Patent CA-2267037-A1 (CA)
Inventor: STIGSON JOAKIM
IPC: F16L47/04
Filed: 1999-03-26
Abstract: A clamping ring coupling for connecting a pipe (2) of the type crosslinked polyethylene pipe (PEX pipe) with a conventional pipe element (4) provided with an external thread (6) comprises a coupling nut (8) screwable onto said thread of the pipe element and provided with an internal thread (14) and a clamping ring (10) positioned between the outer surface of the end portion of the pipe (2) and an inner surface of the coupling nut (8) axially inside the internal thread (14) of the coupling nut. The coupling nut and the clamping ring have engagement surfaces contacting each other at the front edge portion of the clamping ring in the direction of screwing the coupling nut onto the pipe element, the engagement surfaces cooperating for forcing the clamping ring (10) against the outer surface of the end portion (2) of the pipe when the coupling nut (8) is tightened onto the pipe element (4). The internal thread (14) of the coupling nut (8) is flattened at its thread tops (at 30) for providing an internal diameter of the coupling nut (8), which exceeds the normal tolerance of the thread in order to make it possible to provide the clamping ring coupling with a clamping ring (10) of such an outer diameter that the clamping ring can be formed with sufficient material thickness so as to be used for fixing a crosslinked polyethylene pipe (2) in the clamping ring coupling.
