Nitrogen Piping Replacement for Plasma Spray Booth

The Air Force Sustainment Center is soliciting quotes for a firm-fixed-price contract to replace and install a 5,000 psi nitrogen gas piping system in Building 3001 at Tinker Air Force Base, Oklahoma. This 100% Small Business Set-Aside project, under NAICS code 811310, requires the demolition of existing unserviceable piping and the installation of a new, leak-free system using 316 Stainless Steel. The scope includes connecting the nitrogen generator, storage cylinders, regulator, and plasma spray booth in accordance with ASME B31.3 standards and government drawing 24E173. All connections must be TIG welded, and the completed system must pass rigorous integrity testing, including a hydrostatic test at 7,500 psi for one hour and a pneumatic test at 5,500 psi for two continuous hours. The government will award the contract to the technically acceptable vendor offering the lowest evaluated price, with a 10 percent price evaluation preference applied for HUBZone small business concerns. Prospective offerors are encouraged to attend the Industry Day and site visit on October 14, 2026, with final responses due by October 16, 2026. Key requirements include strict adherence to OSHA standards for hot work and fall protection, compliance with MIL-STD-130 and MIL-STD-129 for marking and labeling, and the use of the Wide Area WorkFlow system for invoicing. Contractors must provide a list of personnel to the Government Point of Contact within five business days of award and submit all required certifications and insurance proof prior to project closeout.
