A joint ring system for lined pipes includes a first pipe and a second pipe joined end-to-end, each pipe having an interior lining covering substantially all of an interior wall of the respective pipe. A first ring is disposed within and substantially flush with the joined end of the first pipe, and a second ring is disposed within and substantially flush with the joined end of the second pipe. The first ring is configured to create a first circumferential pressure seal against the interior wall of the first pipe, and the second ring is configured to create a second circumferential pressure seal against the interior wall of the second pipe. At least one of the first ring and the second ring is configured to create a pipe joint pressure seal against the other ring.
