Non Destructive Testing (NDT)
Tasman Rope Access established a Non-Destructive Testing department in 2015. NDT is the safe examination of materials and assets in a method that does not damage plants or equipment. Tasman Rope Access technicians are accredited to both the Australian Institute of Non-Destructive Testing and the British Institute of Non-Destructive Testing and provide a range of wear management solutions and asset integrity inspection services.
Since 2015, Tasman has developed expertise in structural integrity inspections, life extension surveys, corrosion mapping, weld scanning, visual inspections as well as asset condition and monitoring. By providing detailed NDT inspection reports, Tasman Rope Access assists our clientele in the execution of safe and cost-effective maintenance planning and repair solutions. The added advantage of completing this work via rope access eliminates the requirement for bulky equipment like EWP & Scissor Lift equipment thus reducing the inherent cost with mobilisation and demobilisation.
Ultrasonic testing methods conducted by Tasman include thickness testing, corrosion mapping, lamination detection, weld testing, and wear management reporting. These inspection methods are utilised to inspect the fixed plant, sacrificial wear liner thickness, heavy machinery, ball mills, tank inspections, process piping, and structural steel components.
Magnetic Particle Testing
Magnetic Particle Testing Inspection (‘MPI’) has developed into an NDT method for the detection of surface and shallow sub-surface discontinuities in ferrous materials. The test method involves the application of a magnetic or electric current that passes through the material.
Eddy Current Testing
Eddy current testing as an NDT method allows technicians to discover indications without having to remove protective coatings. This allows for significant cost savings and safety innovations. Eddy current surface flaw detection in welds and stress points is commonly used on machinery like cranes, car dumpers, and rock breakers.
Dye Penetrant Inspection (‘DPI’ or ‘PT’) is used to detect surface breaking flaws in all non-porous materials such as metals, plastics, and ceramics. This is a cost-effective method of identifying discontinuities such as cracks, porosity, laps, and seams. Dye penetrant is commonly used to test lifting lugs, stainless steel weld joints, wind turbine blades, forgings, and castings.
Radiographic testing (RT) uses either X-rays or gamma radiation to create images to examine the internal structure of components for flaws or defects. Industrial radiographic testing is commonly used to ascertain the integrity of welds, castings, piping, mechanical parts, and pressure vessels. It is advantageous because it requires very little surface preparation, can test both surface and sub-surface, and can be used on many different material types.
