Non-Destructive Testing (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.
Dye penetrant inspection is designed to aid the visual inspection of surface breaking flaws such as cracks, porosity, seams and other surface discontinuities. It can be applied to both ferrous and non-ferrous materials and all non-porous materials (metals, plastics or ceramics).
Magnetic particle inspection is a surface inspection method used to aid the visual inspection of ferrous parts for surface breaking discontinuities. This involves first cleaning the part to remove any excess contaminants from the part surface which may mask any surface breaking discontinuities or interfere with the migration of magnetic particles during the test. This type of inspection is widely used as it can give an immediate indication of defects and discontinuities.
An ultrasonic transducer pulses sound into the inspection part at a given angle. Any discontinuities perpendicular to the inspection beam reflect the sound back to the transducer and form a response. Using multiple probes of differing angles, the technician can size the internal discontinuity, classify it, and plot its location within the inspection material to determine its compliance or inform production where to conduct the repair.
Ultrasonic thickness testing uses high-frequency sound to measure a material thickness with the use of specialist equipment and probes. Ultrasonic thickness inspection works by pulsing sound into the test part and “listening” for the echo response. The thickness is determined using the time taken for the sound to travel through the part as well as the known velocity of sound in the inspection material.
Eddy Current Testing is a versatile NDT method that can be used to detect (near) surface defects in conductive materials without removing the coating. An electromagnetic inductor is used to generate a magnetic field. Eddy Current testing is ideal for various on-site and plant inspections. Flaws can be reported immediately allowing for a more streamlined service between customer and client.
Copper sulphate (CuS04) Inspection is a chemical spot test used by QMS technicians to identify the presence of non-ferrous coatings on a ferrous substrate i.e. nickel plating on carbon steel.
Silver Nitrate (AgNO3) Inspection is a chemical test method used by QMS technicians to identify selective phase corrosion in NAB castings subjected to saltwater.
Radiographic Testing uses either x-rays or gamma rays to examine the internal structure of manufactured components identifying any flaws or defects.
The Silverwing RMS2 Scanner is a high speed, high accuracy remote access ultrasonic corrosion 3D mapping system with up to 50m long x 1m wide scan data acquisition feasible in one location. It is designed to evaluate the condition of ferrous structures such as storage tanks, pipelines, pressure vessels and other critical equipment and supports an efficient inspection program to ensure effective and safe operation.
