Hi Katherine,

Could you also revise supply bellows traveler please? It has same issue with heat ring width stating  .500" for width and the part is actually roughly 1.00"

Thanks,
Aaron

Dear all,

Earl, thank you for the detailed inspection information, which was very helpful.

The vendor had a number of difficulties with these parts and requested to make some design changes.  We have unfortunately not updated the JLab drawings in time to feed them back into the traveler, and I have to admit this slipped my mind when you all pulled the return warm-to-cold beampipes for inspection last week.  Please see attached vendor drawings, showing what we have.  The interface points should *not* change, so the dimensions on the inspection traveler are good (other than the width of the heat sink ring, which the vendor increased), but the part does look very different from the drawing.

I have revised the traveler to include the vendor drawings and uploaded to Pansophy.  We can continue to use the current traveler as the dimensions on it are (except one) good until the revision moves through the system.

Sorry for the oversight.

Thanks,
Katherine

Just a heads up.

1)      There is a potential fit up issue with the Return Bellows.  Return Bellows Flange (104210300-A202) has the same features as the Supply Bellows Flange (104210300-A102).  This results in a .899” boss with a diameter of 5.620”.  This does not conform to the drawing and may interfere with build-up.

2)      .06” X 45°= .810.  This is the same feature as the Supply Bellows Flange.

This information is attached to NCR93 with photos.  The drawings appear correct for the Return and Supply bellows.  This seems like a vendor issue.



Please contact me if you have any questions.
