Typical Applications
Dakota NDT instruments are used every day in the most demanding industrial sectors.
Oil & Gas and Petrochemical
Thickness measurement and corrosion monitoring to API 570 and API 653, reading through the coating and storing the data for corrosion-rate calculation.
Mechanical Engineering and Steelwork
Weld inspection with angled shear-wave probes and verification of the thickness declared by the supplier on incoming material.
Energy and Renewables
Measurement of the actual bolt load in structural joints and of the remaining wall thickness of piping and steam generators, within tight shutdown windows.
Marine and Offshore
Measurement of the metal on painted plating without removing the coating, with grid files for the mapping required by periodic class surveys.
Construction and Infrastructure
Remaining thickness of sections and plate measured through the paint, and inspection of structural welds on bridges, industrial buildings and water networks.
Chemical, Pharmaceutical and Food
Thickness monitoring from the outside, without opening or purging the process circuit, on stainless steels and small-diameter piping.
