# Copper-nickel for ships, from a US mill.

Ameritube has supplied copper-nickel pipe and tube to the US Navy, the Defense Logistics Agency, foreign navies under FMF, and commercial shipyards for fifteen years. Pipe and tube are pilgered, drawn, annealed, and tested in Hillsboro from qualified cast shells, with origin documented on every certificate.

TP316 / 316LStainless Steel

## What we supply for shipboard seawater systems

- **Copper-nickel pipe** in C70600 (90/10) and C71500 (70/30) to MIL-T-16420K, MIL-T-24107, ASTM B466, and ASTM B467. Sizes 1/4" through 2" NPS manufactured in Hillsboro; 2-1/2" through 24" distributed from audited, qualified mills and certified through our own lab.
- **Copper-nickel tube** for condensers, coolers, and heat exchangers to MIL-T-15005F and ASME SB-111, including U-bends.
- **Sleeves and couplings** manufactured in-house for brazed and welded joints.
- **Butt-weld fittings**: elbows, tees, reducers, caps, and stub ends in 90/10 and 70/30 per MIL-F-1183 and ASME B16.9 patterns. See the fittings catalog.
- **Flanges**: composite, slip-on, and weld-neck flanges per MIL-F-20042 and commercial standards. See the flange catalog.
- **Monel 400 and Alloy 625** tube and bar for pump, valve, and instrumentation components.

## Why shipyards and the Navy buy from Ameritube

**Processed and documented in the USA.** DFARS 252.225-7009 and Buy American clauses ask where the alloy was melted as well as where it was finished. Ameritube states both on every certification: shell origin, and the pilgering, drawing, annealing, and testing done in Hillsboro, Texas. C12200 is melted and cast in-house today; copper-nickel melting is planned.

**We know the specifications.** MIL-T-16420K has five pressure classes, its own hydrostatic and ultrasonic requirements, and marking and packaging rules that trip up commercial mills. We have shipped to it for fifteen years, including complete ship sets to a foreign navy under the FMF program with valves, fittings, and flanges included.

**One package, one certification set.** Pipe, fittings, flanges, and tube on one order, with matching MTRs, certificates of conformance, and DFARS statements. Fewer suppliers for the buyer to manage and fewer gaps for the inspector to find.

**Testing in-house.** Hydrostatic, ultrasonic, eddy current, and air-under-water testing on site, with Level II certified NDT operators.

## Standards

MIL-T-16420K, MIL-T-24107B, MIL-T-15005F, MIL-F-1183, MIL-F-20042, ASTM B111, B466, B467, ASME SB-111, SB-466, SB-467, and NAVSEA drawings on request.

**What to include in your RFQ**Alloy (C70600 or C71500), pipe or tube, NPS and class (MIL-T-16420K Class 200, 700, 1650, 3300, or 6000) or OD and wall, length, quantity, the fittings and flanges needed, DFARS or Buy American requirement, and the level of inspection and certification the contract calls for.
