In a poorly understood, nonlinear way, tungsten carbide core
life is inversely proportional to pressure. Core lifetime is
long (>100 runs), for experiments conducted at 10 to 15 kbar,
but short (<100 runs), at 40 kbar. In any vigorous research
laboratory, where experiments are conducted at the limits of
current knowledge, pressure plate cores will crack and fail to
hold pressure.
Depths of the Earth Company offers repair service to replace
damaged cores with new cores. To utilize the repair service,
disassemble the pressure plate from the cooling jacket assembly.
Send the pressure plate AND piston to Depths of the Earth Company,
along with a purchase order from your company or academic institution.
Repair time is 4 to 10 weeks, depending on tungsten carbide availability.
It is very important that the piston be sent with the plate.
Following press-in of the new core, the core ID is precision
honed to fit the piston with 0.0005” clearance. A smaller
clearance can cause the core to fail, while a larger clearance
will not hold pressure.
