Argon Piping Supply, Installation and Testing

The Department of Energy (Fermilab) is issuing a Sources‑Sought notice (Solicitation #04012026) to identify qualified vendors for the “Argon Gas Piping Supply and Installation for LBNF” effort supporting the DUNE experiment. The requirement calls for the supply, underground installation, and testing of a stainless‑steel argon‑gas pipeline that will transport approximately 40,000 metric tons of argon from the surface Ross Shaft Argon Receiving Station to the Central Utility Cavern (CUC) at the 4850 ft level. The pipeline must be fabricated to Schedule 10 stainless steel with the following configuration: 8‑inch diameter from the Argon Receiving Facility to the Ross shaft, 6‑inch diameter from the Ross shaft collar to the 4850 Level, and a return segment of 8‑inch diameter from the Ross shaft to the CUC. Responses are due by 15:00 hours on 30 April 2026. Point of contact is Jerry King (jking@fnal.gov, 217‑390‑1120). The performance location is Lead, South Dakota, United States. Vendors should indicate capability to deliver, install, and certify the specified stainless‑steel piping system in a deep underground environment.
