A dual seal accommodates radial and axial movement, and accommodates positive and negative pressure differentials, when in sealing engagement about a rotating shaft.
The present invention provides a packing yarn that utilizes a non-metal woven reinforcement that provides lateral as well as longitudinal strength while improving the wear characteristics of the yarn material. To increase the support provided by the woven reinforcement, the yarn material and woven reinforcement are folded together such that the woven reinforcement is substantially coextensive with the yarn material in the resulting packing yarn.
Subsea wells have a variety of proprietary well head configurations that require sophisticated locking and sealing profiles that allow the well bore to be sealed off and the production of hydrocarbons to be safely controlled. A universal tubing hanger and lockdown assembly uses a sealing apparatus to annularly seal the well bore. When compressed, a multi-piece stacked sealing system employs rigid and elastic members to seal the well bore annulus in both the top-down and bottom-up directions. Top-down pressure containment is needed for appropriate well system testing and bottom-up pressure containment is necessary to control the internal pressure of the well.

A split mechanical composite seal assembly (10) for providing a seal between a rotating shaft (12) and a static surface (14). The split mechanical composite seal assembly includes first and second axially adjacent annular seal elements (20, 30). The first and second seal elements each include a sealing edge contacting the shaft to provide a respective seal between the first and second seal element and the shaft. A static housing (40) receives the first and second seal elements and engages the static surface to provide a static stationary seal, while concomitantly providing a flex region that engages the seal elements to form a dynamic seal therewith. A holder assembly (110) receives one seal element and may include a double-angled lead-in to facilitate installation of the seal element. The holder assembly may include a detent groove (189) for receiving and retaining an O-ring (188) disposed about the seal element. The static housing may comprise two mating segments having overlapping surfaces.
