Sealing and drainage device for pipe; has leakage point and has cuff of flexible material with opening and closing device and inflatable binding that presses cuff to seal pipe when inflated

摘要

The device has a leakage point, preferably in the area of a flange connection (22). A cuff of flexible material has axial end areas (26), an opening and closing device, for pressure and fluid-tight sealing and a drain. An inflatable binding (42) arranged outside each axial end area presses against the end areas to seal the pipe (20), when inflated. Preferably, the opening and closing device runs axially along the edges of the cuff.
