1,000,000 lbf Triaxial Test Apparatus
with Transient Pulse Permeability
RESPEC’s mechanical and hydrologic properties laboratory is one of the best
equipped laboratories in the world for studying rock behavior under complex
coupled thermal, mechanical, and hydrologic loading conditions. Four
computer-controlled servohydraulic testing systems and ten computer-controlled
triaxial compression creep testing systems can apply:
-
Tensile strength
-
Axial loads to 4.5 MN (l,000,000 pounds)
-
Confining and pore pressures to 140 MPa (20,000 psi)
-
Temperatures to 300°C (570°F).
The testing systems can be equipped with liquid or gas permeability systems,
sophisticated electronic instrumentation for on-the-specimen deformation
measurements and ultrasonic velocity/acoustic emission measurements at
temperatures to 175°C (350°F), or a pressure vessel designed especially for
applying multiaxial stress paths.
RESPEC engineers are experienced with formulating testing and analysis programs
for routine quality control testing conducted according to the standard methods
recommended by ASTM, ISRM, or API and for specialized testing conducted to
resolve specific customer problems and regulatory concerns.
The following mechanical and hydrologic testing services are available:
