APPENDIX A

Tube Radiographs

This appendix contains positive prints of the X-ray negatives for each tube sample. Each print contains the date the tube was X-rayed, as well as the name of the tube. The first print gives the X-ray for the first 9 in (markers 0–9) of the tube, and the second print gives the X-ray for the next 3 in, with a 4-in overlap (markers 5–C). See Figures AF1, AF2, AF3, AF4, AF5, AF6, AF7, AF8, AF9, AF10, AF11, AF12, AF13, AF14, AF15, and AF16.
