The requirement
- A domestic source for straight-length C12200 tubing, so the customer was not exposed to import lead times.
- Consistent quality across multiple sizes and tempers, hard H85 and soft annealed.
- Full traceability, testing, and documentation, first for qualification and then on every recurring order.
What Ameritube did
- Sourced and released raw hollows against the customer specification.
- Pilgered and drew each part number to size in Hillsboro.
- Annealed the soft part numbers, straightened and finished the rest.
- Eddy current, dimensional, and mechanical testing on every lot, hydrostatic on request.
- Issued MTRs and the PPAP documentation package.
- Packaged and shipped on the customer's monthly schedule.
C12200 melting and casting came in-house in 2025, so new C12200 programs can now start from copper melted in Hillsboro as well.
