Acoustic Emission Testing & Corrosion Coating

Acoustic Emission Testing

“Acoustic Emission Testing (AE) is a non-destructive testing technique that “listens” to a material under stress. A crack/flaw in a stressed structure will emit sounds. AE sensors “hear” these sounds and computers are used to record, analyze the severity and pin point the location of the flaw.”

Services Applicable to the following Industries:



Stress Corrosion Cracking:

Detects the early stages of stress corrosion cracking

Structural Monitoring:

Areas that are difficult to inspect can be monitored for cracks

Leak Detection / Leak Control

  • Tubes Skids / Gas Cylinders:
  • Acoustic emission procedure has been used during normal filling to identify defects

Specialised Inspections:

  • Complete Aerial Lift Device Inspections on insulated and non-insulated mobile elevating working platforms
  • Six monthly survey of all Lifting equipment in accordance with national regulations

Plant Condition Management Systems (PCMS)

Utilised in many refineries, chemical plants, production and exploration facilities for the management of inspection information on piping, pressure vessels and other equipment


Civil Structures

Structural monitoring and material testing applications and techniques:

  • Steel Structures
  • Concrete Structures
  • Wire Break Monitoring
  • Roads - listening to materials and the characteristics thereof


Power Transformers

Acoustic Emission Systems can be used to detect and/or locate PD (partial discharge) in transformers


Complete Aerial Lift Device Inspection

“Procedures are used to determine the overall condition and structural integrity of the aerial lift device, as well as determine whether or not the aerial lift device is safe to operate in a working environment.”


Pulp & Chemical Services

Detecting defects and damage in metal and composite equipment


Services Applicable to the following Industries:



TankPac - Tank Floor Monitoring

Is a ‘sorting’ system which separates 'Good’ tanks from ‘Bad’ and thus directs maintenance to where it is most needed. The method listens to active corrosion and can give you a good picture of the condition of the tank floor without taking the tank out of service.



Used for in-service testing of LPG spheres, cryogenic tank walls and stainless steel plant. The test consists of attaching sensors to the outside of the equipment and monitoring for acoustic emission resulting from cracking, yielding and corrosion, during a controlled change in stress.


IRT - Sphere Leg Test


TALRUT (Tank Annular Ring)

“A critical part of any storage tank is the annular ring area; severe damage here can lead to major structural failure with consequential rapid loss of contents. We developed an automated ultrasonic scanner, software and procedure to assess this area without the tank needing to be removed from service.”
