ABSTRACT:
A process to install an interlocking union for joining a first double containment pipe having a first carrier pipe within a first containment pipe to a second double containment pipe having a second carrier pipe within a second containment pipe. The process includes slipping a first locking ring into position over the outside diameter of the first carrier pipe to stop against the first containment pipe. A carrier coupling is adhesively bonded to the first carrier pipe stopping against the first locking ring. Thereafter, a second locking ring is slipped into position over the second carrier pipe stopping against the second containment pipe. The carrier coupling is adhesively bonded to the second carrier pipe stopping against the second locking ring. Finally, a containment coupling is bonded to the first containment pipe and to the second containment pipe.
