A pipe joint is disclosed and can include a first pipe (1602) comprising a first flange (1612) and a second pipe (1604) comprising a second flange (1622). A first sleeve (1630) can be installed within the first pipe (1602) and a second sleeve (1640) can be installed within the second pipe (1604). Moreover, an annular ring (1650) can be positioned between the flange (1612) of the first pipe (1602) and the flange (1622) of the second pipe (1604). The annular ring (1650) can comprise a first hub (1652) that extends into the first pipe (1602) and a second hub (1654) that extends into the second pipe (1604). A first complementary engagement structure can be formed between the first sleeve (1630) and the first hub (1652) of the annular ring (1650), and a second complementary engagement structure can be formed between the second sleeve (1640) and the second hub (1654) of the annular ring (1650). The first complementary engagement structure can provide a first seal interface within the pipe joint, and the second complementary engagement structure can provide a second seal interface within the pipe joint.
