摘　　要：通过提高我国现行输气管道设计及试压标准,并结合实施高强度水压试验,不仅可以提高管道输量,而且可以提高管道建设的总体水平,使输气管道在一个更加安全和经济的环境下运行。将我国国家标准和美国国家标准的相关条款进行了对比,分析了提高标准后可获得的增输量和通过高强度水压试验可获得比现行标准更多的安全余量,提出了对相关条款的修订建议。Improving China's present design and pressure-testing standards of natural gas pipelines,combinedwith high-strength hydraulic tests,not only the outputs of the pipelines can be increased,but also the wholelevel of pipeline construction can be improved,so that the natural gas pipelines can be operated under saferand more economic conditions.In the paper,relevant items of China's National Codes are compared withthat of American Codes and analysis on output increment and safer margin,which can be obtained afterimproving the present design standards and using high-strength hydraulic tests,are also carried out andsuggestions for emending relevant items are provided.
