Non-Destructive Testing (NDT)
Non-destructive testing is used as part of a manufacturing or installation inspection to check if quality demands are being met. As an example, welded steel joints are x-rayed to check the quality of the welding. The radiographic test reveals if the joint is fully welded or contains unacceptable faults.
Non-destructive testing is also used as part of in-service inspections or preventive maintenance to quantify the status of critical components and equipment. As an example, the steel plate floor of a storage tank can be inspected with a special floor scanner. The floor may be subject to corrosion and the scanner measures the remaining plate thickness. If too thin, the plate needs to be replaced to avoid the tank starting to leak.
