<p>A clamping and reinforcing ring for a pipe wrapped with high strength metal strapping. The clamping and reinforcing ring comprises a unitary metal annulus which is fitted over the wrapped pipe, and having a concave inner surface in the central portion of the annulus. When the wrapped pipe is expanded in the radial direction, the concave portion of the annulus is deformed to increase the radius of curvature and thereby produce a spring force pressing radially inwardly on the wrapped pipe. One or both peripheral portions of the annulus are bent outwardly away from the surface of the wrapped pipe to facilitate fitting of the ring over the wrapped pipe.</p> |
