选择,为国内燃气管道的设计和施工提供参考和借鉴.
