Non Destructive Testing Services

SDC performs magnetic particle, dye penetration, and ultrasonic testing of all types of industrial structures including:

  • Tanks
  • Vessels
  • Ducts
  • Ladles
  • Lifting Beams
  • Corroded Structural Steel

The Non-Destructive testing is performed in accordance with inspection procedures developed for the major steel producers in the United States. The procedures include magnetic particle (MP) testing of fillet welds and ultrasonic Testing (UT) of the full penetration welds and pins.

In the Photo Gallery you will find a finite element model of the ductwork on top of a blast furnace.  The results of a comprehensive NDT inspection program of wall thickness testing were input into the FEA model.  SDC used our NDT Inspection and stress analysis capabilities to determine the corroded stress condition of the ductwork.   

Our Structural Inspection and Maintenance Management System (SIMMS) was then used to write the inspection reports, and develop condition based repair plans for the blast furnace.
