ON-LINE Acoustic Emission Inspection

Advanced Acoustic Emission (AE) Inspection ON-LINE or Off-Line

SENTRO TECHNOLOGIES USA, LLC specializes in Acoustic Emission Inspection and Testing, which can be performed ON-LINE during normal operating conditions.

Acoustic Emission (AE) is a phenomenon of sound and ultrasound wave radiation in materials that undergo deformation or fracture processes.

Cracking, plastic deformation development, fracture and de-bonding of hard inclusions are examples of macroscopic sources of AE in metals.

Friction and impacts are examples of mechanical AE sources.


Detection of corrosion products by AE method




Applicable for:

• Piping – metal, concrete, plastics – all sizes, above ground or under ground
• Heat exchangers
• Storage tanks, including hazardous material
• Pressure vessels, including  towers and reactors
• Isolated equipment
• FRP (Fiberglass) equipment (vessels, pipes)
• Glass lined equipment

Absolute identification of flaws and  defects – size and location:

• Corrosion
• Micro-cracks
• Holes
• Blockages
• Deformation

 Detection of micro-cracks by AE method

• ASTM – American Society for Testing and Materials
• ASME – American Society of Mechanical Engineers
• European Committee for Standardization
• International Organization for Standardization
• Japanese Institute for Standardization
• Japanese Society for Nondestructive Inspection
