Place of performance is NASA Glenn Research Center in Cleveland, Ohio, with packaging and transport from the vendor to that location. The vendor must design and fabricate vacuum-jacketed piping and components to ASME B31.12 standards with LH2-compatible materials, procure cryogenic globe valves rated for −423°F with a minimum flow coefficient of Cv=8.3, and provide positioner transmitters with 4–20mA signals meeting NEC Class I, Division 2, Group B specifications. System design pressure is 275 psig. All components must be cleaned for oxygen and cryogenic service.

Testing requirements include hydrostatic testing at 1.5× design pressure (or pneumatic at 1.1× for a minimum 10 minutes), vacuum retention testing for at least 7 days, leak testing at 1×10⁻⁸ CC/s, cold shock testing using liquid hydrogen, and radiography of 10% of total welds on fluid process piping. Deliverables include certificates of conformance, approved drawings, inspection reports, material certifications, comprehensive testing reports, and the completed assembly. The vendor must demonstrate prior successful completion of similar projects and obtain NASA facility engineer approval before work begins.

Quotes must include CAGE Code, UEI number, requested delivery lead time, shipping costs (if applicable), and discounts. Payment terms are Net 30 FOB Destination; credit card payment is not accepted. Award will be made to the responsible offeror submitting the lowest price technically acceptable offer. NAICS code is 332996; PSC is 4730.
