phased-array technologies


TestPEP is a European project started in February 2010, aiming to develop an automated solution for the inspection of welded joints in plastic pipes. This 36-month project is part of the European Union 7th framework program. It involves 15 organizations from seven countries, including M2M from France.


Plastic pipes offer significant advantages over other materials such as cast iron, steel, copper and concrete, for the transportation of fluids (natural gas, water, effluent and corrosive liquids). However, as plastic materials show specific physical properties bringing high attenuation and low ultrasonic velocity, TestPEP faces several technical challenges. Previous projects have brought knowledge about the current welding techniques (butt fusion and electrofusion). The market now needs a complete inspection solution of plastic pipes integrating data analysis.

In this context, the main objective of TestPEP is to develop ultrasonic phased-array equipment, techniques and procedures for the non-destructive evaluation (NDE) of welded joints in plastic pipes. The automated system will be used for volumetric examination of pipe-to-pipe and pipe-to-fitting welds, butt and socket joints, for pipes up to 1m diameter.
