Conventional PAUT

A phased array system is normally based around a specialized ultrasonic transducer that contains many individual elements that can be pulsed separately in a programmed pattern.
Applications:

– Weld Quality inspection.
– Flaw characterization and critical sizing.
– In service inspection, environmental crack detection.
– HTHA detection.
-Encoded nozzle weld inspection.
-Localized Corrosion Mapping.
– PSA vessel crack detection.

MUT Shear Wave

Shear wave testing, also known as angle beam inspection, is an ultrasonic testing technique used primarily for weld inspections.
A probe consisting of an ultrasonic transducer coupled with a plastic or epoxy wedge introduces an ultrasonic beam at an angle into a test area.
Applications:
– ASME and AWS Weld Quality inspection.
– Flaw characterization and critical sizing.
– In service inspection, environmental crack detection ad sizing.

AUT Corrosion Mapping

Corrosion Mapping ultrasonic testing maps the interior surface of pressure vessels, piping, heat exchangers, and more.

It is often used for remaining life determinations as prescribed by the facility’s Mechanical Integrity program.

Application:
– Corrosion monitoring and detection on vessel and piping.

Conventional TOFD

Although time-of-flight diffraction (TOFD) can be used for a variety of applications, its primary use is rapid weld testing of circumferential and axial weld seams, also known as perpendicular TOFD scanning
Application:

– Weld Quality in leu of RT inspection.
– In-service inspection, environmental cracking detection.
– Defect critical sizing and monitoring.
– HDPE fusion weld Inspection.
– Preferential corrosion detection and sizing.

Tanks Inspection Solution

Multi Skip PAUT and SRUT-GW for critical zone
Thanks to the very powerful Phased Array Pulser-Receiver electronics allowing the full aperture emitting and receiving of ultrasonic signals PAUT Scope instruments may be used for the Short Range Guided Wave (SRUT) inspection and corrosion screening.

Applications:
Corrosion screening on:
Annular ring of above ground storage tank.
pipe walls under insulation.
Above pipe supports.
and in interface areas (Air-soil, Vapor-Product)

Tanks Floor Scanning with MFE

Magnetic Flux Leakage (MFL) A powerful magnet is used to magnetize the steel. In areas where there is corrosion or missing metal, the magnetic field “leaks” from the steel.

MFL tools use sensors placed between the poles of the magnet to pinpoint the leakage field.

Liquid Penetrant Testing

Examination using liquid penetrants (PT) allows discontinuities which are present at the surface of the part under examination to be detected.

High Temperature Hydrogen Attack (HTHA) Detection

Test screening will be performed using Time Of Flight Diffraction (TOFD). HTHA damage like indications will be confimed using Phased array Ultrasonic Testing (PAUT), TFM and AUBT.

Dimensioning

Assesses and confirm through the measurement the geometric characteristics of machined parts and products to verify their compliance with design specifications. Dimensional inspection services ensure the accuracy of the product features that can affect reliability and functionality.
Inspection is often a critical step during product development or or when the part needs to be reused.

Magnetic Particle Testing

Examinations using magnetic particles (MT) is based on the fact that when a test piece is magnetized its surface and near surface discontinuities cause the dispersion of certain magnetic flux (leakage flux).

Total Focusing Method (TFM)

The Total Focusing Method (TFM) is an ultrasonic array post-processing technique which is used to synthetically focus
at every point of a region of interest.
– HTHA detection, detection and confirmation.
– Environmental cracking detection, characterization.
– Defect critical sizing.
– Bolt inspection.

HARDNESS

Hardness Testing (HT).

Material Hardness Testing determines a material’s strength by measuring its resistance to penetration. Hardness test results can be extremely useful when selecting materials, because the reported hardness value indicates how easily the material can be machined and how well it will wear. Hardness testing is a critical NDE tool utilized to ensure that the welding, heat treatment and fabrication methods have not altered the original material of construction in a deleterious way.

Field Metallurgical Replication

FMR is an NDT metallurgical inspection technique that is used for evaluating plant equipment such as heaters, boilers, piping and reactors.

FMR is a simple process, Using portable equipment, the metal surface is ground and polished to a mirror finish. The polished surface is subsequently etched to reveal the microstructure.
A replica of the etched surface is then made with a thin piece of acetate film.
The replica can then be examined back in the field using a portable optical microscope or in the laboratory.
This process gives our metallurgical engineers the ability to examine microstructural features such as grain size, cracks, carbides, creep and other damage mechanisms. It can confirm observations made by other non- destructive methods such as acoustic emission tests, penetrant examination and ultrasonic flaw detection and take it a step further to identify the nature of the flaw.
