EDDY

AUTOMATED NONDESTRUCTIVE EXAMINATION CONCEPT FOR HEAT EXCHANGER TUBES USING THE EDDY CURRENT METHOD WITH A SENSOR MADE FROM NANOSTRUCTURATED MATERIAL 

Program:  Research for Excellency

Project manager: Dr. Nicolae Farbas

Project start: 15.09.2006                           Project end: 15.10.2008

Partners:

  • ISIM Timisoara – project coordinator

  • IFT Iasi

  • ICPCE-CA Bucuresti

  • RAAN SCN Pitesti

The project’s aim is to develop the theoretical and practical knowledge in using the eddy current method by nondestructive examination of steel pipe’s inner side. A new type of sensor has to be developed based on nanostructure amorphous materials for the detection of surface and subsurface defects disturbing the field of induced eddy currents. The principle of the method is extendable on other materials too, the examination in the field of aeronautics where light materials (aluminum, titanium etc) are frequently used.

Based on the new sensor in the project a computer-aided instrument’s prototype has to be developed in order to perform the automated defect examination of pipes in chemical and energetic industry.

In spite of the fact that this instrument is dedicated to a sectoral application, it can be adapted for other sector like the nuclear.

The research has a complex and a excellency character because the research performing and the prototype’s development needs specialist coming from physics, electronics, hardware, software, fine mechanics, nondestructive examination, product design and so on, all of them having high professional skills.

The project will be performed into the frame of a partnership between ISIM Timisoara specialized in material testing, including nondestructive testing, IFT Iasi specialized in eddy current techniques, nanomaterials and sensors, ICPE-CA Bucharest having experience in industrial electronics and software and SCN Pitesti specialized in nuclear physics research.

Results of project in progress:

  • Design of the mechanical part of the equipment

Automate nondestructive examination system of heat exchanger tubes

 

  • Design of the eddy current sensor

  • Design of the control system
