Abstract: Disclosed is a method and apparatus for use in a fusion process for conduit. The method includes: heating and melting at least a portion of the terminal edges of the first conduit portion and the second conduit portion; and butt fusing the melted terminal edge of the first conduit portion with the melted terminal edge of the second conduit portion, thereby creating a fused joint area. A fusion apparatus for employing this method is also disclosed.

Abstract: Disclosed is a system and method for conduit expansion for use in expanding a liner conduit within a host conduit. The system includes injection hardware positioned on a first end of the liner conduit and the host conduit, and distal end cap hardware positioned on a second end of the host conduit and liner conduit. Both the injection hardware and the distal end cap hardware are in communication with a control mechanism for use in monitoring and/or controlling the operating parameters of the system.
