Non-Destructive Testing (NDT)
Non destructive testing is a descriptive term used for the examination of a material or component in such a way that allows it to be examined without changing or destroying its usefulness.
NDT plays a fundamental role in everyday life and is necessary to assure safety and reliability of equipment such as lifts, hoists, moving footways, conveyors and transporters. Typical examples of such equipment are found in aircraft, motor vehicles, pipelines, bridges, trains, power stations, refineries and oil platforms, to name a few, which are all inspected using NDT.
NDT is a Quality Assurance management tool which can give impressive results when used correctly. It requires an understanding of the various methods available, their capabilities and limitations, knowledge of the relevant standards and specifications for performing the tests.
Materials, products and equipment which fail to achieve their design requirements or projected life due to undetected defects may require expensive repair or early replacement. Such defects may also be the cause of unsafe conditions or catastrophic failure, as well as loss of revenue due to unplanned plant shutdown.
Non destructive testing can be applied to each stage of an item's construction. The materials and welds can be examined using NDT and either accepted, rejected or repaired. NDT techniques can then be used to monitor the integrity of the item or structure throughout it's design life.
TestSafe Australia conducts NDT on wire ropes. This can be conducted for most wire ropes up to 70mm diameter as long as there is access to the wire rope and a clear path on the wire rope for the test equipment to operate on.
Normally, the wire rope is driven through the sensing equipment which is stationary, but other techniques can be used for stationary wire ropes.
During testing, loss of Metallic Area (LMA) is measured as well as anomalies in the wire rope. Internal corrosion can also be identified during testing.
TestSafe Australia is NATA accredited for the following NDT:
- 6.62.01 Magnetic flux leakage testing by instrumental indication.
We will also consider undertaking test requirements to other standards or similar tests as required. Should you require any further information, please use our enquiry form.
