NORDISCAN PL

NORDISCAN-PL

Systems for Automatic Ultrasonic off-line Examination of Plates

The NORDISCAN-PL series Scanners are intended for fully automated off-line ultrasonic examination of body and edges of plates, coils, slabs, and ingots.

NORDISCAN-PL systems are designed to perform fully automatic high performance inspections of flats outside of the production line on a charging table.

The system utilizes our advanced software and displays the defect map in real-time mode, and simultaneously saves the results on a local or external drive for further evaluation, re-evaluation and analysis. 

.

The EMATEST-PL series achieves multiple inspection tasks:

  • Detection of internal imperfections in rolled plates, ingots, and slabs such as: laminations, non-metallic inclusions, porosity, shell, sponge, etc.
  • Detection of surface and sub-surface defects;
  • Detection of zones of mechanical properties uniformity (Hard Sports);
  • Precise wall thickness measurement;
  • Plate Geometry Monitoring.

.

Typical Specification of Plates to be Tested:

  • Width: 1000 mm – 6000 mm;
  • Length: from 1000 mm;
  • Thickness Range: 3 mm – 350 mm;
  • Material: carbon steel; stainless steel; aluminum, titanium, cooper and alloys;
  • Surface Temperature: up to 250 o

Main Ultrasonic Testing Parameters

  • Test Sensitivity:
    • For internal imperfections: equal to FBH 2*;
    • For surface imperfections: equal to notches 0.2 mm x 10 mm (D x W);
  • Wall thickness measurement accuracy: +05 mm;
  • Capacity of Testing: 200 s (calculated for plate 4 m x 12 m)
*Depending of material to be tested and its surface condition

Ultrasonic Testing Standards:

  • Density of Ultrasonic examination, test procedures, acceptance criteria, data processing and representation adhere to multiple international and local standards such as: GOST 22727, SEL 072, ISO 12094, API 5L, ASTM 435, ASTM 578, DNV-OS-F101, EN10160, JIS0901, JIS0801, ISO10893, ISO3183
  • Testing and acceptance criteria can be customized based on client specific needs and new standards.

Type  of Applied Multichannel Ultrasonic or Eddy Current probes:
