Thin Gauge Steel Tubes

I am looking for a reliable way to UT thin gauge, under 5/16", steel tube that has a circumferential joint joined utilizing a backing bar.

I'm not sure I'm properly visualizing what you're doing, but if it's a brazed or welded joint, we may be able to do something with small diameter, sharply focussed immersion transducers and appropriate fixturing. The tube diameter itself is not a problem. If it's just mechanically clamped, on the other hand, it's not a good application for ultrasonic flaw detection.

I'd be happy to look at a drawing if you can send one.

Re: Thin Gauge Steel Tubes
Dear Tom,

Go to www.lixi.com and then to Profiler. This non
contact wall thickness gauge will measure the wall
thickness of thin gauge steel tubes.

Re: Thin Gauge Steel Tubes
We have been inspecting buttwelds in .056"T by 1.0" diameter buttwelds in inconnel tubing with great success using FAST ultrasonics. The backing ring should not be a problem. Not sure that this application is close to what you are doing. If you would like more information please email me.
