NDT INSPECTION
REEL specialises in Non Destructive Testing (NDT) using the following disciplines:
Magnetic Particle Inspection (MPI)
MPI is a proven and reliable method of detecting even the smallest surface, or near-surface, flaws in ferrous materials.
The MPI inspection equipment establishes the magnetic field pattern of the material and pinpoints cracks by identifying any distortion in that field. Cracks cause leakage of magnetic flux in the vicinity of the flaw and the equipment identifies build-ups of very fine iron particles that gather at the location of the leakage, however small it may be.
Dye Penetrant Inspection (DPI)
DPI is a simple method of detecting surface-extruding flaws such as cracks or porosity. One step up from visual inspection, DPI offers advantages of large area coverage, speed and low cost.
Based on the principle that liquid is drawn into a surface-breaking crack by capillary action, dry powder developer is applied to the surface to draw out the liquid that has penetrated the crack and produce a surface indication.
Eddy Current Inspection
Eddy Current Inspection is used to detect surface-exuding defects such as fatigue without having to remove protective coatings by grit blasting or needle gun. REEL has successfully applied this technique in the offshore industry worldwide over many years.
Ultrasonic Inspection
This effective method produces quick, highly sensitive results and can be used on most materials if sound transmission is good. High frequency sound pulses are emitted from a transducer above a sample of the material. The sound waves propagate through the sample, reflecting at interfaces and these reflected waves are monitored by a detector above the sample. The depth and type of flaws are ascertained using this method. The testing is carried out from one side of the sample only.
