Since 1973 we have inspected welds on pipelines, power plants, compressor stations, tanks and pressure vessels. Today our crews cover every conventional NDT method, from radiography with X-ray and gamma sources to surface methods, hardness and positive material identification.
Our radiography facilities and equipment are licensed by the Greek Atomic Energy Commission (EEAE). Mobile darkroom trucks with automatic film processors let us deliver radiographic results on site, the same day.
All methods are carried out by personnel certified to EN ISO 9712, on site or at our laboratory in Thessaloniki.
Volumetric inspection of welds with X-ray and gamma sources, external or with internal pipeline crawlers.
Detection and sizing of internal flaws in welds, plates and forgings with conventional flaw detectors.
Wall thickness surveys for corrosion monitoring and acceptance of pipes, tanks and vessels.
Surface and near-surface crack detection on ferromagnetic materials with electromagnetic yokes.
Detection of surface-breaking defects on any non-porous material, including stainless steel and alloys.
Visual examination of welds and components before, during and after fabrication.
Portable ultrasonic (UCI) hardness measurement of welds, HAZ and base metal, on site.
Alloy verification with handheld XRF analysers, so the right material ends up in the right place.
Leak testing of tank bottoms and welded seams with vacuum boxes.
Detection of defects in insulating pipeline coatings before backfilling.
