Mid-line connector and method for pipe-in-pipe electrical heating
First Claim
1. A connector of an electrical cable to a pipe-in-pipe pipeline, wherein the pipeline comprises an inner pipe and an outer pipe, said connector comprising:
- a connector housing joinable to the outer pipe of the pipeline;
a blank pipe positioned within said connector housing and joinable to the inner pipe of the pipeline;
at least one pocket mounted in said connector housing, wherein the cable is mateable with the at least one pocket;
a blank pipe conductor electrically coupled between the at least one pocket and the blank pipe; and
an outer pipe conductor electrically coupled between the at least one pocket and the outer pipe.
