A pipe coupling assembly for double-wall pipe having an interstice between an inner pipe and an outer pipe, which joins the terminal ends of adjacent sections of the double-wall pipe to a fitting element, as a tee or elbow fitting, as well as to a connector tube bypass assembly. The coupling assembly provides fluid communication between the interstices of the adjacent sections of the double-wall pipe and the connector tube bypass assembly but does not permit fluid from the interstices of the pipes to pass through the pipe fitting.
