Technical Report ·
DOI:https://doi.org/10.2172/1031829· OSTI ID:1031829
Reassembly of the inner pressure vessel of a seventeen foot diameter by ten foot long double wall toroidal shaped vessel in which each vessel consists of two concentric cylinders which are capped at each end by an annular dished head. Attached drawing 1, 2, 3, and 4 (all Revision 1) show the repair work items. The work covered by this data report applies only to the inner pressure vessel (See Item 8 remarks) . These work items are: (1) Two circumferential weld seams ( Seams A and G on attached drawing 2) of the north end annular dished head. (2) Two circumferential weld seams (Seam C and F on attached drawing 2) of the south end annular dished head. (3) Rerolling and rewelding of the vertical seam of the 64 3/8 inch nominal inside diameter tube (seam L on attached drawing 2) (4) Welding of the two dust catchers inside the inner pressure vessel (Seams Nand 0 on attached drawing 2). The dust catchers are attachments to pressure parts and were supplied by Fermi National Accelerator Laboratory. (5) Welding of the outer tube of the beam bypass tube (Seams I and K on attached drawing 3).
