This is a Technical Ordering Data (TOD) attachment for a federal contract (N3904025P0138, Item 0001) specifying the manufacture and delivery of copper-nickel composition tubing.

The contract requires the production of seamless, annealed copper-nickel tubing (70/30 composition) per MIL-T-16420K specifications, with a National Stock Number of 1H 4710-00-455-0193 X2 and part number MILT16420K,0.3750D. The material must meet Class 3300 specifications with an outside diameter of 0.375 inches and minimum wall thickness of 0.049 inches. Manufacturing must comply with MIL-T-16420 with modifications including specific composition (70/30 copper alloy, annealed temper, seamless grade 2), hydrostatic testing for ultrasonically tested tubes, and detailed weight specifications for various tube sizes ranging from 0.250 inches to 3.500 inches nominal outer diameter. Each finished tube requires 100% ultrasonic examination per NAVSEA T9074-AS-GIB-010/271 (Revision 1 of 9/11/2014) to verify wall thickness compliance. The contract mandates material certification, procedure approvals for ultrasonic testing, cleanliness requirements per Section 3.2 of the IRPOD and MIL-T-16420K, and permanent material marking on each piece including material designator "CNA," manufacturer identification, vendor traceability number, and specification-required information. Preservation and packaging must follow ASTM D3951 standards with material shipped in wooden boxes with metal strapping for six-inch OD and larger pipe/tube. Government inspection is required during manufacture and prior to shipment, with all non-conformances requiring procuring activity waiver approval. The contract incorporates quality requirements per FAR 52.246-11 supplemented by NAVSEA calibration and quality management system requirements.
