Request for Information/Sources Sought Notice for 15 ksi Cryogenic Vessel

NASA Stennis Space Center (SSC) is conducting a market‑research Sources‑Sought (RFI 80SSC026K0004) to identify qualified vendors capable of designing, fabricating, testing, and delivering two high‑pressure, vacuum‑jacketed cryogenic vessels for liquid oxygen, liquid hydrogen, and/or liquid methane service. The vessels must be ASME‑code rated (BPVC Section VIII, Divisions I‑III) with a minimum volume of 500 gal (allowable deviation per forge tooling), a maximum allowable working pressure of 15,000 psig, and an operating temperature range of –423 °F to 100 °F. Construction must include vacuum insulation, a diffuser, an anti‑vortex device, and ASME B31.3‑compliant piping. Mechanical interfaces require a bottom‑mounted primary nozzle (6‑in. R‑CON or equivalent) and additional fill, pressurization, and vent nozzles (type R‑CON, locations TBD). Vessels are to be hydrostatically or otherwise proof‑tested at the vendor’s facility, certified per ASME BPVC, and permanently marked with part number, serial number, MAWP, manufacture date, and pressure‑test data. Respondents must submit a capability statement, ASME certifications, in‑house testing capability, ROM cost and schedule, and any clarification requests, along with up to three similar‑project examples (max 10 pages, .docx or .pdf). Required data elements include legal name, address, UEI, SBA small‑business designations, and recommendations on NAICS code, typical project duration, and warranty inclusion. All responses are voluntary, will not be compensated, and will not be returned; they are for information only. Submissions are due by 13:00 CST on 24 April 2026 to Stephen Penton (stephen.d.penton@nasa.gov). NASA Clause 1852.215‑84 (Ombudsman) applies.
