    Abstract: The present invention relates to a device 100 for connecting a gas-conducting conduit element 1, in particular a hydrogen-conducting conduit element, to a counterpart 2, in particular a component, comprising: at least one screw body 10, which is configured to be brought into tight engagement, in particular into gas-tight engagement, with the counterpart 2; a first seal 3, which is in the form of a valve body 3a which is configured to be brought into contact, in particular into gas-tight contact, with a valve seat 4 provided on the counterpart 2, or which is in the form of a flat seal; and a second seal 5 which operates on a sealing effect principle according to which the sealing effect is exerted or deployed irrespective of an axial displacement, in particular in an installation direction E, which is necessary for creating the sealing effect of the first seal 3.

    Abstract: Methods and apparatus enable the integrity of a liner pipe to be quickly and effectively tested in the field, while permitting rapid removal and replacement of the liner pipe if it is compromised. The liner pipe is leak tested prior to reversion, after being pulled through a host pipe to be lined via a swaging die and while the liner pipe is still under tension. If the liner pipe exhibits a leak, it can be removed from the liner pipe immediately and, importantly, before it has expanded to contact the host pipe. Leak testing apparatus includes a packer, which seals the opposite end of the liner pipe from the end which is pulled, creating a contained fluid volume upon which the leak test is performed. The leak test may be a pressure test or a vacuum test or any other suitable test.

    Abstract: Disclosed is an expansion tank having an internal cavity separated by a flexible diaphragm to form an upper pressurized gas portion and a lower pressurized fluid portion, and an indicator positioned at an upper part of the expansion tank in communication with the contents of the upper pressurized gas portion. The indicator is configured so as to display a first color if the operating conditions arc normal in the pressurized gas portion, and a second color if the amount of moisture detected in the pressurized gas portion greater than or equal to a predetermined amount. Further disclosed is a method for detecting whether there is an excessive amount of moisture in a pressurized gas portion of an expansion tank by allowing pressurized gas from the pressurized gas portion to come into contact with the indicator, and viewing the color displayed by the indicator. As such, the tank can be simply visually inspected to determine whether there is a potential failure in the tank.

    Abstract: A monitoring system for a multiple-walled fluid system with a first walled region including a flowing or stagnant fluid and at least one second walled region at least partially surrounding the first walled region. The first walled region and the at least one second walled region forming the multiple-walled fluid system, the first walled region being in fluid communication with the at least one second walled region, the at least one second walled region also being in fluid communication with the ambient environment. A data processing device for monitoring at least one pressure difference between a pressure in at least one a control volume and at least one second pressure in the at least one second walled region, a first control volume in fluid connection with the first walled region and the ambient environment. The at least one pressure difference indicating the status of the multiple-walled fluid system.
