A disassembleable and reassembleable sealing device for pipelines, includes a cylindrical sealing insert being insertable into a pipeline in a given direction, the sealing insert having a front cup part with a closed cross section and a rear ring part, as seen in the given insertion direction, the cup and ring parts being annular, coaxial and slideable into each other in axial direction of the sealing insert, the cup and ring parts having corresponding peripheral surfaces and ring shoulder surfaces at the outer periphery of the cup and ring parts defining at least one ring seat, at least one sealing ring inserted into the ring seat between the cup and ring parts, the sealing ring being bulged outward by deformation forces exerted on the sealing ring by the ring seat when the cup and ring parts slide toward each other, increasing the diameter of the sealing ring for pressing the sealing ring against the ring seat and forming a ring bead on the sealing ring resting against the inner periphery of the pipeline forming a seal, and an operating device being coupleable to and uncoupleable from the sealing insert for transporting, inserting and disassembling the sealing insert.

A disassembleable and reassembleable sealing device for pipelines, comprising a cylindrical sealing insert being insertable into a pipeline in a given direction, said sealing insert having a front cup part with a closed cross section and a rear ring part, as seen in said given insertion direction, said cup and ring parts being annular, coaxial and slideable into each other in axial direction of said sealing insert, said cup and ring parts having corresponding peripheral surfaces and ring shoulder surfaces at the outer periphery of said cup and ring parts defining at least one ring seat, a series of solid sealing rings inserted into said at least one ring seat between said cup and ring parts, means for sliding said cup and ring parts toward each other mechanically bulging said sealing rings outward by deformation forces exerted on said sealing rings by said at least one ring seat, increasing the diameter of said sealing rings by pressing said sealing rings against said at least one ring seat and forming a ring bead on said sealing rings resting against the inner periphery of the pipeline forming a seal, and an operating device being coupleable to and uncoupleable from said sealing insert for transporting, inserting and disassembling said sealing insert and for actuating said sliding means, said cup part being in the form of a tightening element moveable in both axial directions relative to said ring part for tightening said sealing ring, said cup part including a turnbuckle extending through said cup and ring parts and having a thread, a lock nut disposed on said thread of said turnbuckle for locking said cup part relative to said ring part in a tightened position, means for turning said lock nut by remote control, said operating device including a tightening tool with a tightening cylinder associated with said ring part and a tightening piston disposed in said tightening cylinder and associated with said turnbuckle, and means for feeding pressure medium to said tightening cylinder causing said tightening piston to move said turnbuckle and tighten and loosen said cup part relative to said ring part by remote control.
