ABSTRACT:
A non-metallic pipe collar is provided which encircles the external surface of a pipe. The pipe collar may be provided in several segments or single collar with a hinged portion which allows the collar to be spread open and placed around a pipe.
In an alternate embodiment shims having a tapered outer surface are placed against the outer surface of the pipe before the pipe collar is placed around the pipe. The pipe collar has a tapered inner surface thus causing an interference fit between the shims and the pipe collar.
