About this file
This is a Statement of Work (SOW) for the procurement of high-pressure gaseous hydrogen storage vessels by NASA Langley Research Center for the Direct-Connect Combustion-heated Scramjet Test Facility (DCCSTF).
NASA requires the purchase and delivery of six (6) high-pressure gas storage vessels to replace aging, near end-of-life tube trailers whose recertification costs have become prohibitive. Each tank must be constructed of seamless SA372 Grade J, Class 70 stainless steel and meet ASME UPV Code Section VIII, Division 1 construction requirements with the latest edition and "UIF" stamp. The vessels must be compatible with gaseous hydrogen (GH2), operate within a design temperature range of -20 to 200°F, have a design maximum pressure (MAP) of 2800 psi, and a design working/operating pressure (MAWP) of 2520 psi. Physical dimensions are specified as 24" outer diameter by 0.817" wall thickness by 40' length. All exterior surfaces must be coated with white urethane enamel primer and finish coat, and tanks must be plugged with a blind prior to storage and shipment. Compliance with NASA LPR 1710.40-P2 Section 8 is required for implementation and integration into facility operations.
Each tank shall be integrated into individual stackable bi-directional I-beam framing that maintains safe stress loading throughout transportation and installation. The I-beam framing must support vertical stacking of up to four (4) tanks positioned horizontally in the longitudinal direction and include mechanical mating provisions for adjoining tank/frame assemblies in vertical or horizontal directions. The framing assemblies must incorporate lifting fixtures and eyes to facilitate transport and handling of individual tanks within their respective frames.

Direct-Connect Combustion-heated Scramjet Test Facility (DCCSTF) High-Pressure Gaseous Hydrogen Storage Vessels
SOW - Specifications and Requirements
NASA Langley Research Center desires the purchase, and the delivery of six (6) high-pressure gas storage vessels to accommodate the use of hydrogen in support of test operations at the B1221C Direct-Connect Combustion-heated Scramjet Test Facility (DSCSTF). The additional storage will be used for currently scheduled testing at this facility and will replace existing, near end of life, high-pressure gaseous tube trailers that have been long in service, and who recertification costs have become prohibitive, and restrictive to efficiency of operations. The storage vessels must meet the high-pressure gaseous storage vessel requirements set forth by NASA LPR 1710.40-P2 Section 8 for implementation and integration into their facilities.
Each of the six (6) tanks shall be integrated, conformally seated, and secured in individual stackable bi-directional I-beam framing per specification that follows:
Requirements for the individual tanks are as follows:
1. Be constructed of seamless SA372 Grade J, Class 70 SS
2. Meet code construction requirements per ASME UPV Code Section VIII, IF
3. Compatibility requirement: GH2 (gaseous hydrogen)
4. Design temperature range: -20 to 200 °F
5. Design maximum pressure (MAP): 2800 psi
6. Design working/operating pressure (MAWP): 2520 psi 7.
8.
urethane enamel.
9. Plugged with a blind prior to storage and shipment.
Framing/Stacking/Shipping requirements:
1. Each of the six (6) tanks shall be integrated, conformally seated, and secured by industry practice in individual stackable bi-directional I-beam framing that maintains safe induced stress loading throughout the transportation process from the manufacturer to the facility, and installation.
2. The I-beam framing shall support stacking up to four (4) of the tanks vertically with the tanks positioned horizontally in the longitudinal direction of the tank.
3. The framing shall include provisions to mechanically mate adjoining tank/frame assemblies in either vertical or horizontal directions simultaneously. Additionally, the framing assemblies mating point design shall be inclusive of means of lifting fixtures/eyes that facilitate lift/transport of each individual tank within their respective frames.
