Multi-annuli pipe fitting systems and methods

A pipe fitting configured to be secured to a pipe segment, comprising:

• a fitting body that defines a fitting bore that is configured to be fluidly connected to a pipe bore defined by an inner barrier layer of the pipe segment;
• a fitting jacket secured to the fitting body to define a tubing cavity, wherein the fitting jacket is configured to be conformally deformed around an outer barrier layer of the pipe segment to facilitate securing the pipe fitting to the pipe segment;
• an annulus divider ring that divides the tubing cavity into:
• an outer fitting annulus that is configured to be fluidly connected to an outer tubing annulus defined between the outer barrier layer and an intermediate barrier layer of the pipe segment;
• and
• an inner fitting annulus that is configured to be fluidly connected to an inner tubing annulus defined between the intermediate barrier layer and the inner barrier layer of the pipe segment, wherein the annulus divider ring is configured to be conformally deformed around the intermediate barrier layer of the pipe segment to facilitate blocking fluid flow directly between the inner fitting annulus and the outer fitting annulus;
• and
• a vent port fluidly connected to the inner fitting annulus to facilitate venting the inner tubing annulus of the pipe segment.

A midline pipe fitting configured to be secured between a first pipe segment and a second pipe segment, comprising:

• a fitting body that defines a fitting bore that is configured to fluidly connect a first pipe bore defined by a first inner barrier layer of the first pipe segment and a second pipe bore defined by a second inner barrier layer of the second pipe segment;
• a first fitting jacket secured to the fitting body to define a first tubing cavity, wherein the first fitting jacket is configured to be conformally deformed around a first outer barrier layer of the first pipe segment to facilitate securing the midline pipe fitting to the first pipe segment;
• a first annulus divider ring that divides the first tubing cavity into:
• a first outer fitting annulus that is configured to be fluidly connected to a first outer tubing annulus defined between the first outer barrier layer and a first intermediate barrier layer of the first pipe segment;
• and
• a first inner fitting annulus that is configured to be fluidly connected to a first inner tubing annulus defined between the first intermediate barrier layer and the first inner barrier layer of the first pipe segment, wherein the first annulus divider ring is configured to be conformally deformed around the first intermediate barrier layer of the first pipe segment to facilitate blocking fluid flow directly between the first inner fitting annulus and the first outer fitting annulus;
• a second fitting jacket secured to the fitting body to define a second tubing cavity, wherein the second fitting jacket is configured to be conformally deformed around a second outer barrier layer of the second pipe segment to facilitate securing the midline pipe fitting to the second pipe segment;
• and
• a second annulus divider ring that divides the second tubing cavity into:
• a second outer fitting annulus that is configured to be fluidly connected to a second outer tubing annulus defined between the second outer barrier layer and a second intermediate barrier layer of the second pipe segment;
• and
• a second inner fitting annulus that is configured to be fluidly connected to a second inner tubing annulus defined between the second intermediate barrier layer and the second inner barrier layer of the second pipe segment, wherein the second annulus divider ring is configured to be conformally deformed around the second intermediate barrier layer of the second pipe segment to facilitate blocking fluid flow directly between the second inner fitting annulus and the second outer fitting annulus.
