Providing a complete inspection solution tailored to suit any environment or scope
SRG Global are NATA Accredited to complete multiple methods of Non-Destructive Testing (NDT).
NDT covers a diverse range of techniques designed for assessing the integrity of materials, most typically metals. Applications include evaluating compliance of fabricated items with material specifications and identifying degradation which can occur during the service life of equipment or structures.
SRG Global can provide ultrasonic examination of both welds (UTW) and thickness (UTT).
UTW involves ultrasonic examination of materials and flaw detection in materials (i.e. welds, castings, forgings and other wrought products). UTT involves wall thickness measurements and corrosion mapping.
Magnetic Particle Inspection (MPI) involves detection of surface and sub-surface discontinuities in ferrous materials (magnetic materials) and can also be undertaken using fluorescent UV light. MPI is a very sensitive test method which can detect tight in-service fatigue cracks in rotating parts or creep cracks. This method cannot be used for non-ferrous materials or nonmagnetic ferrous materials such as austenitic stainless steels.
Eddy Current Inspection (ECI) involves electromagnetic examination of materials used to detect very small cracks in or near the surface of the material, with the surfaces requiring minimal preparation. The biggest advantage of this inspection method is it can be used to determine surface flaws on painted or coated surfaces. Eddy Current flaw detection is commonly used in the aerospace, crane and concrete pumping industries, as well as other general industries where the protective surface coating cannot be removed.
Dye Penetrant Inspection (DPI) is an inspection method to detect surface-breaking discontinuities in all non-porous materials such as stainless steel, aluminium etc. This inspection method can also be undertaken using fluorescent UV lights.
Laser profilometry (scanning) is a non-contact, non-destructive technique used to scan and map the surface of an object. Laser scanning is a viable NDT tool for a number of applications in the processing industries, including pipeline, boiler tube and coke drum inspections. Laser scanning is often used as a follow-up procedure to in-line inspection in order to help validate any detected corrosion or other forms of material degradation. One major advantage of this method is it’s speed. It is able to gather substantial quantities of accurate data much more quickly than other more traditional methods.
Long Range Ultrasonic Testing (LRUT) is an advanced non-destructive examination technique developed for testing large volumes of material form a single test point. LRUT is one of the fastest inspections tools for carrying out pipeline surveys for corrosion and other damage mechanisms. LRUT can be utilised as a test method for Corrosion Under Insulation (CUI), which is any type of corrosion that occurs due to moisture present on the external surface of insulation equipment. The damage / attack can be caused by one of the multiple factors, and can occur in equipment operating at ambient. Low and heated services, depending upon conditions. Moreover, CUI can occur in equipment that is in service, out of service, or in cyclic service.
Phased Array Ultrasonic Testing (PAUT) utilises a set of ultrasonic testing probes made up of numerous small elements, each of which is pulsed individually with computer-calculated timing. This technique can be used to inspect more complex geometrics that are difficult and much slower to inspect with single probes. PAUT can be used to inspect almost any material where traditional UT methods have been utilised, and is often used for weld inspections and crack detection.
Time of Flight Diffraction (TOFD) is used to look for flaws in welds. TOFD uses the time of flight of an ultrasonic pulse to find the location of a reflector. It can also be used for weld overlays and the heat affected zones of other components as well such as piping, pressure vessels, clad material, storage tanks and structural steel.
