Development and Validation of an Automated Non-Destructive Evaluation (NDE) Approach for Testing Welded Joints in Plastic Pipes/ TESTPEP

Project code: SME-2008-2-243791
ES programme: Framework Programe 7 (FP7)

Project flyer

The objective of the project

Development and validation of automated non-destructive system for testing of welded joints in plastic pipes. The TestPEP project will develop phased array ultrasonic NDE procedures, techniques and equipment for the volumetric examination of welded joints in polyethylene (PE) and other plastics pipes of diameters up to 1m. In addition, the project will develop an automated inspection system that will be able to inspect pipe-to-pipe and pipe-to-fitting butt and socket joints in various plastic pipe materials and diameters between 90 and 1000mm. In parallel, the significance of flaw size and quantity will be established in relation to service requirements. This will be achieved by long-term mechanical testing of joints containing known flaws, and comparison with results for welds containing no flaws.

The technical problem

Being relatively new structural materials, NDE of plastics is challenging, due to high attenuation and low ultrasonic velocity of the material.

Ultrasound institute

Is investigating welds of selected geometry using modeling and experiments and has to determine the parameters of the phased arrays to be used. UI has to investigate and develop the technique for automatic defect detection.
