Abstract
A flexible pipe joint coupling apparatus for attaching a pipe to a flange comprises a pipe portion which fits into an alignment ring which is attached in turn to the flange. The alignment ring provides centering and anchoring of the pipe portion. A yieldable gasket is positioned between the end of the pipe portion and the flange. Spaced from the end inserted into the alignment ring is an attachment system which basically includes a flange formed in the outer wall of the pipe portion. A restraining ring is slipped over the outer diameter of the pipe portion and engages the flange. Holes are spaced around the alignment ring, the flange and the restraining ring in a manner to place bolts through the holes in order to attach the pipe portion to the flange.
