Non-destructive testing (NDT) and examination (NDE)

The LoneStar Group is strengthened by in-house independent ISO 17025-accredited test laboratories strategically placed across key global marketplaces. Within these state-of-the-art facilities, we evaluate mission-critical materials, products and components for customers who seek the highest possible national and international standards, including ISO/DIN/ASTM/ASME/JIS/BS specifications.

Applied to non-magnetic materials and uses the capillary action of a coloured dye with a developer to highlight any defects within the material. 

A solution with fluorescent magnetic particles is released around magnetised parts. Particles concentrate around defects, as seen by ultra-violet light.

UT enables accurate internal inspection without cutting, breaking or damaging raw materials. This method uses high-frequency sound waves from 0.5-10 MHz to detect defects such as inclusions, cracks or voids.

PMI is used to verify if the chemical composition of a material conforms and matches the specified grades. Most PMI is carried out using x-ray fluorescence (XRF) that uses x-rays to excite atoms in the material and measures emitted fluorescent energy resulting in the identification of Cr, Ni Mo, Cu Ti and Nb elements.
