Wille - Model HP HT - High-Pressure High-Temperature Triaxial Rock Testing System
These advanced rock testing plants enable our customers to meet all test requirements in rock research testing. The modular systems can be configured with various types of hydraulic actuators with different load ranges, a variety of test jigs, triaxial cells with different specimen diameter and pressure ranges, pressure controllers as well as different sensors with the necessary attachments.
Advanced software packages and further accessories can also be arranged to suit your specific testing needs.
The systems are able to test a range of materials from soft rock (e.g. sandstone) to hard rock and building materials with high-strength.
A variety of jigs and attachments to perform uniaxial compressive strength, triaxial strength, post failure, bending, indirect tensile, direct tensile, fracture toughness, creep, flexural and cyclic loading tests are available.
- Fitted frame sizes and load ranges from 500 to 5,000 kN with different actuators for each test requirement
