This is a Statement of Work (SOW) for the procurement and delivery of one horizontal stainless-steel storage propellant knockout tank with a nominal capacity of approximately 30,000 gallons (±10%). The vendor shall provide all materials, engineering, fabrication, testing, documentation, and delivery for a vessel designed in accordance with ASME Boiler Pressure Vessel Code (BPVC) Section VIII Division 1 (design only). The tank is not required to be code stamped and must be fabricated to applicable standards including AWS D1.6 and ASTM material specifications.

Technical requirements specify a horizontal orientation with a design pressure of 15 psig and minimum fluid temperature capability of –423°F. Materials shall include SA-240 304/304L stainless steel for heads (3/8 inch minimum) and shell (1/4 inch nominal minimum), with SA-182 F304/304L nozzles and stainless-steel saddle supports. Nozzle and opening configurations include one 4-inch nozzle, one 6-inch nozzle, two 18-inch nozzles, and a 24-inch manway with davit, all fitted with Class 150 RFWN flanges. The tank shall include two lift lugs and one tailing lug for handling. Fabrication requires spot radiography, interior and exterior mill finish, and passivated surfaces. Testing shall be performed via hydro/pneumatic testing per ASME BPVC standards and vendor procedures. Vendor drawings must be signed and approved by a NASA engineer prior to manufacturing. The deliverable data package shall include material certificates, test reports, and as-built drawings. Quality assurance requires vendor compliance with QA/QC procedures, use of qualified welders, customer inspection support, and all openings supplied with blinds/covers for shipping. Acceptance criteria include receipt of test reports, material certificates, and drawings, with approved inspection (if applicable).
