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: An effective, easily installed coupling structure for use in securing a pipe in an opening in a member from one side of the member can be constructed so as to utilize an expandable sleeve. Such a sleeve is initially of a cylindrical configuration and is located around a threaded end of the pipe adjacent to a tapered shoulder on the pipe. The pipe is inserted through such an opening so that the sleeve extends through the opening and so that a flange on the sleeve abuts against the member. A nut is then located around the threaded end and relative rotation is caused between the nut and the pipe through the use of a holding structure on the pipe and the nut. Such action holds the sleeve as the pipe is drawn toward the member. Engagement between the sleeve and the shoulder then expands the sleeve so that the pipe is held as the result of the flange engaging one side of the member and the sleeve engaging the other side of the member.

Abstract: A sleeve member for positioning between the fastener and work pieces within aligned holes through the work pieces.
