Abstract
Techniques for implementing and/or operating a system, which includes a pipe segment and a test head assembly. The test head includes an end container, in which an end of tubing of the pipe segment is disposed within the end container, an annulus seal implemented at least in part by solidifying fluid hardening material that is flowed into the end container to facilitate securing the test head assembly to the pipe segment and sealing an opening end of a tubing annulus of the pipe segment within the test head assembly, and a fluid port fluidly connected to a fluid conduit defined within the tubing annulus of the pipe segment to enable integrity of the tubing to be tested at least in part by flowing a test fluid into the fluid conduit defined in the tubing annulus, extracting fluid from the fluid conduit defined in the tubing annulus, or both.
