摘要： A sealing element for a rotating control device includes an elastomeric body having a central bore for sealing against a pipe passing therethrough. The elastomeric body has an upper portion which is internally reinforced with a frame and a lower portion formed with a plurality of protrusions. The radial protrusions provide columnar support to the lower portion permitting the lower portion to resist centrifugal and frictional forces against the lower portion during drilling and other operations. The sealing element may be used to form an assembly with reusable parts for connecting the sealing element to a mandrel of a rotating control device.

摘要： A method for manufacturing a sealing device to improve the positioning accuracy of a parting operation while also improving manufacturing efficiency. The method includes molding an elastomeric cylindrical molded body (100a) with a plurality of cylindrical surface portions (130) and a plurality of annular outer peripheral convex portions (110) arranged alternately on an outer peripheral side thereof, and further provided with a plurality of cylindrical surface portions and a plurality of annular inner peripheral convex portions arranged alternately on an inner peripheral side thereof. The cylindrical surface portions on the outer peripheral side and the cylindrical surface portions on the inner peripheral side, as well as the outer peripheral convex portions and the inner peripheral convex portions are provided so as to be at the same positions in the axial direction.

摘要： A radial shaft seal includes a powder coating on a shaft and a sealing lip that lands on the powder coating. The powder coating is formed of a thermosetting resin and a filler material. The filler material has a melting point above the cure temperature of the thermosetting resin. The powder coating may be porous. The powder coating may be made up of dry powder particles adhered to one-another with spaces in between. The filler may be present in an amount between 15% and 35% within the individual particles. The powder coating is adapted to wear away at locations of maximum interference with the sealing lip while continuing to provide a durable seal. This wear behavior compensates for shaft wobble.

摘要： An annular seal including a body defining a central lumen and a weakened portion disposed around the central lumen. In an embodiment, the weakened portion includes at least one aperture or a plurality of apertures. In a further embodiment, the apertures may be identical to one another. An annular seal including a body defining a central lumen bounded by a sidewall, wherein the body has a dual-elastic modulus profile including a first elastic modulus, S1, as measured along the sidewall prior to assembly with an inner component, and a second elastic modulus, S2, as measured along the sidewall after assembly with the inner component, and wherein the first elastic modulus is less than the second elastic modulus.
