E-MAIL: Sue DePew, sue.depew@msfc.nasa.gov. THIS NOTICE CONSTITUTES AMENDMENT NO. 01 TO THE COMBINED SYNOPSIS/RFQ FOR Cylindrical Vacuum Chambes. Companies shall acknowledge all amendment(s) in their quote. This notice serves as the official amendment to subject synopsis/RFQ and a written amendment will not be issued. The purpose of this amendment is to provide clarification of questions/issues with the specifications as follows: Small Chamber: The 6 foot length refers to the length of the cylindrical portion of the chamber. When you add on the length of the domed end caps the total length of the vessel increases to 8 feet. Each half section of the chamber includes a 3 foot cylindrical part and a 1 foot radius domed access door part. The 2 half sections should fit together at the end opposite the domed access door to form a complete chamber 8 feet long. One of the half sections has (12) 4" flanges mounted in 4 sets of (3) along the length. Each set of (3) flanges is offset 90 degrees circumferentially around the half chamber. There is an additional 4" flange on the end cap. There are thus (13) 4" flanges on this half section of vacuum chamber. The other half section has (11) 4" flanges and (1) 6" flange mounted in 4 sets of (3) along the length. Each set of (3) flanges is offset 90 degrees circumferentially around the half chamber. There is an additional 4" flange on the end cap. There are thus (12) 4" flanges and (1) 6" flange on this half section of vacuum chamber. Large Chamber: In port descriptions: "90 flange" refers to polar angle -- 90 flange -- bolted 10" OD, 7.81" bore. Graining will be acceptable. The due date for receipt of offers is extended to July 31, 1998.
