Abstract
Techniques implementing and/or operating a system includes a pipe segment and a test head assembly secured to the pipe segment. The pipe segment includes tubing that defines a pipe bore through the pipe segment and a fluid conduit in a tubing annulus of the pipe segment. The test head assembly includes barrier material poly welded to the tubing of the pipe segment to facilitate sealing the fluid conduit defined in the tubing annulus from environmental conditions external to the tubing of the pipe segment and a fluid port fluidly connected to the fluid conduit defined within the tubing annulus 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 via the fluid port, extracting fluid from the fluid conduit defined in the tubing annulus via the fluid port, or both.
