Reinforced press base, strengthening ring, and method of reinforcing a press base

A high-pressure, high-temperature (HPHT) press comprising:

• six press bases, each press base including:
• a first end having an outer circumference and a top surface,
• a second end,
• a piston cavity located adjacent the second end, the piston cavity housing a piston,
• wherein the six press bases are arranged such that each piston is displaceable toward a common region, and wherein at least one press base of the six press bases comprises:
• at least one strengthening ring positioned around, and configured to fixedly contact with, an outer circumference of the first end of the at least one press base, the at least one strengthening ring including:
• an upper surface generally facing the same direction as the top surface, a distance between the top surface and the second end is greater than a distance between the upper surface and the second end, and the upper surface is spaced below the top surface;
• a bottom surface opposite the upper surface;
• and
• an inner diameter wall of the at least one strengthening ring is configured to contact with only the outer circumference of the first end, the inner diameter wall extending between the upper surface and the bottom surface, wherein the top and bottom surfaces are positioned adjacent to the first end of the press base.
