C71500 Copper Nickel Size & Price PDF
What is a C71500 copper nickel tube?
Standards: ASTM B111/ASME SB111, ASTM B251, BS EN1057
Size range: Outer diameter 2.0 to 406 mm, wall thickness 0.3 to 50 mm, length 18 meters or custom orders.
Inspection: 100% eddy current testing, 100% hydrostatic testing.
Supply in straight pipe or U-bend form.
We also supply copper alloy components for heat exchanger applications, such as finned tubes, tube sheets, EEMU 146 fittings, and EEMU 145 flanges.
Copper-nickel alloy 70-30 tubes (C71500) typically offer the best impact corrosion resistance of all copper alloys and are resistant to most acids and water corrosion. They are suitable for harsh corrosive environments where a longer service life is required compared to other copper alloys.
Key Features of C71500 Copper
Superior Corrosion Resistance: Exceptional resistance to seawater corrosion, especially under high-pressure environments.
Excellent Thermal Stability: Performs well under high temperatures without degradation.
Anti-Biofouling Properties: Naturally resists the build-up of marine organisms.
Ease of Fabrication and Weldability: Suitable for various fabrication processes.
Extended Durability: Excellent choice for harsh marine and industrial environments.
