Hoping some one can enlighten me regarding Long range ultrasonic in Stainless steel.
I have spoken to one company they did not seam bothered about it testing 316L, but I spoke to another and I was informed that because of grain structure with in the 316L then the beam would bonce everywhere and not give a true picture.
Which one is right?
Thanks

If it is a casting or something with a lot of welds in it then you wont be able to see very far.
In forged bar you can use longitudinal wave to see a long ways.
Of course the farther you want to look the lower the resolution will be.

I'm looking at doing long range UTS in sch 160 1" and 1.5" 316L Pipe with Welded joints.

2. For those that think it is 'no problem,' ask them to produce a qualification dossier demonstrating that there is an acceptable POD for the imperfections being sought in the same material.

And given that pipe will have a +/-12.5% variation is wall......
If you are looking for 90% wall loss then maybe, you will never find something less than 50%, IMO.
