Excellence
Our Specialized
PAUT & NDT Demonstration Samples
HTHA – High Temperature Hydrogen Attack Test Samples
These HTHA (High Temperature Hydrogen Attack) Test Samples are engineered to help organizations evaluate and validate inspection techniques used to detect hydrogen attack damage in high-temperature environments. Developed with precision machining and realistic defect simulation, these samples replicate microstructural changes caused by hydrogen exposure, including decarburization, blister formation, and micro-cracking. Ideal for advanced NDT applications, they support ultrasonic testing, phased array inspection, and training programs requiring high-fidelity HTHA representations.
IGSCC – Intergranular Stress Corrosion Cracking Demonstration Block
Our IGSCC Demonstration Blocks replicate the complex cracking mechanisms caused by corrosive environments and tensile stress in stainless steel and similar alloys. Manufactured to simulate real-world grain-boundary cracking, these blocks provide accurate defect profiles ideal for NDT training, procedure validation, and equipment performance verification.
These samples help NDT professionals understand sensitivity levels, crack orientation, and response behavior under ultrasonic, eddy current, and phased-array techniques.
HIC – Hydrogen Induced Cracks Test Sample
HIC Test Samples are designed to demonstrate damage caused by hydrogen embrittlement in carbon steel materials. These samples accurately replicate blistering, stepwise cracking, and internal fissures commonly found in petrochemical and refining environments.
They are essential tools for validating UT, PAUT, and corrosion monitoring techniques, ensuring technicians can reliably identify and evaluate hydrogen-induced cracking.
Micro Cracks – Test Sample
Micro Crack Demonstration Blocks are meticulously crafted to represent minute, hard-to-detect cracks typically found in fatigue-stressed materials. These finely engineered samples help NDT professionals master the detection of small surface and subsurface discontinuities.
Designed for precision training and equipment validation, these blocks play a crucial role in qualification programs where high sensitivity and accuracy are required.
