ASTM B111 C70600 Cu90%Ni10% Copper Nickel Seamless Tubes For Electric Power Plant​

Chemical Composition (%) max

Mechanical Properties

Seawater resistance (critical in coastal power plants)
Erosion-corrosion resistance (high-velocity water flow)
Long-term reliability (reducing downtime and replacement costs)

Properties (90-10 Cupronickel)

Thermal Conductivity: Efficient heat transfer for condensers.
Mechanical Strength: Good durability under high-pressure conditions.

Biofouling Resistance: Inhibits marine growth, reducing maintenance needs.

Corrosion Resistance: Excellent resistance to seawater, brackish water, and steam, making it ideal for cooling systems.

Key Applications in Power Plants

Condensers
Used in steam condensers to convert exhaust steam back into water after passing through turbines.
C70600’s corrosion resistance ensures long service life in aggressive cooling water (seawater or freshwater).

Heat Exchangers
Facilitates heat transfer between fluids (e.g., cooling turbine exhaust or other processes).

Cooling Water Systems
Used in pipes and tubing for circulating cooling water (especially in coastal/nuclear plants where seawater is used.

In a word, ASTM B111 C70600 tubes are essential in power plants for efficient heat exchange, corrosion resistance, and longevity, especially in condensers and cooling systems exposed to seawater or harsh conditions. Their use helps maintain plant efficiency, reduces maintenance costs, and extends equipment lifespan.
