Coal Core Permeability Tester

Coal Core Permeability Tester

Under pseudo-triaxial stress, temperature, and other multi-field coupling experimental conditions, physical simulation experiments on the seepage of coalbed methane in the medium are conducted. Through temperature, axial/confining pressure, and other testing systems, the seepage characteristics of coalbed methane in coal under multi-physical conditions are studied; (1) Apply axial/circumferential stress with a magnitude of 20 MPa; (2) Use electric heating to control the temperature field during the process, achieving temperatures up to 120°C under fully sealed conditions; (3) Capable of testing gas seepage characteristics of core samples under pseudo-triaxial pressure conditions; (4) Suitable for permeability studies of different test gases.
