Patent ID: 6899356

Claim:
A subterranean well tubular connection floating shoulder ring for installation in a tubular connection of a pair of pins between the pin ends, the shoulder ring comprising: a body having a central opening therethrough, a first end face on the body, an opposite end face on the body, an inner surface adjacent the central opening and extending between the first end face and the opposite end face and an outer surface extending between the first end face and the opposite end face, the body having about its circumference a substantially uniform cross sectional shape between the first end face, the opposite end face, the inner surface and the outer surface and the ring shaped such that its radius to the outer surface varies around the outer surface circumference to form a plurality of lobes prior to installation, the plurality of lobes defining an outer lobe radius for the ring, such outer lobe radius being reduced by radial forces developed upon installation of the ring in the tubular connection.
