PCT-Proppant crush tester

ISO 13503-2 - API RP 56 / 58 /60


The PCT apparatus is designed to execute proppant crush-resistance tests, adhering to the ISO 13503-2 standard methodologies for determining the extent of proppant crushing under specific closure stresses. Equipped with a 50 mm (2 in) diameter piston, the device can generate pressures reaching up to 20,000 psi. The apparatus operates at a controlled piston displacement rate, capable of attaining speeds up to 2,000 psi per minute. The primary components of the system include a servo-controlled load frame and a cylindrical proppant cell. Continuous monitoring of the applied load is conducted, and this data is fed back into the controller. This real-time feedback adjusts the crosshead motion to sustain the targeted loading rate.
