초록

A pipe joint and can include a first pipe having a flange and a second pipe having a flange. A first sleeve can be installed within the first pipe and a second sleeve can be installed within the second pipe. Moreover, an annular ring can be disposed between the flange of the first pipe and the flange of the second pipe. The annular ring is configured to engage the first sleeve and the second sleeve and create a sealing engagement between the annular ring, the first sleeve and the second sleeve when a compressive force is applied to the first sleeve, the ...
