Ultrasonic Testing System, Immersion Tank

I am interested in inspecting 1/4" to 1" OD stainles steel tube, 100% UT, 4 - 5 channels. I am looking for a system able to inspect 2 opposite axial directions, 2 opposite circumferential directions and maybe, one channel for dimentional inspection. Thanks. SJ

Re: Ultrasonic Testing System, Immersion Tank
Are you sure about this?

1/4 diameter Stainless tube would presumably be very thin walled. It seems unlikely that a UT inspection would be the most effective approach.

Re: Ultrasonic Testing System, Immersion Tank
I guess that these tubes are nuclear fuel cladding tubes. I remember my time in Krautkramer for 20 Years ago we delivered ultrasonic systems for this application. The tube wall thickness range of 0.4 to 0.9 mm and OD 4.5 to 15mm of length of 5 - 6 meters. "Advanced Nuclear Fuels GmbH" located in Lingen Germany used a system. Today UT companies like GE Inspection or intelligeNDT Systems & Services will know more about this application.

Here is an article presented at the WCNDT2000 which describes this application:

Re: Ultrasonic Testing System, Immersion Tank
TAC Technical Instrument Co. in New Jersey has made systems for this application for years. Have a look at tactictest.com. I have no relationship with the company other than as a satisfied user of their equipment for mmore than 25 years.

Re: Ultrasonic Testing System, Immersion Tank
Rolf is right. Such thin walled tubing are normally used in nuclear fuel cladding and in case of stainless steel tubes, are meant for Fast Reactors, TACTIC and ROTA (Nukem) and now EEC (India) are in a position to supply such systems. There could be others too.

I would recommend a system which integrates UT, ET and Laser based dimensional / visual inspection so that the time of inspection comes down and reliability increases. ET is essential in addition to UT to ensure that pin-hole type discontinuities are detected. Alternatively, 100% hydrostatic test is needed.

I will be able to discuss more details if needed.

Magnetic Analysis Corp. has supplied supplied several rotating head ultrasound systems for testing stainless steel tubing to customers in the USA. We have a system that will test down to 1/4'' with 7 transducers.
