General Description

NASA SSC is seeking information from qualified vendors capable of designing and fabricating a high-pressure, vacuum-jacketed cryogenic vessel suitable for liquid oxygen, Liquid Hydrogen and/or Liquid Methane service. A quantity of two will be required.

Intended Fluids

Liquid Oxygen, Liquid Methane, Liquid Hydrogen.

Requirements

Maximum Allowable Working Pressure (MAWP): 15,000 psig. Minimum Volume: 500 gallons, volume can deviate based on readily available forge tooling. Operating Temperature: Minimum -423°F, Maximum 100°F.

Vessel Construction Requirements

ASME Code rated vacuum jacketed vessel required. Must meet ASME BPVC Section VIII Divisions I, II, or III, piping to conform to ASME B31.3. Vessel shall include vacuum insulation, diffuser, and anti-vortex device.

Mechanical Interface Requirements

Main nozzle located on bottom. Primary nozzle connection: 6-inch R-CON or equivalent with justification. Fill nozzle, pressurization nozzle, vent nozzle, location TBD, type R-Con.

Testing & Certification

Testing shall conform to ASME BPVC.  Hydrostatic or required proof testing at vendor facility.

Marking Requirements

Vessel must be permanently marked with manufacturer part number, serial number, MAWP, date of manufacture, and pressure test information.

RFI Response Expectations

Vendors should provide a capability statement, similar past project experience, ASME certifications, in-house testing capability, ROM cost and schedule, and any exceptions requiring clarification.

RESPONSE INSTRUCTIONS:

Respondents to this RFI are to provide the following:

The legal Name and full Address of your Company. Your Company's Unique Entity Identifier (UEI). A detailed description of your company's interest in, and demonstrated ability to perform, the requirements specified within the requirement specified in this notice. All relevant small business designations as certified by the Small Business Administration (SBA). Provide examples of up to three (3) past projects of similar size and complexity.

Responses should be formatted as either MS Word (.docx) or Adobe Portable Document Format (.pdf) and should be limited to a maximum of ten pages.

Proprietary/competition sensitive information (appropriately marked) will be protected from disclosure to the greatest extent practical; however, it is preferred that respondents do not provide proprietary or otherwise restricted responses. No faxes, courier delivered, or telephone inquiries/submissions will be accepted.

QUESTIONS FOR INDUSTRY:

The Government requires that interested vendors responding to this RFI, provide their answers, experience, and recommendations on the following questions related to providing a 15 ksi Cryogenic Vessel:

What NAICS code do you recommend for this requirement. (ie. 332311, 332420, 333914, 423830, 423510, or other) What is your average project duration (from contract award to delivery, and installation)? Is a one-year warranty included in the total price for a cryogenic vessel, or is that a separate cost? Provide any additional recommendations that would help the marketplace propose/quote this requirement. Would you consider this as COTS?

CONTACT INFORMATION & SUBMISSION:

All questions related to this Request for Information (RFI) should be directed to Stephen Penton at stephen.d.penton@nasa.gov by the close of this RFI April 24, 2026 1:00 P.M. CST
