A pipe joint includes a first pipe that includes a first flange and a second pipe that includes a second flange. A first sleeve is installed within the first pipe and a second sleeve is installed within the second pipe. Further, an annular ring is positioned between the flange of the first pipe and the flange of the second pipe. The annular ring includes a first hub that extends into the first pipe and a second hub that extends into the second pipe. Moreover, a first complementary engagement structure is formed between the first sleeve and the first hub of the annular ring. The first complementary engagement structure provides a first seal interface within the pipe joint. A second complementary engagement structure is formed between the second sleeve and the second hub of the annular ring. The second complementary engagement structure provides a second seal interface within the pipe joint.
