Destructive and Non-Destructive Testing Services for Wire Ropes and Lifting Equipment
For over 20 years, non-destructive testing services (NDT) have been a standard requirement for inspecting wire ropes in the mining industry. Using an electronic magnograph machine, NDT inspections fully examine the inside of wire ropes.
Regular non-destructive testing services provide independent verification that a rope can safely remain in service. It also provides an independent condition report to support thorough planning of a replacement time that suits your business demands. At Nobles, we deliver wire rope NDT services for ropes in situ and in service. We also inspect ropes during maintenance periods, when you can conduct cleaning and lubrication simultaneously.
Magnetic Flux Leakage Non-Destructive Testing
NDT wire rope inspections use a magnetic flux leakage device, which passes over the rope to detect corrosion and broken strands of wire. This provides a complete inspection of the rope at the time of testing, which is more thorough than external examinations alone.
Destructive Testing
Destructive testing methods involve inspecting an item on a test bed using tensile force until it reaches its ultimate break load. We then record and provide this to you on a test certificate.
A qualified individual should only perform inspections in a controlled and approved testing laboratory to ensure safety and accurate results.
Our NATA-accredited destructive testing facilities demonstrate our commitment to quality. All testing at Nobles is conducted by qualified individuals in controlled environments. This ensures accurate results and protects the safety of individuals and equipment in compliance with Australian Standards.
Destructive and Non-Destructive Testing FAQs
NDT allows for a full internal and external examination of wire ropes without causing damage. This helps identify hidden wear, corrosion, or broken strands early, enabling businesses to plan replacements proactively rather than waiting for a failure. It ensures ongoing safety, reduces unplanned downtime, and extends the lifespan of critical lifting equipment.
Unlike standard visual inspections, which only assess the outer surface of a wire rope, non-destructive testing (NDT) uses a Magnetic Flux Leakage Device to detect internal defects such as corrosion or broken strands. This provides a more comprehensive assessment, ensuring potential issues are identified before they become critical.
Wire ropes should be tested regularly as part of routine maintenance or whenever there is uncertainty about their condition. Many industries, particularly mining, have adopted NDT as a standard requirement to ensure compliance with safety regulations. Testing can be done while the rope is in use or during scheduled maintenance periods. If inspected during maintenance periods, you can also perform cleaning and lubrication.
Destructive testing is used to determine the ultimate break load of lifting equipment by applying tensile force until failure occurs. This method is valuable for assessing the strength and safety margins of new or sample wire ropes. However, it should only be conducted in controlled, accredited testing facilities. Nobles’ NATA-accredited NDT labs ensure accurate and compliant results for safety-critical applications.
Standard visual inspections only assess the outer surface of wire ropes, whereas the magnetic flux leakage device detects internal defects such as corrosion or broken strands. This provides a more comprehensive assessment as the device identifies potential issues before they become critical.
