PIP-II CM 2K Pressure Safety Device - Rupture Disks

The Fermi National Accelerator Laboratory is soliciting proposals for the design, manufacture, testing, certification, and delivery of cryogenic rupture‑disk safety devices (CM 2K) and associated burst‑alert sensors for the PIP‑II accelerator project. The devices must be ASME‑U‑stamped, constructed of Inconel for the rupture disk and 316 SS for the cartridge, meet stringent helium leak‑rate criteria, and be supplied with full certification and documentation. The contract will be a firm‑fixed‑price award evaluated on lowest‑price‑technically‑acceptable basis. • Scope: supply 33 cryogenic rupture‑disk assemblies (30 high‑set, 3 low‑set) plus burst‑alert sensors, fully tested and certified per Specification ED0049129. • Technical requirements: ASME Section VIII U‑stamp, Inconel disks, 316 SS cartridges, ≤10⁻⁸ atm‑cc/sec leak rate, 4‑inch ASME B16.5 flange interface, DAP delivery to Batavia, IL. • Procurement: Firm‑fixed‑price, LPTA evaluation, submission via RFP 387878‑DSF, deadline October 30, 2026 2 PM CT, contact Seth Fryar for questions.
