Ultra-Fast
Inspection of
Tubes up to 4”
COMPANY SNAPSHOT
Founded in 2010
Experts in Acoustic Pulse Reflectometry
Proven, patented Acoustic Eye technology
European presence and customer base
CE certified
ISO 9001 certified
www.soundtubetesting.com
BREAKTHROUGH TECHNOLOGY
Based on Acoustic Pulse
Reflectometry (APR)
Probe injects acoustic pulse down the tube
Returned echoes generated by defects are recorded
and analyzed
Patented algorithms identify and report exact location,
type and size of inner diameter defects

TODAY’S INSPECTION
Conventional inspection
techniques
Eddy Current – Electromagnetic test
Video Scope - Optic
IRIS - Ultrasonic
Slow, cumbersome, limited
Invasive
Application dependant – shape, material, size, thickness
Physical limitations – tube ID, wall thickness
Inventory of consumable probes and standards required
Requires highly skilled personnel
www.soundtubetesting.com
ACOUSTIC EYE SOLUTION
Up to 4” inner diameter, any shape or material
Boilers, Fin Fans, other heat exchangers
U-bends, twisted, spiral wound tubes
Ferrous and non-ferrous metals, graphite and plastics
Ultra-fast, non-invasive inspection
Less than 10 seconds per tube, 5 sec.< 20 ft.(6m)
Fast enough for 100% inspection if/when needed
Ideal for emergency situations
