Our Other Inspection Services

Other inspection techniques are the services we offer to our customers in addition to the 5 basic NDT inspection methods we apply or according to standards, specifications and requests. Your service requests in this direction will be evaluated by our Level-3 or expert staff and we will gladly help you to reach the most accurate result...

Phased Array Ultrasonic Inspection (UT-PA),

A Phased Array system is an ultrasonic probe system consisting of a series of elements (crystals) (eg 16-128) that can be individually excited in a programmed sequence. Thanks to this system, the shape, angle and focal point of the sound beam transmitted into the inspection piece can be controlled electronically. In this way, many different ultrasonic beam profiles can be created using a single probe, and electronic scanning can be performed by dynamically programming the beam orientation.

Phase controlled UT systems can be used in all examination applications where conventional UT technique (Pulse-Echo) is used. The most important advantage over the conventional system is that it makes it possible to catch the reflectors (usually discontinuities) at the most suitable angle by directing the ultrasonic sound beam by using many elements in a single probe assembly.


ToFD, (Diffraction) Ultrasonic Inspection,

Time of Flight Differaction. This ultrasonic inspection technique, unlike the pulse-echo (P-E) technique, is performed by interpreting the diffracted sound waves. The direction of the discontinuity has an importance in this technique. When the sound waves sent into the material hit a discontinuity (eg crack), diffraction waves are formed at the ends of the crack and begin to act as a sound source. These waves are detected and interpreted with the receiving probe. The advantage of this system is that it makes it possible to detect especially planar discontinuities very easily and with high precision.

Shore (Dynamic) Hardness Measurement,

In all metals, especially in steel, hardness can vary within wide limits as a result of cold forming or heat treatment. For this reason, it is a frequently required inspection method. There is no need to prepare a special sample for this test and measurements can be made directly on the material.


Positive Material Idendification (PMI),

Positive material identification (PMI) is used to analyze, verify and identify material grade and alloy composition for quality and assurance control. It is a fast and non-destructive method. With positive material identification, possible product input errors in production can be prevented. Pre- and post-production controls of critical components and resources are carried out in the construction of oil and gas industry, power generation facilities, pharmaceutical and food factories.

With this method, it is possible to verify that the material complies with the desired standard and specification, and to verify that the welded components are made with the correct filling material.

Microstructural Analysis,

Our materials experts are available in the field to determine the life of a component or to determine if the material is properly heat treated, to confirm whether the raw material has been processed to quality standards, or to find out why a material is not responding to certain applications or machining operations, or even to predict and determine the performance of a particular part. It is an inspection method performed on replica samples to be taken or correctly removed samples.


Vacuum Test,

It is a visual inspection method performed with a vacuum pump and a vacuum box prepared in appropriate sizes on the bottom and roof plate welds of atmospheric storage tanks manufactured according to API 650 and similar standards. The importance of the foaming solution used in this test and the cleaning of the test surface are of great importance for the reliability of the test.
