ABSTRACT:
Methods and apparatus are described for improved sealing across an annular space between facing sealing surfaces. Methods for mechanically setting and pressure energizing sealing ring assemblies are also described. In one aspect, several sealing ring assemblies are described, each of which include an outer seal body formed of elastically deformable metal and having an annular base with a pair of legs extending from the base to form a channel. A plurality of predominately non-deformable segments are positioned between the legs. The use of segments substantially reduces detrimental hoop stress which would hinder effective setting of a seal between the inner and outer members. In preferred embodiments, the legs and the segments each present raised portions which are offset from each other. The offset arrangement of the raised portions permit the ring assembly to be mechanically set by radial spring loading through elastic deformation of portions of the seal body. The ring assembly is then further energized through increased fluid pressure within the annular space which enters the channel of the seal ring to urge the legs into tighter engagement with the inner and outer members.
