Abstract
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.
Claims1
A pipe coupling assembly for providing fluid communication between the interstices of pipes engaged to opposite ends of a pipe fitting and to a connector tube bypass assembly, comprising:
- a pipe fitting having at least two opposite ends;
- a first pipe engaged to one end of the pipe fitting;
- a second pipe engaged to an opposite end of the pipe fitting;
- wherein each of the first and second pipes comprises an inner tubular member, an outer tubular member and an interstice therebetween;
- a first pipe engaging member for attaching to the first pipe;
- a second pipe engaging member for attaching to the second pipe,
- a connector tube bypass assembly for engaging to the first and second pipe engaging members;
- wherein each pipe engaging member comprises;
- a groove;
- and
- a connecting member for receiving the connector tube bypass assembly;
- and
- wherein the groove of the pipe engaging member is in fluid communication with the interstice of the pipe and the connecting member means for receiving the connector tube bypass assembly,
- such that when fluid passes through the first pipe via its interstice, the fluid passes through the groove of the first pipe engaging member to the bypass connector tube to the groove of the second pipe engaging member and to the second pipe via its interstice and not through the pipe fitting.
