Abstract: A system and method of use thereof to produce pipe connections to conduits which have been remediated using a liner. A pipe clamp is attached after a bore has been made and is secured with a clamping strap, for example. A pipe connection adapter with a flange collar and a seal arranged thereon is introduced from the inside of the pipe. An anti-rotation device between the pipe clamp and the pipe connection adapter ensures that the latter assumes a precisely defined position, such that a flange collar, with a shape corresponding to the intersection curve of the conduit/bore, provides a seal on the liner exactly on the edge of the bore. Connection can also be made from the outside of the conduit.

Abstract: To produce pipe connections to conduits (10), such as drinking water main lines which have been remediated using a liner (12), a pipe clamp (20) is attached after a bore (21) has been made, and is secured with a clamping strap (22), for example. A pipe connection adapter (14) with a flange collar (15) and a seal (34) arranged thereon is introduced from the inside of the pipe (10). The anti-rotation device (29) between the pipe clamp (20) and the pipe connection adapter (14) ensures that the latter assumes a precisely defined position, such that its flange collar (15), with a shape corresponding to the intersection curve of the conduit/bore, provides a seal on the liner (12) exactly on the edge (21) of the bore. It is also proposed to insert the connector from the outside of the conduit (10).
