Abstract
A compression collar is used for reinforcing an interference fit between a piping end and a fitting. The compression collar comprises a reinforcing ring having a tubular geometry with a radially-inward facing surface and a radially-outward facing surface. A sleeve is received around, at least in part, a portion of the radially-outward facing surface of the reinforcing ring and this sleeve wraps around one axial end of the reinforcing ring to form a stop edge thereon.
Claims6
A compression collar for reinforcing an interference fit between a piping end and a fitting, the compression collar comprising:
- a reinforcing ring having a tubular geometry with a radially-inward facing surface and a radially-outward facing surface, the reinforcing ring configured to remain in place about the piping end after expansion of the compression collar due to expansion of the piping end;
- and a sleeve received around, at least in part, a portion of the radially-outward facing surface of the reinforcing ring and wrapping around one axial end of the reinforcing ring and extending radially inwardly beyond the radially-inward facing surface of the reinforcing ring to form a stop edge thereon, the sleeve including a perforation such that the sleeve is configured to tear upon expansion of the compression collar due to expansion of the piping end.
