ABSTRACT:
A method of manufacturing an installation-ready pipe coupling is disclosed. The method includes providing pipe coupling segments each having an initial radius of curvature and an initial subtended angle. The segments are each deformed so as to take a permanent set and have a final radius of curvature greater than the initial radius of curvature and a final subtended angle smaller than the initial subtended angle. The deformed segments are assembled in end-to-end relation using adjustably tightenable fasteners to form a coupling. The deformed segments are maintained in spaced relation so that pipe elements can be inserted between them without disassembly of the coupling.
