ABSTRACT:
A plastic ring is spun onto the end of a plastic pipe, the heat of friction fusing the contacting surfaces between the ring and the pipe, forming a weld therebetween upon cooling. The ring provides greater radial rigidity at the end of the pipe, and carries a flange extending beyond the outside diameter of the pipe. A flexible sleeve is slipped over the ends of two adjacent sections of such pipe with the flanges in abutting position. Band-type clamps surround the sleeve overlying the rings and are tightened to effect a seal between the sleeve and the periphery of the flanges. The end rings are spun onto the pipe ends with either the inside or the outside diameter of the pipe engaging the interfering surface on the ring in two different embodiments.
