Non-Destructive Testing (NDT)
Inspection and examination of materials, components and assemblies are required in order to determine if they comply with design specifications, standards or are defective.
Of utmost concern for newly manufactured or 
constructed items is their ability to withstand the mechanical stresses or chemical attack to which they are expected to be exposed to.
For items that are already in service, the question is whether or not the item will continue to function satisfactorily in its service environment until the next scheduled inspection.
The essential feature of Non-Destructive Testing (NDT) is that the process itself produces no deleterious effects on the material or structure under examination.
Specialists in positive material identification (PMI), alloy verification (AV), ultrasonic testing, dye and fluorescent penetrant inspection. magnetic particle testing, eddy current testing, visual inspection, thickness measurement, corrosion mapping, video endoscope examination and thermal imaging.
Heat exchanger testing and pasteuriser inspection
Independent Integrity Inspection Limited (INDEi) offers innovative solutions for the crack testing and inspection of various type heat exchangers and pasteurisers including plate, tubular and scraped type heat exchangers.
Using our unique bespoke testing methods, we are able to quickly inspect, report and provide assistance for all your inspection requirements to meet HACCP and CCP requirements
Our services are proven to provide a crucial edge in a preventative maintenance program; by the definitive testing of heat exchangers and pasteurisers. Our rapid, accurate testing methods allow several heat exchangers to be tested in a single day which reduces production downtime and eliminates potential cross-contamination issues being created within the production process line.
Independent Integrity Inspection Limited utilises both the saline conductivity method and the helium gas methods, we provide both services to give you the option to choose your preferred method of integrity testing that's most suitable to your heat exchangers and production requirements.
