Advanced technology hired for challenging inspection work

“When the project began, it was not possible to determine the exact period of time for which the inspection equipment would be required, so it made perfect sense to hire the equipment,” says JF NDT’s Ian Moore. “In addition, we knew that if we hired this kit from Ashtead, it would be delivered when and where we needed it, configured, calibrated and ready for work.”

In comparison with carbon steel, austenitic stainless steels have high ductility, low yield stress and relatively high ultimate tensile strength. Consequently, austenitic stainless steels are commonly employed in the aviation, surgical equipment, petrochemical and nuclear industries, for example. However, the inspection of welds in these applications requires the latest technology, coupled with skill and experience on the part of the inspection engineers.

The OmniScan^® MX2 is the latest in a line of ultrasonic flaw detectors that stretches back over 20 years. With high acquisition rates and powerful software, the next generation MX2 increases testing efficiency, ensuring superior manual and advanced AUT application performance with faster setups, test cycles, and reporting, in addition to universal compatibility with all phased array and ultrasound modules.

The inspection method allows the operator to size defects based upon a calculated curve for a given transducer, material, and reflector size, and has been designed to meet the requirements of international standards. This method only requires the operator to use one reference reflector in order to create a curve for flaw sizing.

Summarising, Ashtead Technology’s Neil Harrap says: “These probes were not previously included in our fleet of rental instruments and accessories, but we were very happy to acquire them so that JF NDT could conduct their initial work on the sample that their client had provided.

“It is very pleasing to note the success of this project, which exemplifies the benefits of our NDT Centre of Excellence – offering the latest technology with the highest levels of technical support.”
