Abstract
A press base may include a piston cavity formed in the press base and a piston cavity sleeve positioned in the piston cavity. The piston cavity sleeve may include a wall having an outer surface and an inner surface opposite the outer surface. The piston cavity sleeve may further include a floor having an upper surface and a lower surface opposite the upper surface. An outer radius may be formed at a juncture of the outer surface of the wall and lower surface of the floor and an inner radius may be formed at a juncture of the inner surface of the wall and upper surface of the floor. The inner radius may exhibit a radius of curvature that is greater than a radius of curvature of the outer radius.

A piston cavity sleeve for a high-pressure, high-temperature (HPHT) press base comprising:
- a wall having an outer surface and an inner surface opposite the outer surface;
- a floor having a flat upper surface and a lower surface opposite the flat upper surface;
- an outer radius transitioning from the outer surface of the wall to the lower surface of the floor;
- and
- an inner radius transitioning from the inner surface of the wall to the flat upper surface of the floor, wherein the inner radius exhibits a radius of curvature that is greater than a radius of curvature of the outer radius.
A piston cavity sleeve for a high-pressure, high-temperature (HPHT) press base comprising:
- a cylindrical outer surface;
- a wall including the cylindrical outer surface and an inner surface opposite the cylindrical outer surface, wherein the wall exhibits a thickness between approximately 0.5 inch and approximately 2.0 inches from the inner surface to the outer surface;
- a floor having an upper surface and a lower surface opposite the upper surface, the floor exhibiting a substantially circular geometry, wherein the floor exhibits a thickness between approximately 0.5 inch and approximately 2.0 inches from the upper surface to the lower surface;
- an outer radius transitioning from the cylindrical outer surface of the wall to the lower surface of the floor;
- and
- an inner radius transitioning from the inner surface of the wall to the upper surface of the floor, wherein the inner radius exhibits a radius of curvature that is greater than a radius of curvature of the outer radius, wherein the inner radius exhibits a radius of curvature of at least approximately 5 inches.
