Detailed Product Description

ASTM B151 Copper Nickel Pipe CuNi 70/30 Boiler & Condenser Seamless Tube

1.Product Description

Copper nickel pipe is a high-performance alloy tube primarily composed of copper with nickel as the principal alloying element. It is manufactured in accordance with international standards such as ASTM B466/B467, BS 2871, and DNV. The two most common grades are C70600 (90/10) and C71500 (70/30). This material is specifically engineered for demanding environments requiring excellent resistance to seawater corrosion, thermal conductivity, and good mechanical strength.

2.Product Applications

Marine & Shipbuilding: Seawater cooling lines, ballast systems, fire main systems, sanitary piping.
Offshore & Oil & Gas: Hydraulic and lubrication lines on platforms, fire water systems.
Power Generation: Steam turbine condensers, feedwater heaters, air coolers (nuclear & thermal plants).
Desalination: Multi-stage flash (MSF) and reverse osmosis (RO) evaporator tubing.
Chemical Processing: Heat exchangers for acetic acid, brine, and other mild corrosive media.

3.Product Advantages

Superior Seawater Corrosion Resistance: Excellent resistance to pitting, crevice corrosion, and stress corrosion cracking (SCC) in chloride environments.
Anti-Biofouling: Natural resistance to marine organism attachment, reducing maintenance and flow blockage.
High Erosion Resistance: Performs well in high-velocity seawater (3.5 – 4.5 m/s), resisting impingement attack.
Excellent Fabricability: Can be easily bent, expanded, flanged, and welded using standard techniques.
Proven Longevity: Service life of 30+ years in marine applications, offering low life-cycle cost.
Good Thermal Conductivity: Higher than stainless steel, making it ideal for heat transfer equipment.
