Products Description
SB171 C71500 Copper Alloy Pipe
Advantages of SB171 C71500 Copper Alloy Pipe
- C71500 contains 30% nickel, which makes SB171 C71500 Copper Alloy Pipe have excellent seawater corrosion resistance and is suitable for use in ships, offshore applications, and desalination systems.
- Its non-magnetic advantage makes it ideal for MRI rooms and medical equipment, as well as instrument systems with magnetic interference problems.
- C71500 is stronger than C70600 and is suitable for high-pressure and structural applications.
Applications of SB171 C71500 Copper Alloy Pipe
- Marine industry: seawater piping systems, ship hulls and condenser tubes
- Power generation: heat exchanger and condenser tubes, cooling water systems
- Chemical processing: acid and brine pipelines, corrosive media handling
- Offshore and oil platforms: fire water systems
