PCT-Proppant crush tester

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


The PCT apparatus conducts proppant crush-resistance experiments. The amount of proppant crushed at a specific closure stress is determined in accordance to the test practices of the ISO 13503-2 standard. The device is capable of generating pressures up to 20,000 psi when used with a 50 mm (2 in) diameter piston. Piston displacement is achieved at a controlled, constant rate up to 2,000 psi per minute. The system mainly comprises a servo-controlled load frame and a cylindrical proppant cell. Applied load is constantly monitored and fed back into the controller to adjust crosshead motion and maintain the desired loading rate.
