|
摘要
开展X90钢级高压气体管道爆炸模型实验,初步探索并解决了管道爆炸实验的关键技术问题,为管道全尺寸爆破实验提供数据和方法支撑。结果表明:实验方法及测试仪器的选择可靠有效,解决了管道封堵、初始裂纹引入、传感器安装及密封、动态参量测试以及测试系统构建等关键技术问题;填充空气的运行压力为12.3MPa的X90钢管裂纹最大扩展速度约为248m/s,临界止裂压力约为4.5MPa,临界止裂速度约为100m/s;裂纹止裂器止裂效果明显,可进一步优化其安装位置并适当加宽加厚,进一步提高止裂效果。
Explosion model experiment of the X90 steel grade high-pressure gas pipeline was conducted to preliminarily solve the key technical problems of pipeline explosion experiment,provide data and methods for full-scale explosion experiment.Results showed that the experiment methods and instrument was reliable and effective,the key technical problems of pipe plugging,initial crack bringing in,the sensors installation and sealing,dynamic parameters testing and construction of testing system were solved.When the operating pressure was 12.3 MPa,the biggest crack propagating speed of air-filling X90 pipeline was about 248m/s,its critical crack-arrest pressure was about 4.5MPa and critical crack-arrest speed was about 100m/s.The effect of crack arrester was obvious,and to improve the crack-arrest effect,the installation position should be further optimized and the arrester should be widened and thickened properly.
