Precision Vacuum-Grade Stainless Steel Tubing Fabrication

Fifteen-nine units of custom-length 316L stainless steel tubing must be fabricated to the exact specifications of drawing PF-444-161-25 Rev.01, with each unit requiring precision cutting, welding where necessary, surface finishing, thorough cleaning, and rigorous inspection to meet vacuum-grade standards suitable for deployment in a particle accelerator environment. The work demands high-purity material handling and process controls to ensure absence of contaminants and structural integrity under extreme vacuum conditions, with all deliverables conforming to industry-specific requirements for scientific instrumentation. This subcontract opportunity, posted by SLAC National Accelerator Laboratory under the U.S. Department of Energy, is for work to be performed in Menlo Park, California, with a response deadline just one day after posting on June 26, 2026, indicating an urgent procurement timeline. The North American Industry Classification System code 332211 confirms the focus on pipe and tube fitting manufacturing, and all fabrication must align with vacuum-grade technical expectations, including surface finishes that minimize outgassing and dimensional tolerances critical to accelerator performance. The tight submission window and specialized nature of the work require experienced contractors with proven capabilities in high-purity metal fabrication for scientific applications.
