- Magnetic particle testing
- Penetrant testing
- Ultrasonic testing
- Phased array
- Time-of-Flight Diffraction
- Hydrostatic testing
- Certified welding inspectors
- Quality assurance & Quality control (QA/QC)
- Third party inspection
- Risk based Inspections
Non-destructive testing (NDT) is a wide group of analysis techniques used in industry to evaluate the properties of a material, component or system without causing damage, therefore saving time and money in product evaluation and research. Whether you are a fabrication shop requiring weld inspection or a foundry producing castings or production facility looking at verification of plant. We are qualified and NATA endorsed to test your product or design an inspection program to track the reliability of your plant.
Visual Inspection: is the most important inspection method despite being relatively overlooked. It is regarded as the primary inspection method for welds. This because many of the indications discovered are particularly important, and yet easy to correct. In addition many surface defects may interfere with other NDT methods.
Liquid Penetrant testing: or dye penetrant is a technique that reveals surface imperfections by bleed-out of penetrant against a contrasting developer. Properly performed the technique is very sensitive and is capable of revealing cracks as small as 0.2 mm in length. The technique is relatively simple in concept, but must be properly performed to be effective.
Magnetic Particle Testing: is based on detecting distorted magnetic fields that occur near a flaw in a magnetized ferromagnetic material. The distorted magnetic field around a surface or near surface flaw causes flux leakage, a condition that causes magnetic particles to accumulate, revealing the flaw.
MT can be used with the application of fluorescent or colour contrast particles.
Ultrasonic Testing: is a technique that uses high frequency (Ultrasonic) sound beams to locate flaws inside of, or at the surface of solid objects. It can also be used to measure material thickness and wear, determine material properties such as elastic moduli and measure stress. The most commonly used technique is to transmit pulses of sound from the probe into object tested and to analyse the reflected sounds to locate, characterize and size flaws in the test piece. Other ultrasonic techniques include ToFD – Time of Flight Diffraction and PAUT Phased Array.
Time of Flight Diffraction (ToFD): is an ultrasonic technique that uses the time of flight of an ultrasonic pulse rather than amplitude as in pulsed echo. Although time-of-flight diffraction (TOFD) can be used for a variety of applications, its primary use is rapid weld testing of circumferential and axial weld seams. It is often coupled with Phased Array in order to cover root and cap regions of a weld.
Phased Array: is an ultrasonic technique beams of sound can be manipulated to sweep like a search light through the object being examined. When the data from multiple beams is put together a visual image showing a slice through the object is obtained. The technique is widely used in the Power generation, Petrochemical and construction industries to determine component failure and in service quality. Corrosion mapping, and weld integrity are two of the far-reaching applications in which Phased Array can be used.
Hydrostatic Pressure testing: is a test in which the vessel is filled with an incompressible liquid, Pressured to a pre determine test pressure and checked for leaks and distortion of the component using a variety of visual aids. Most commonly used on pressure piping and vessels.
