2014年1月6日,由宝石机械公司主持研发的“海洋立管共振弯曲疲劳试验装置”完成隔水管全尺寸疲劳试验。这表明国家工程中心首个试验平台调试完成,同时这也是国内首台大直径钢管全尺寸高速疲劳试验设备。按照计划,国家工程中心将建成三个试验平台,海洋立 January 6, 2014, developed by the Gem Machinery Company “marine riser resonance bending fatigue test device ” to complete the full-size riser fatigue test. This shows that the commissioning of the first test platform of the National Engineering Center was completed and this is also the first full-scale high-speed fatigue test equipment for large-diameter steel pipe in China. According to the plan, the National Engineering Center will build three pilot platforms for maritime legislation
