Études et Recherche : Proposition d'une stratégie de contrôle non destructif des tuyauteries par l'extérieur

 

To ensure reliable testing with optimum effienciency, a technique package consisting of Ultrasonic Guided Waves (UGW), Time of Flight Diffraction (TOFD), Phased-Array (PA) and Multi-skip (MS) is proposed. Different tests based on theoretical understanding and numerical simulations of different scenarios were performed to make sure that this package is complete, and can answer all the nondestructive need for testing pipework, especially in nuclear power plant (NPP).

Some numerical results are shown without bring details. For all techniques, a brief description is delivered to allow a non-specialist reader to have a quick background, and how such a technique is suitable for pipes testing in NPPs.

Furthermore, results from experienced feedback of Institut de Soudure, obtained in-situ are presented.

Prospective to use smart welds as guided waves sensors is discussed.
