Abstract
A seal, in certain embodiments, includes a seal body having a groove on a face of the seal body. The face is configured to contact a surface of a separate component to form a seal. The groove interrupts continuity of the face between a first face portion and a second face portion. In addition, the groove enables material deformation laterally between the first face portion and the second face portion. Furthermore, the groove increases contact stress at corners between opposite walls of the groove and the respective first and second face portions.
Claims20
A seal, comprising:
- an annular body having a first material composition comprising a first elastomer, wherein the annular body comprises:
- an inner annular face configured to contact and seal against an inner annular body, wherein the inner annular face includes a first inner semi-circular groove about an inner circumference of the annular body;
- and
- an outer annular face is configured to contact and seal against an outer annular body, wherein the outer annular face includes a first outer semi-circular groove about an outer circumference of the annular body, and the first inner and outer semi-circular grooves are configured to increase contact stress and enable material deformation into the first inner and outer semi-circular grooves.
A system, comprising:
- a first body of a mineral extraction system;
- a second body of the mineral extraction system;
- and
- a seal disposed between the first and second bodies of the mineral extraction system, wherein the seal comprises a seal body having a first face and a second face, the first face is configured to contact the first body and the second face is configured to contact the second body, the first face includes a first semi-circular groove that interrupts continuity of the first face between a first face portion and a second face portion, and first opposite side walls of the first semi-circular groove are perpendicular to the first face.
A seal, comprising:
- a seal body, comprising:
- a first semi-circular groove on a first face of the seal body, wherein the first face is configured to contact a first surface of a first component to form a first seal, and first opposite side walls of the first semi-circular groove are perpendicular to the first face;
- and
- a second semi-circular groove on a second face of the seal body on an opposite side from the first face, wherein the second face is configured to contact a second surface of a second component to form a second seal, and second opposite side walls of the second semi-circular groove are perpendicular to the second face.
