Advanced NDE Anomaly Investigation

IAG has been an industry leader with new technology adoption to improve both the efficiency, and the accuracy when measuring anomalies identiﬁed through traditional or enhanced inspection programs. By understanding the morphology of the anomalies and the materials that the exist within our SME’s can provide an optimal inspection plan. The di9erent Advanced Tools listed below are capable of being used as; semi-automated, mechanized, or robotically integrated platforms to meet the requirements of our customers.

Metal Loss Anomalies

Metal loss anomalies can be contained throughout the volume of the piping, tanks, and vessels that are inspected by the various IAG Inspection teams and inspectors. As such, there is always a combination of technologies and techniques from Ultrasonic, Laser, and Eddy Current based disciplines that can be applied to best achieve the target data being delivered to the end customer and their Engineering teams to support calculations and repair decisions being made. Below are some of the most deployed tools and technologies to solve these detection and sizing needs today:

Automated Ultrasonic Testing (AUT) Corrosion Mapping

Phased Array Ultrasonic Testing – Welds / Corrosion Mapping

PAUT TFM/FMC Scanning & Sizing – Welds / Corrosion Mapping

Guided Wave Ultrasonic Testing – Long Range / Medium Range / Short Range Screening

Pulsed Eddy Current Array (PECA) Scanning through Insulation

3D Laser Mapping Creaform Systems – Same Surface Scanning

Structured Light 3D Surface Mapping – Same Surface Scanning – Integrated with BIKE

Cracking or Surface Breaking Anomalies

Surface breaking anomalies can be as simple as gouges or slivers and they can be as complex as Intergranular Stress Corrosion Cracking. These crack-like anomalies are contained throughout the volume of the parent material and the welds of the various piping, tanks, and vessels that are routinely inspected by the various IAG Inspection teams and inspectors. There is never one solution that will satisfy every anomaly type, and as a result the use of a combination of technologies and techniques from Ultrasonic, and Eddy Current based disciplines will best achieve the needs of our end customers and their Engineering teams as they manage their repair decisions matrices. Below are some of the most effective advanced tools and technologies to solve these detection and sizing needs today:

Phased Array Ultrasonic Testing – Welds / Corrosion Mapping

PAUT TFM/FMC Scanning & Sizing – Welds / Corrosion Mapping

Time Of Flight Diffraction (TOFD) – Welds / Complex Geometry / In Combination

Guided Wave Ultrasonic Testing – Long Range / Medium Range

Eddy Current Arrays (ECA) Spyne Scanning – Detection & Distribution Mapping

ENHANCE your traditional MPI / MT inspections
Finds Pitting / Cracking / Hard Spots in same data set

Tangential Eddy Current Array (TECA) Sharck Sizing Probes – Instant Sizing down to 0.120in

ENHANCE your Crack Sizing and Focus PAUT resources to deepest areas

Mechanical & Other Material Property Based Anomalies

Mechanical damage such as dents, ﬂat spots, hard spots, buckles, and wrinkles have all changed the physical properties of the materials when they were produced. The impact of these mechanical property changes cannot always be determined by the physical appearance of these defects, nor can the presence of these property changes be readily visible to the naked eye and the screening tools being used to identify them. The following advanced technologies are applied to help conﬁrm the location or presence of these mechanical property changes, as well as to accurately deﬁne the extent of these changes to the material itself. These tools can be used independently or in combination depending on the complexity of the damage that has been identiﬁed by a susceptibility model, material trend, or screening inspection performed on a speciﬁc population of assets:

Eddy Current Arrays (ECA) Spyne Scanning – Detection & Distribution Mapping

3D Laser Mapping Creaform Systems – Same Surface Scanning

Structured Light 3D Surface Mapping – Same Surface Scanning – Integrated with BIKE

Frontics AIS 2100 Instrumented Indentation Testing (IIT) Tooling – Pipe Grade & Hardness
