Gas Hydrate CT Stress-Path Triaxial System
Miniature Triaxial CT System for Gas Hydrates
Technical Specifications: Natural Gas Hydrate CT Triaxial Testing System
The system must integrate conventional triaxial testing capabilities for both geotechnical materials and natural gas hydrate (NGH)-bearing sediments, supporting in-situ NGH formation/decomposition with independent stress-field and temperature-field control. During mechanical testing, the inspeXio SMX-225CT (max resolution: 0.015mm) scans NGH specimens (grain size ≤100μm) to analyze micro-scale deformation (e.g., shear bands, porosity evolution). Pressure chamber design must balance X-ray transmissivity and safety (factor ≥2).
