High Pressure High Temperature Triaxial cell

This is an advanced high-pressure triaxial cell designed to test rock samples with diameters of up to 102 mm, a length/diameter ratio of at least 2 under triaxial high pressure/temperature conditions. The axial load can reach up to 5,000 kN.
The cells are designed for testing the shear and creep characteristics of rock core samples or solid materials (e.g. Granites, evaporates, cemented tills or Clays) under triaxial stress conditions.
This series of triaxial cells fits inside various types of load frame that we produce. To apply confining pressure, we offer different types of high pressure pump as well as pressure intensifiers in different pressure ranges. Axial and radial strains are measured by internal axial and radial deformation measuring devices, which work in high pressure and high temperature conditions. These give precise measurements of deformation modules and Poisson’s ratio.
