Non Destructive Testing (NDT) Services
Certified inspection that finds defects early, verifies weld quality and supports integrity decisions without taking assets apart.
Overview
See inside your assets without damaging them
Non destructive testing lets operators confirm the condition of welds, pipes, pressure vessels, tanks and structures while they remain in service or during construction. Optimity Global provides qualified NDT technicians and inspection engineers who apply the right method to the right defect, then report results clearly so you can act.
Our services support new construction quality control, in-service inspection programmes, shutdown inspections and failure investigations. We work to approved procedures, use calibrated equipment and deliver reports that integrate with your integrity management and risk-based inspection programmes.
