CONVENTIONAL NDT

RADIOGRAPHIC TEST

This technique contains the use of penetrating gamma or X-radiation to examine parts and products for imperfections. An X-ray machine or radioactive isotope is used as a source of radiation. Radiation is directed through a part and onto film or other media. The resulting shadowgraph shows the internal soundness of the part. Possible imperfections are indicated as density variations in the film.

ULTRASONIC TEST

Ultrasonic Testing (UT) uses high frequency sound energy to conduct examinations and make measurements. Ultrasonic inspection can be used for flaw detection/evaluation, dimensional measurements, material characterization, and more.

UT THICKNESS MEASUREMENT

They work by measuring the time interval between the excitation pulse that generates the sound wave and the first returning echo. The material wall thickness is derived from the relationship between the time of flight of the ultrasonic pulse and the velocity of the sound in the material.In this ultrasonic thickness gauge working principle, pulses are reflected by the probe when they are in contact with an object's material through its surface. Once the pulses are reflected, the thickness of an object can be measured.

MAGNETIC PARTICLE TESTING

Magnetic particle inspection (MPI) is a Non Destructive Testing process where a magnetic field is used for detecting surface, and shallow subsurface, discontinuities in ferromagnetic materials.

PENETRANT TESTING

Liquid or dye Penetrant testing (PT) is a non-destructive material testing method which uses capillary forces to find surface cracks or pores and make them visible. It can detect surface-breaking flaws such as cracks, laps, porosity.

ADVANCED SOLUTION

Advanced NDT team of Mantek Arabia helps you to inspect complex geometries, much faster than ever before with high degree of repeatability. With PAUT is we create detailed and accurate cross- sections of a part to make it easier and ready for further deep study and analysis. It is also particularly useful in situations where there is less room for mechanical scanning because it’s able to sweep the beam without moving the probe.

Mantek Arabia NDT is equipped with latest PAUT/ TOFD machines and accessories from iconic brands around the world, we also have served a good number of clients in India, Middle East, South East Asia and African countries.

EDDY CURRENT TESTING

Eddy current testing is most commonly used to inspect surfaces and tubes. It is an incredibly sensitive testing method, and can identify even very small flaws or cracks in a surface or just beneath it. On surfaces, ETC can be done with both ferromagnetic and non-ferromagnetic materials.

PHASED ARRAY

In a phased array, the power from the transmitter is fed to the radiating elements through devices called phase shifters, controlled by a computer system, which can alter the phase or signal delay electronically, thus steering the beam of radio waves to a different direction.

TIME OF FLIGHT DIFFRACTION

TOFD is usually performed using longitudinal waves as the primary detection method. Ultrasonic sensors are placed on each side of the weld. One sensor sends the ultrasonic beam into the material and the other sensor receives reflected and diffracted ultrasound from anomalies and geometric reflectors.
