Abstract:
The invention relates to a system for sealing a pipeline system, comprising a fluid-tight hose (1) for inserting into the area of the gap (2) between two pipes (3a, 3b) of a pipeline system to be sealed. The hose (1) is provided with a supply element (4) containing a valve (4a) for introducing the fluid into the hose (2), and the system is provided with a pump for conveying the fluid, wherein said pump can be connected to the supply element (4). In particular, the hose (2) contains material that can be vulcanized or welded, and the hose can be connected to a ring by vulcanization or welding. A very safe and easy-to-handle system for sealing a pipeline system is thereby created.
