Non-Destructive Testing

Non-Destructive Testing (NDT) is a wide group of analysis techniques used in industry to evaluate the properties of materials, components or systems without causing damage. The terms Non-Destructive Examination (NDE), Non-Destructive Inspection (NDI), and Non-Destructive evaluation (NDE) are also commonly used to describe this technology. Because NDT does not permanently alter the article being inspected, it is a highly valuable technique that can save both money and time in product evaluation, troubleshooting, and research.

Note: Inspectors travel from Mississauga to all over Canada.

Equipment Reliability

GTT OnSET through its experienced technical personnel have developed reliability programs for industrial equipment including boilers, pressure vessels, HVAC equipment, storage tanks and related components.

We use engineering and industry standards along with various non-destructive testing techniques to evaluate the present condition of equipment and determine what needs to be completed to bring the equipment into an efficient operating condition. This can include both repairs/upgrades to the equipment and/or changes to operating procedures.

The GTT OnSET team also performs complete system evaluations related to heating and cooling.

Our reliability programs were developed to save our clients money by:
• Assuring that all equipment vital to capital investment programs are reliable
• Avoiding expensive emergency breakdown and repair costs
• Improving equipment and system reliability
• Increase the life of the equipment and improve system efficiency with recommendations derived from the evaluation
