Brookhaven National Laboratory is seeking quotes for specialty seamless 21-6-9 stainless tubing for the U.S. Department of Energy.
- **Government buyer:** U.S. Department of Energy, Brookhaven National Laboratory (BNL); BNL is managed by Brookhaven Science Associates.
- **OEMs and vendors:** No tubing manufacturer or supplier is identified by name. Brookhaven Science Associates is named as BNL’s managing organization, not as the tubing OEM.
- **Requested product:** 2,500 ft of seamless grade 21-6-9 tubing, UNS S21900, conforming to ASTM A269/A269M-25.
  - Nominal dimensions: 0.313-inch outside diameter and 0.035-inch wall thickness.
  - Supply in 42-ft straight lengths; the Q&A allows a -6/+12 length tolerance and says lengths around 40 ft may be considered. Substantially shorter lengths are not acceptable.
  - Welded or welded-and-drawn tubing is unacceptable. Annealed material is preferred, but cold-worked material will also be considered.
  - Quantity tolerance is ±10%; standard ASTM A269 dimensional tolerances apply.
- **Quality and delivery requirements:** Eddy current testing is required. Delivery documentation must include a certificate of conformance, lot chemical composition analysis, and quality/inspection or dimensional-check information; mill test reports are accepted. Foreign-origin offers are acceptable, and extended mill-run lead times may be considered, with delivery requested as quickly as reasonably possible.
- **Other product line detail:** The Q&A also describes the same tubing but does not state a separate quantity or part number.
