Techniques for implementing a pipeline system that includes a segment and a pipe fitting. The pipe segment includes an inner barrier layer, a first intermediate layer in an inner tubing annulus, an intermediate barrier layer disposed around the inner tubing annulus, a second intermediate layer in an outer tubing annulus, and an outer barrier layer disposed around the outer tubing annulus. The pipe fitting includes a fitting body that defines a fitting bore, a fitting jacket secured to the fitting body to define a tubing cavity, in which the fitting jacket is conformally deformed around the outer barrier layer of the pipe segment, and an annulus divider ring secured to the fitting jacket to divide the tubing cavity into an outer fitting annulus and an inner fitting annulus, in which the annulus divider ring is conformally deformed around the intermediate barrier layer of the pipe segment.

The test head includes a shell, which defines an annulus cavity, and an inflatable bladder implemented in the annulus cavity, in which the system maintains the inflatable securing bladder in a less inflated state while pipe segment tubing is not present in the annulus cavity and increases inflation of the inflatable bladder to a more inflated state when the tubing is present in the annulus cavity to facilitate securing and sealing an open end of the pipe segment in the test head to enable integrity of the tubing to be tested at least in part by flowing a test fluid into the annulus of the tubing via a testing port on the shell.
