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 …
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, …
The Total Focusing Method (TFM) is an ultrasonic array post-processing technique which is used to synthetically focusat every point of a region of interest. – HTHA detection, detection and confirmation. – Environmental cracking detection, characterization.
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).
Examination using liquid penetrants (PT) allows discontinuities which are present at the surface of the part under examination to be detected.
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.
Multi Skip PAUT and SRUT-GW for critical zoneThanks 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. …
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 …
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.
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 …
