U-bend and lo-finned tubes are stocked and available for immediate shipment from our Brooklyn, NY facility. For specialized marine and offshore requirements, we supply copper nickel pipe to SB 466, SB 467, and SB 36.19 specifications, along with bars to SB 151 and MIL C 15726 standards.

Admiralty Brass Tubes & Pipes

Applications and specifications

Our admiralty brass tubing is sourced from ISO-certified producers and supplied to ASTM B111 and ASME specifications. It is widely used in surface condensers, heat exchangers, and salt water cooling circuits where moderate corrosion resistance and cost efficiency are priorities. Available in seamless drawn form with tight OD and wall thickness tolerances for tube sheet applications.

Frequently Asked Questions

What is the difference between C70600 and C71500 cupro nickel?

C70600 (90/10) contains 10% nickel and offers excellent corrosion resistance with good formability — ideal for marine and seawater applications. C71500 (70/30) contains 30% nickel, providing higher strength and better performance at elevated temperatures, making it the preferred grade for power plant condensers and high-pressure systems.

Do you supply cupro nickel tubes to ASTM and ASME specifications?

Yes. Dexter Sales supplies copper nickel tubing to ASTM B111, ASME SB 466, SB 467, and related specifications. Military-grade material to MIL C 15726 is also available. Contact us to confirm availability for your specific specification and size requirement.

Are U-bend and lo-finned tubes available in cupro nickel?

Yes. U-bend and lo-finned tubes are available in cupro nickel, admiralty brass, and standard copper alloys. These forms are commonly specified for shell and tube heat exchanger applications where thermal efficiency and compact design are priorities.

What industries do you serve?
