天然气管道泄漏数据

The leakage data of the natural gas pipeline comes from the simulated leakage device of the pressure pipeline. The pipeline material is seamless steel pipe, the outer diameter of the pipeline is 108mm, the wall thickness of the pipeline is 4.5mm, and the length of the pipeline is about 100m. According to the specifications of the air compressor and air storage tank (the maximum allowable pressure is 2Mpa) and the standard of high-pressure and sub-high-pressure pipeline gas transmission pressure, the selected experimental pressure range is 0.5Mpa to 2Mpa. The leak diameters on the experimental pipeline are 1mm, 2mm, and 4mm, respectively, and the collection rate of pipeline leakage data is 100kHz.

本天然气管道泄漏数据取自压力管道模拟泄漏装置。试验所用管道材质为无缝钢管，外径108mm，壁厚4.5mm，管长约100m。结合空气压缩机与储气罐的技术参数（最大允许压力为2MPa），以及高压及次高压管道输气压力标准，本次试验选取的压力范围为0.5MPa至2MPa。试验管道的泄漏孔径分别为1mm、2mm与4mm，管道泄漏数据的采集速率为100kHz。
