ASTM B111 C68700 Heat Exchanger SMLS Tube , for Heat Transfer

C68700 seamless tubes are high-quality, corrosion-resistant tubes made from aluminum brass, which is a copper alloy combining copper, aluminum, and zinc as its primary components. This material is widely known for its excellent corrosion resistance, particularly in marine and industrial environments where seawater or other aggressive media are present.

Key Features of C68700 Seamless Tubes:

1. Corrosion Resistance:
C68700 is highly resistant to corrosion caused by seawater, brackish water, and other types of saline environments, making it ideal for marine applications and heat exchangers.

2. Durability:
The addition of aluminum in the alloy enhances its strength and makes it more durable under high-stress conditions.

3. Seamless Construction:
These tubes are manufactured without any welded joints, which ensures uniform strength and eliminates the risk of weak points, improving reliability under pressure.

4. Thermal Conductivity:
The copper content provides excellent thermal conductivity, making the tubes suitable for heat transfer applications like condensers and evaporators.

5. Anti-Fouling Properties:
The alloy's surface resists biofouling (the accumulation of microorganisms or plant life), reducing maintenance costs in marine environments.

Chemical Composition:

Mechanical Properties:

Common Applications:

· Heat Exchangers: Used in power plants, chemical industries, and desalination plants.

· Marine Applications: Ideal for shipbuilding, cooling systems, and other seawater-related systems.

· Condensers and Evaporators: Applied in HVAC systems and industrial cooling systems.

· Desalination Plants: For transferring seawater in salinity reduction processes.
