End CUI Guesswork. Meet MULTIPHONON

Corrosion Under Insulation (CUI) remains one of the most costly and unpredictable threats to asset integrity in industrial facilities. Hidden beneath insulation, corrosion often progresses undetected until it leads to leaks, unplanned shutdowns, or safety incidents.

In this video, we present MULTIPHONON, a proven non-intrusive, in-service inspection technology designed to eliminate uncertainty in CUI detection — without insulation removal, shutdowns, or disruption to operations.

The Challenge of CUI in Industrial Assets

CUI is responsible for a significant percentage of piping and equipment failures across oil & gas, petrochemical, and process industries. Traditional inspection approaches rely on sampling, insulation stripping, scaffolding, and shutdowns — often providing limited coverage and reactive results.

As a consequence, asset owners are frequently forced to estimate risk rather than measure it, increasing both operational and financial exposure.

How MULTIPHONON Eliminates CUI Guesswork

MULTIPHONON uses patented phonon-based inspection technology to detect active corrosion and structural defects inside metallic assets. By analyzing how vibrational energy propagates through the material’s crystal lattice, MULTIPHONON identifies areas where corrosion, cracks, or stress-related damage are actively developing.

This approach allows for:

• Early detection of active CUI

• Full asset coverage, not just sampled areas

• In-service inspections under normal operating conditions

• Accurate defect localization and sizing

• Non-Intrusive, In-Service, and Scalable

MULTIPHONON inspections require minimal preparation and can be performed on:

• Insulated pipelines and piping systems

• Pressure vessels and reactors

• Storage tanks, including tank bottoms

• Offshore risers and complex structures

Using Linear, Planar, and Volumetric inspection modes, MULTIPHONON adapts to different geometries and asset configurations while maintaining continuous metallic signal paths.

Key Benefits Over Traditional CUI Inspection Methods

• No insulation removal (except at sensor locations)

• No shutdowns or production losses

• Reduced manpower and safety exposure

• High Probability of Detection (POD > 80%)

• Faster inspections and reporting

• Significant cost savings vs. conventional NDT

• Proven in the Field

MULTIPHONON is a field-proven technology, independently verified and adopted by major operators worldwide. It has been successfully deployed on FPSOs, offshore platforms, refineries, and terminals, delivering reliable results with measurable reductions in downtime and inspection costs.

By replacing assumptions with measurable, data-driven insight, MULTIPHONON enables asset owners to make informed integrity decisions with confidence.
