由中石油管道局机械公司自主开发研制,目前国内最大直径、最高压力快开盲板与绝缘接头——压力12.6 MPa、直径1550mm环锁型快开盲板和压力12MPa、直径1400mm整体式绝缘接头,近日通过中国特种设备检测研究院的技术检测。这标志着我国油气管道关键设备国产化又一次新突破。据相关人士介绍,快开盲板与绝缘接头分别是中石油科技重大专项研究课题《油气管道关键设备国产化》和《第三代大输量天然气管道工程关键技术研究》中的一项。此两项产品的成功研制,是中石油管道局高压力、大口径
By the PetroChina Pipeline Bureau Machinery Company independently developed, currently the largest diameter, the highest pressure quick open blind and insulated joints - pressure 12.6 MPa, 1550mm diameter ring-lock quick-opening blind and pressure 12MPa, diameter 1400mm monolithic insulation connector, Recently passed the China Special Equipment Testing Institute of Technology testing. This marks another breakthrough in the localization of China’s key equipment for oil and gas pipelines. According to the relevant personage introduction, the quick opening blind and the insulation joint are respectively one of the research topics of “Key Equipment for Oil and Gas Pipeline Localization” and “The Key Technology Research of the Third Generation Large-Capacity Natural Gas Pipeline Project” in the major project of petroleum science and technology. The successful development of these two products is the high pressure and large caliber of PetroChina Pipeline Bureau
