I am interested in finding any articles or reports on the ultrasonic testing of butt fused welds in polyethylene pipe. I have seen some relevant information at http://www.ndt.net, however I was wondering if there are any other articles available.
Thank you

Jeff

• METHOD AND APPARATUS FOR TESTING WELDS IN PLASTIC PIPE - US PATENT 4,610,166
• A search of the GRI database at http://www.gri.org using butt fusion gives several references.
• The bible of ultrasonics, Krautkramers "Ultrasonic Testing of Materials" 4th edition, page 557 gives reference to IIW-V-627-78 although I do not know the current status of this document. (Does the German 5th Edition, give anymore?)
• The most recent reference I have come across is from GRI "Proceedings - 1997 International Symposium - Plastic Piping Systems for Gas Distribution - Session 6 - Ultrasonic Evaluation of Butt Fusion Welded Polyethylene Pipes" October 20 -23, 1997
