The documents also identify 76MXSG/MXDEJ and OC-ALC/EN; OBCA is identified in the Q&A. - Requirement: Replace and install the Building 3001 plasma spray shop nitrogen piping system, from the generator through the 16-tank storage racks and pressure-reduction equipment to the booth. The scope includes about 300 feet of piping, demolition, tie-ins, supports, fittings, valves, testing, and cleanup. The solicitation lists CLIN 0001 as quantity 1 EA. - Specified OEMs and brands: Swagelok (bleed valve and tube connector), WIKA (pressure gauge), Parker (inline valve), Tescom (dual high-pressure manifold regulator), and Nuvair (twist bleed valves and flexible hoses). No separate installation contractor or reseller is named. - Specified products: Seamless 316 stainless-steel tubing in three sizes; valves, pressure gauge, relief and rupture-disk assemblies, regulator cabinet, flexible hoses, and tube connector. Listed part numbers include SS-BVM8, 232.53, 44-1300 Series, G0505-02, 2KLA2, 527BA-4-CUSTOM, and SS-400-1-4. See product line items for specifications and stated quantities. - Notable technical requirements: Nitrogen flow of 2,500 SLPM; hydrostatic testing to 7,500 psi and leak testing at 5,500 psi. Use ASTM A269 annealed seamless 316L tubing and comply with ASME B31.3 and drawing 24E173. Finished piping must be clean, free of particulates and oils, and 99.9% free of water or moisture. Welding is prohibited in the specialty gas yard. - Scope clarifications: Existing spray-booth valves and regulators are excluded; the inline filter may be reused. Contractor provides labor, materials, equipment, lift, and test-gas source.
