USA Piping Solution supplies Copper Nickel condenser and heat exchanger tube to ASTM B111, UNS C71500, the American standard covering this alloy in seamless condenser tube form. C71500 is the 70/30 copper-nickel composition long used in power plant condensers, marine heat exchangers, and desalination equipment for its resistance to high-velocity, high-chloride seawater. Every tube ships mill certified and traceable to heat, temper, and test report. If your specification is written to the British Standard instead, see our BS 2871 Part 3 CN107 Copper Nickel Condenser Tube page, the same alloy under its UK designation.

For general engineering pipe in this alloy, including welded construction to ASTM B467, see the full Copper Nickel 70/30 Pipes & Tubes page. The 90/10 grade follows the same standard structure under UNS C70600; see Copper Nickel 90/10 Pipes & Tubes if that is the grade your project needs.
Applications
- Power Plant Condensers: main condenser tube bundles in fossil and nuclear power generation.
- Marine Heat Exchangers: condensers and coolers on vessels operating in high-velocity or highly saline seawater.
- Desalination Plants: evaporator and heat-recovery tube bundles in MSF/MED systems.
- Offshore Platforms: cooling water heat exchangers where 70/30's added nickel over 90/10 is worth the cost.

Frequently Asked Questions
What's the difference between this page and your BS 2871 Part 3 CN107 page?
No difference in the alloy, CuNi30Mn1Fe, 70% copper and 30% nickel; the difference is which standard your project specifies. This page covers the US designation, ASTM B111 and UNS C71500. Our BS 2871 Part 3 CN107 page covers the same tube under the UK designation. Tell us which one your drawing calls for and we'll certify accordingly.
Can you supply this tube with an ASME SB111 certificate for code work?
Yes, ASME SB111 is the boiler and pressure vessel code equivalent of ASTM B111 and covers the same material.
What sizes are available in C71500 condenser tube?
Send us your OD and wall thickness and we'll confirm current mill availability and lead time against your specification.
