E-MAIL: Cynthia W. Dea, C.W.DEA@larc.nasa.gov. This notice is a combined synopsis/solicitation for commercial items prepared in accordance with the format in FAR Subpart 12.6, as supplemented with additional information included in this notice. This announcement constitutes the only solicitation; quotes are being requested and a written solicitation will not be issued. This procurement is being conducted under the Simplified Acquisition Procedures (SAP). Liquid Nitrogen Dewar -- 1 each, in accordance with the following specifications: The following are procurement specifications for a Cryogenic Liquid Storage System, which shall hereinafter be referred to as "Tank", consisting of an inner vessel, outer vessel and ancillary equipment to facilitate the storage, and distribution, of liquid nitrogen. 1. Tank capacity rating: 1580 gallons (gross), 1491 gallons (nominal), Liquid Nitrogen. 2. Maximum Allowable Working Pressure rating: 250 psig. 3. Normal Evaporation Rate no greater than: 0.33% (rate %/day O2). The vendor shall submit seven (7) copies, within fifteen (15) calendar days, after receipt of order, detailed calculations and actual test results for storage vessels of the type, as specified herein, which would clearly indicate that the aforementioned Normal Evaporation Rate would be achieved. 4. Maximum outside diameter: 70 inches. 5. Maximum total height: 200 inches. 6. Tank shall be designed, fabricated, tested and stamped in accordance with Section VIII, Division I of the ASME Code. 7. Inner vessel shall be constructed of a 300 series stainless steel. 8. Outer vessel shall be constructed of carbon steel. 9. Tank shall be equipped with a back pressure regulator valve to control pressure. The valve shall have a set range from 0-250 psig minimum. 10. Tank shall come complete with automatic pressure building and control circuit. 11. Inner vessel shall be equipped with dual relief valve and rupture disc (mounted in a threaded union type holder) protection. Relief valve/rupture disc shall be provided with threaded outlets. A 3-way diverter valve shall be provided to allow for in-service maintenance access to either relief valve and rupture disc pair. The diverter valve shall be designed to prevent blocked flow during crossover. Additionally, the inner vessel shall be equipped with two (2) relief valves set at 70 psig and with the capability to handle pressure rise due to heat leak. Each relief valve shall be located in the respective crossover circuit. 12. Outer vessel shall be equipped with over-pressurization protection. 13. Tank shall come complete with six (6) sets of spare rupture disc(s) and associated O-rings and/or seals for the inner vessel and the outer vessel. These disc(s) shall be clearly marked as to set point and location of use and shall be individually packaged. 14. Outer vessel shall be equipped with a thermocouple (vacuum) gauge with isolation valve. 15. Inner vessel shall be equipped with a pressure gauge (minimum face diameter of 4", stainless steel housing, weather proof) with a 0-500 psig dial full scale. 16. Tank shall be equippedwith a liquid level gauge calibrated to read vessel volume in gallons, liquid nitrogen. 17. Outer vessel shall be primed and painted white. Paint shall be weather resistant. 18. Tank shall be equipped with a 1-1/2 inch tube socket fill connection compatible with a 1-1/2 inch copper tube (Type K) extension. CGA adapter shall be shipped, loose, with tank. 19. Tank fill line shall be equipped with a check valve to prevent back flow from tank. 20. All vents shall be equipped with check valves to prevent backflow into tank. 21. Lifting lugs shall be provided. 22. Tank shall be equipped with an auxiliary liquid withdrawal connection. 23. Tank shall be equipped with an auxiliary gas withdrawal connection. 24. Tank shall be equipped with both top fill and bottom fill capability, with the necessary valving to facilitate either fill mode. In addition, a full trycock valve shall be provided. 25. Isolation valves shall be supplied at all withdrawal locations. 26. The tank shall be equipped with the necessary line reliefto protect where liquid may become trapped. 27. The tank shall be equipped with an economizer circuit. 28. The tank shall be supplied pressurized with 20 psi pure nitrogen gas, at ambient temperature, to prevent contamination of the inner vessel with air. 29. The tank shall be equipped with a pressure line strainer to protect the pressure regulating equipment. 30. The tank shall be equipped with two (2) 1/4 inch gas sample valves. 31. The vendor shall manifold together all discharges to two (2) common headers as follows: Relief valve and rupture disc discharge outlets shall be routed to one common header. Drains and all other normal vents to another common header. The headers shall be located on the underside, above ground level and designed to handle worst case flow conditions, without overpressurization of the tank and ancillary piping. The manifold discharge end connections shall be threaded for connection to the customer's vent piping system. 32. Notwithstanding the foregoing, the tank shall be equipped with all other appurtenances to facilitate the industry standard practice for the storage, and distribution, of liquid and gaseous Nitrogen. Furthermore, all exterior surfaces shall be protected from rusting as a result of exposure to outside weather conditions. 33. The tank shall be supplied completely assembled, such that, upon receipt, it can be put into immediate operation 34. Ancillary piping shall be designed, fabricated, installed, and tested per the requirements of ASME B31.3. 35. Vendor shall submit ten (10) copies of the following within fifteen (15) calendar days of receipt of order: a) Installation, Assembly, Schematic Drawings b) Operation Manuals c) Vendor Technical Data For All Tank Equipment Note: Data shall include vendor part numbers, technical data depicting, as applicable, component materials, flow characteristics, pressure ratings, temperature ratings, heat transfer characteristics, operating characteristics, operating instructions and maintenance procedures. d) Installation and Rigging Instructions (including foundation loading and skid bolt pattern) 36. Registration: National Board 37. The tank shall be designed and fabricated such that it can be stored horizontally without any resulting damage.
