哈尔滨市天然气长输管道输送设计 摘 要 天然气作为一种绿色高效能源，应用越来越广泛，城市燃气的气源正由煤制气、液 化石油气向天然气转换，目前我们国家的城市燃气业务正在篷勃发展，天然气长输管道 建设项目越来越多。 本文以《哈尔滨市天然气总体规划》中所提供的哈尔滨市2008-2020 年的天然气需求 数据为依据，根据国家管道工程的标准和规范设计了哈尔滨市天然气长输管道的工程施 工项目。在建立了管道间流量与压力、管径和长度之间的函数关系后提出了提高管输能 力的途径；经过计算比较选择了储气调峰方式和管径；确定了输送工艺流程和主要站场 的工艺设备，针对哈尔滨市的地理特点，确定了长输管道的输气路线、敷设方法和自然 障碍的穿越方案及管道防腐方法；通过计算选择了合适的管道材料等级，并进行了管道 的强度计算和校核。 关键词：长输管道， 工艺流程，强度计算 Long-distance Natural Gas Pipeline Design of Harbin ABSTRACT Natural gas has been used more and more widely as a green and efficient energy. The source of fuel gas of the city is converting from coal gas, liquefied petroleum gas into natural gas. At present, our countrys city gas industries are booming and the projects of long-distance natural gas pipeline construction are becoming more and more. In this paper, based on the 2008-2020 Harbin natural gas data provided by the Overall Planning of Natural Gas in Harbin, according to the national standards and norms, designed the Harbin long-distance natural gas pipeline. Then proposed the approaches of enhancing transportation capacity after establishing the function between the flow and pressure, diameter and length; chose methods and diameter gas peak shaving; determined the transmission process and the main station process equipment. In view of the geographical characteristics of Harbin, determined the long-distance gas pipeline routes, laying methods and through obstacles methods and anti-corrosion methods; chose the appropriate level of pipeline materials by calculation. Finally, carried out the pipeline Strength calculation and checking. Key words: Long-distance pipeline, process, strength calculation
