Dacon inspection services provides a great range of advanced inspection techniques. The
priciples of these techniques are based on the latest technologies and the techniques offer
solutions for almost every inspection problem.
INCO test
RTD INCO test stands for Insulated Component test and offers quick inspection on insulated
components. This technique can be used for inspection of e.g. sphere legs, piping, vessels
and tanks without removing insulation.
Thermography
This technique converts invisible heat energy into a visible picture. The technique enables
the inspector to detect leakages and weak spots in insulation. Possible corrosion might
occur on locations where the insulation is weak.
Long Range Ultrasonics
This technique is as a rapid uiltrasonic screening technique for pipeline inspection. It
offers inspection in hard to acces areas, such as roadcrossings and risers.
Time Of Flight Diffraction (TOFD)
A quick and accurate ultrasonic technique to detect and size defects in welds. The
technique will be mainly used for inspection of new constructed components and the
acceptance of them but can also be used for detection of cracks and corrosion in used
components.
Positive Material Identification (PMI)
Dacon uses a portable analyser equiped with a x-ray tube instead of radio active isotopes.
This gives Dacon the possibility to provide low-cost on-site analysis of almost every material.
UT Crawler/ Rope Acces
For inspection on hard-to-acces areas Dacon can provide any kind of inspection using Rope
Acces or ultrasonic measurements using a magnetic crawler.
Magnetic Flux Leakage Tank Floor scanning
The floor scanner works on the MFL principle and provides quick screening of entire tank
floors. To prevent false indications from being reported, all indications found will be
verified with manual ultrasonic examination.
ACFM/ACPD
Alternating Current Field Measurement enables reliable crack detection and sizing on a wide
range of components. The technique can be applied on e.g. pipe butt welds, nozzles and
pressure vessel seam welds.
Acoustic Emission
Acoustic Emission can be used to screen the condition of pressure vessels or tanks while
they are in service. Acoustic emission gives a general indication about the condition of
the object under test and localisation of defects is limited. |
