Corrosion Mapping (EMAT & PAUT)

Corrosion mapping with quantitative measurement of the thickness of the remaining wall. EMAT provides a non-contact, no-couplant, single-sensor measurement. PAUT provides a traditional ultrasonic solution with conventional UT sensors.

EMAT sensors are ideal for measurements on rough/coated metallic components with mostly internal corrosion (heavy external corrosion or gauges could limit efficacy due to excessive lift-off). Conventional Phased-Array UT (PAUT) systems provide great accuracy with internal and external corrosion thanks to water coupling.

Features

EMAT

  • Non-contact EMAT technique.
  • Highly efficient on coated and rough surfaces. Provides measurements without couplant.
  • Patented pulser and custom transducer provide measurements 2mm (0.080”) from the entry wall.
  • Highly efficient for areas with internal corrosion.
  • Roller kits, encoders and adaptors for different applications.

UT/PAUT

  • Conventional UT transducers using couplant.
  • Permit covering large areas using phased arrays.
  • Roller probe available for couplant-less applications.
