Non Destructive Testing page


Non-Destructive Testing (NDT) is a wide group of analysis techniques employing specific methods to evaluate the condition of plants and equipment without causing damage. It is carried out at all stages of the asset life cycle from the construction of plant and equipment through to regular testing during planned downtime or at set intervals throughout its asset life.

Rapallo can advise on the most suitable NDT for your plant and equipment. Our NATA accredited ISO 17025 NDT department provide a suite of specialised services. Rapallo can provide the following NDT Services;

Visual Inspection

Rapallo’s technicians have decades of experience in the industry and can quickly and efficiently perform a visual inspection of any welds, castings, forgings or rolled products and let you know exactly whether a further investigation or other NDT methods are required.

Magnetic Particle Inspection

Magnetic Particle inspection is a commonly used non-destructive testing method for finding cracks and other surface level flaws in iron, steel, and other ferromagnetic material. It works by drawing magnetic particles to any flaws or defects found on the material. Not all indications are defects however, Skilled NDT personnel are important when it comes to interpreting MPI results. Rapallo‘s team of NDT technicians have decades of experience in MPI contact us now for further information.

Ultrasonic Thickness Testing

Ultrasonic thickness testing is a commonly used non-destructive testing method for determining the wall thickness of a solid element and detecting weld discontinuities. Our team of NDT technicians have been using Ultrasonic thickness testing to determine the structural integrity of pressure equipment, tanks, pipework and other equipment for decades now. Contact us now for further information or to book in an Ultrasonic thickness assessment.

Dye Penetrant Testing

Dye penetrant is commonly used to detect surface discontinuities in non-ferrous materials. It works by allowing fluid to penetrating and build up within discontinuities, after a period of the time the excess dye is removed for the test piece and a developer is applied that reveals the indication to the inspector. Dye Penetrant is one more NDT method that Rapallo keeps in its toolbox of tricks to determine the integrity of an asset. Contact us now to book in an NDT inspection.

Thermal Imaging

Rapallo’s FLIR T335 Thermal Imaging camera can be deployed out of our Kalgoorlie office and can be used to detect a number of mechanical and electrical problems before a break down occurs. Infra-red imaging picks up hot spots on electrical circuit boxes, bearings and motors so that preventative maintenance can be planned and implemented before any costly unscheduled downtime occurs.

Acoustic Emissions Testing

Rapallo are the only in-house provider of Acoustic Emissions testing in Western Australia. This technology monitors sound waves to detect discontinuities, allowing you to determine the location of potential points of failure in your equipment. Our team can perform integrity assessments, condition monitoring and AS2550 inspections of Fibreglass crane booms along with the rest of your AE testing needs.
