Seamless 21-6-9 Tubing
ENERGY, DEPARTMENT OF.ENERGY, DEPARTMENT OF.BROOKHAVEN NATL LAB -DOE CONTRACTOR · Response deadline: Tue, 10 Nov 2026
What the government is buying
The Department of Energy's Brookhaven National Laboratory needs seamless 21-6-9 tubing. This is a combined synopsis/solicitation, meaning the notice serves as both an announcement of planned procurement and the formal solicitation document that contractors can respond to directly.
Seamless tubing refers to metal tubing manufactured without a welded seam, typically produced through extrusion or rotary piercing processes. The "21-6-9" designation describes a nitronic stainless steel alloy—21% chromium, 6% nickel, 9% manganese—known for its high strength, excellent corrosion resistance, and good cryogenic properties. This material is commonly used in demanding environments such as particle accelerators, nuclear research facilities, and other scientific applications requiring reliable performance under stress. Brookhaven National Laboratory operates major research facilities including the Relativistic Heavy Ion Collider, which may drive specialized material requirements.

Who can bid
This procurement is open to all responsible sources—there is no small business set-aside, so large businesses may compete alongside small businesses. The NAICS code 331210 corresponds to "Iron and Steel Pipe and Tube Manufacturing from Purchased Steel," which covers establishments that manufacture welded, riveted, or seamless pipe and tube from purchased iron or steel. Small business size standards for this NAICS can be found in SBA regulations; see the solicitation to confirm whether the contracting officer has established any size standard for this specific acquisition.
Given the specialized nature of 21-6-9 alloy tubing, potential bidders likely need capabilities in custom seamless stainless steel production, material certification, and precision manufacturing for research or nuclear-grade applications. Firms with experience supplying DOE national laboratories or similar federally funded research facilities may have relevant past performance.
How to put together a competitive bid
For seamless specialty alloy tubing, focus your proposal on demonstrating exact material compliance and quality assurance. The government will likely require detailed material certifications showing the 21-6-9 composition matches specifications, heat treatment records, and dimensional tolerances. See the solicitation for exact technical requirements.
Key elements to address:
- Material traceability: Provide mill test reports and documentation establishing full chemical and mechanical property certification back to the raw material source
- Manufacturing standards: Reference applicable ASTM, ASME, or DOE-specific standards for seamless tubing; specify your quality systems and any relevant certifications (ISO 9001, AS9100, or nuclear quality programs if applicable)
- Testing and inspection: Detail ultrasonic testing, eddy current inspection, hydrostatic testing, or other nondestructive evaluation methods you employ
- Past performance: Highlight deliveries to national laboratories, aerospace, nuclear, or other high-reliability customers requiring similar alloys
- Delivery and packaging: Address protection against contamination and damage during shipment, particularly important for precision tubing destined for sensitive research equipment
Since this is a combined synopsis/solicitation, your response format and evaluation criteria should be specified directly in the posted document. Review these carefully to ensure complete compliance.
