Zusammenfassung:	A joining sleeve configured to connect internal liners of two internally lined pipe sections across a welded pipe section joint and a method of use is disclosed. The joining sleeve comprises a sleeve body having a first end and a second end, the first and second ends configured to couple with opposing ends of first and second internal liners respectively. A collar is disposed around the outer surface of the sleeve body, the collar having a first retracted condition in which it has a first outer diameter, and a second expanded condition in which it has a second outer diameter, larger than the first outer diameter.
