  • System for sealing a pipeline system
    Patent number: 9145998
    Abstract: A system is provided that includes a fluid-tight tube, which for insertion can be introduced into the area of a gap to be sealed between two pipes of the pipeline system to be sealed. The tube is provided with a feed element for introducing a fluid, with whose aid the tube is filled and thereby increased in its volume. The feed element contains a valve, which facilitates the introduction of the fluid and at the same time prevents the outward flow via the feed element.
