NDT & INSPECTION SERVICES
National Test is proud to offer clients the highest level of NDT and Inspection Services backed by competent technical staff, quality consumables, equipment and tools, and the ongoing training and development of staff.
Our staff provide industrial radiographic inspections using X-ray and gamma ray apparatus. All film processing is undertaken using automated equipment and our mobile field laboratory is fitted with a modern automatic film processor. We can also provide longer-term onsite processing and reporting using our two 20’ Sea Container Laboratories. Common uses include:
- Pipe spooling
- In-service equipment (valves, piping, nozzles)
- Internal corrosion detection and monitoring
Using digital ultrasonic equipment, our qualified personnel are capable of accurate pulse-echo flaw detection, monitoring and evaluation. These inspections can be carried out on:
- Static or in-service components
- Monitoring of discontinuity propagation
- Thickness surveys
- Lamination detection
Using the latest in AC Yoke Magnetising Units, our accredited technicians are capable of both fluorescent and visible magnetic particle inspection. This method is useful for:
- Surface and sub-surface defects in ferrous materials
- Thread and gear testing
Utilising the best consumables, our staff can conduct testing using fluorescent and visible dye penetrant methods. Dye penetrant testing is beneficial in the testing of surface defects in non-ferrous materials such as aluminium, stainless steel, copper and ceramics.
Utilising portable Leeb Hardness Test equipment, National Test can report and convert data to Rockwell C, Rockwell b, Brinell and Vickers formats. Hardness Testing is often required for:
- Material classification by comparative hardness evaluation
- Verification of Post Weld Heat Treatment procedural compliance
- Non Destructive and non invasive test method
Our technicians are able to offer reliable PMI using the latest XRF technology from Olympus. Using a vast on-board library of alloys and specifications, our XRF devices can identify material grades and specific chemical compounds.
Our AICIP Inspectors can undertake in-service pressure vessel inspections for:
- Oil and gas, power and industrial assets
- Statutory vessel inspections and vessel certification
- Remnant life assessment to be removed
