接続装置の実現が強く要望されていた。However, when it comes to large oil production facilities, the number of pipelines that need to be connected increases. Therefore, it is an extremely difficult task to connect these many pipelines at the same time with the same degree of precision. A high degree of precision is required to connect pipelines under high-pressure conditions.6 In particular, when connecting multiple pipelines installed on upper and lower structures at the same time, There has been a strong demand for a connection device that can automatically absorb differences in machining of center positions and assembly errors between pipelines to some extent.
そこで、本発明は前記要望に応えるためになきれたもの
