SpirALL® Electromagnetic Acoustic Transducer (EMAT)

spirall-electromagnetic-acoustic-transducer

Technology Type

emat-icon

Detection Capabilities

Coating and Lamination Anomalies
  • Coating Disbondment
  • Mid-Wall and Surface Breaking Laminations
Mill Anomalies
  • Lack of Fusion
Construction-Weld Anomalies
  • Cold Weld
  • Hook Crack 
  • Seam Variations
Interactive Pipeline Threats
  • Stress Corrosion Cracking (SCC)
  • Selective Seam Weld Corrosion (SSWC) 
  • Mechanical Damage
Crack Anomalies
  • Axial Crack
  • Longitudinal Seam Weld Crack
  • Spiral Seam Weld Crack
Environmentally Assisted Crack Anomalies
  • Fatigue Crack
  • Hydrogen Induced Cracking (HIC)

Designed to enhance in-line inspection and give pipeline owners and operators more confidence about inspection results for crack detection, SpirALL® Electromagnetic Acoustic Transducer (EMAT) technology finds anomalies that magnetic flux leakage-based technology is unable to detect.

SpirALL EMAT technology can be used in either liquid or gas pipelines without requiring a couplant.

Combining SpirALL EMAT data with data produced by the various technologies on the Multiple Dataset (MDS) platform enables more accurate characterization of pipeline defects. 

Key Features

  • Innovative design produced redundant data across multiple channels to reduce the likelihood of false or irrelevant data being erroneously recorded as a defect
  • Data correlation with MDS eliminates false calls for non-critical features and delivers all pipeline features and anomalies in a single report

Sizes

  • 10-inch through 16-inch
