中国首次X90钢管全尺寸天然气爆破试验获成功

原标题:中国首次X90钢管全尺寸天然气爆破试验获成功

新华社乌鲁木齐12月16日电(记者熊聪茹、顾煜)一朵巨大的“蘑菇云”16日在新疆哈密市东南方100多公里的中国石油管道断裂控制试验场升起。这标志着中国首次X90钢管全尺寸天然气爆破试验首爆成功,进一步提升了我国在高钢级、大口径、高压力管材断裂控制方面的研究水平。

此次试验由中国石油西部管道公司、石油管工程技术研究院、中国石油规划总院等组成的科研团队主导,项目属中国石油集团公司重大专项“第三代大输量天然气管道工程关键技术研究”中的一项内容。

据承担此次试验的石油管工程技术研究院介绍,试验同期开展了基于管道断裂控制试验场的天然气管道爆破(爆炸)冲击波、地震波、热辐射等危害效应研究,其结果将为我国大输量、高压力、高钢级天然气管道建设和安全运行提供重要技术支撑。

随着天然气需求与日俱增,采用大口径、高钢级、高压力长输管道已成为世界天然气管输技术的主流,由此带来的天然气管输安全问题受到越来越多关注,而全尺寸气体爆破试验是目前获得管道性能数据的最先进技术手段。

长期以来,我国全尺寸气体爆破试验只能委托其他国家进行,费用高,周期长,还无法获取部分关键实验数据。2012年,中国石油将管道断裂控制试验场列为重大科技专项重点现场试验课题,并于2015年10月在新疆哈密建成我国首个管道断裂控制试验场,研发了钢管全尺寸爆破试验技术,填补了国内空白。一年多来,这个试验场已先后实施两次X80钢管爆破试验,为中俄东线天然气管道建设提供了有力技术支持。(完)
