The invention provides a hydrogen pipe coupling device with enhanced internal sealing. In order to enhance the sealing properties of a coupling for hydrogen pipes, a coupling for coupling multi-walled pipe segments (22.1, 22.2) is proposed, which is equipped with an inner seal (38) and an outer seal (40), and pressing means (27, 27.1, 27.2) for pressing the pipe segments together. According to the invention, the hydrogen pipe coupling (10) comprises at least one spring element (50, 50.1, 50.2) which is designed to exert a pre-pressing force on the inner seal (38) in addition to the pressing force of the pressing device (27, 27.1, 27.2).
具有增强的内部密封性的氢气管联接装置。为了增强用于氢气管的联接件的密封性,提出了一种用于联接多壁管段(22.1,22.2)的联接件,该联接件配备有内密封件(38)和外密封件(40),以及将所述管段按压在一起的按压设备(27,27.1,27.2)。氢气管联接装置(10)包括至少一个弹簧元件(50,50.1,50.2),该至少一个弹簧元件被构造用以:在按压设备(27,27.1,27.2)的按压力之外,还将预按压力施加到内密封件(38)上。
