Argon Piping Supply, Installation and Testing 04012026
Summary
AI-generated · Apr 02, 2026Supply, install, and test a stainless-steel argon gas piping system to transport argon underground for the Long Baseline Neutrino Facility (LBNF) as part of the DUNE project. About 40,000 metric tons of argon will be moved from the surface to the Central Utility Cavern at the 4850 Level; argon arrives as liquid at the Ross Shaft Argon Receiving station, is stored in tanks, then vaporized and conveyed underground through the piping.
Pipeline routing and sizes: 8-inch Schedule 10 from the Argon Receiving Facility to the Ross Shaft Argon Receiving station; 6-inch Schedule 10 from the Ross shaft collar to the 4850 Level; and 8-inch Schedule 10 from the Ross shaft to the Central Utility Cavern. The work encompasses supply, installation, and testing of this stainless-steel pipeline system as described.
As part of the DUNE experiment, approximately 40,000 metric tons of Argon is required to be transported from the surface to the Central Utility Cavern (CUC) at the 4850 Level. This Argon will arrive at the Ross Shaft Argon Receiving station in liquid form where it will be stored in tanks. It will then be converted to the gaseous phase, where it will be transported underground through a stainless-steel pipeline. This pipeline will be 8 diameter Schedule 10 between the Argon Receiving Facility and the Ross shaft, 6 diameter schedule 10 from Ross shaft collar to the 4850 Level, then return to 8 diameter schedule 10 from the Ross shaft to the CUC. This SOW defined as Argon Gas Piping Supply and Installation for LBNF outlines the requirements for the supply, installation and testing of a stainless-steel pipeline at LBNF as described above
