Advanced NDT

Phased array, TOFD, automated UT and digital radiography for faster decisions and a permanent digital record of every weld.

Overview

More data. Less downtime.

Advanced NDT gives more information per weld in less time. Our automated phased array and TOFD systems inspect the full weld volume in a single pass, while digital radiography (CR) replaces film with reusable imaging plates and digital images that can be enhanced, measured and archived.

For pipelines from 6" to 48" we run internal X-ray crawlers that expose each girth weld in a single panoramic shot from inside the pipe.

Methods

What we offer.

All methods are carried out by personnel certified to EN ISO 9712, on site or at our laboratory in Thessaloniki.

PAUT

Phased Array UT

Electronically steered beams image the weld cross-section, giving accurate defect location and sizing.

  • Sectorial & linear scans
  • Complex geometries, nozzles
TOFD

Time of Flight Diffraction

Diffraction-based technique for accurate through-wall sizing of flaws, regardless of orientation.

  • Accurate height sizing
  • Combined with PAUT
AUT

Automated UT of Girth Welds

Motorised scanners on a guide band inspect pipeline girth welds with PAUT and TOFD in minutes.

  • Mainline pipelines
  • Instant accept/reject
  • Full digital record
CR

Digital Radiography (CR)

Computed radiography with reusable phosphor imaging plates instead of film. Images are digital from the start, ready for review and archiving.

  • No chemicals or darkroom
  • Digital enhancement & measurement
  • Lower exposure times
CRW

Internal X-ray Crawlers

Crawlers travel inside the pipe and expose each girth weld panoramically from within.

  • 6"–18", 12"–26", 20"–48"
  • Single-wall single-image
DATA

Digital Reporting

Encoded data, images and reports delivered digitally for traceability and client sign-off.

Phased Array UT

Every weld, in data.

Encoded PAUT and TOFD channels from an automated girth weld scan: each zone of the weld is recorded, evaluated and archived for the client file.

Automated UT

Faster than film. Recorded for life.

On mainline pipelines our automated systems replace radiography on girth welds: no radiation exclusion zones, results within minutes, and a permanent digital record of every weld.
