1. What is the ASTM grade of C70600 Copper Nickel Flange?
ASTM Standard: C70600 is governed by ASTM B16.5 for pipe flanges and flanged fittings, as well as ASTM B466 (for copper-nickel tube sheets, plates, and rolled bars).
UNS Designation: UNS C70600, part of the Unified Numbering System for copper alloys.
Other Standards: May comply with ASME B16.5, ISO 9001, or marine-specific standards like ABS (American Bureau of Shipping) or DNV GL (Det Norske Veritas).

4. What is the application of C70600 Copper Nickel Flange ?
Marine Industry:
Shipboard piping systems (sea water cooling, ballast lines).
Flanges for heat exchangers, condensers, and seawater pumps.
Offshore platforms and subsea equipment.
Industrial Applications:
Chemical processing plants (corrosive fluid handling).
Power generation (cooling systems in thermal or nuclear plants).
Desalination plants (resistant to chloride-induced corrosion).
Oil & Gas:
Pipelines and fittings in offshore oil rigs.
High-salinity or sour gas environments.
5. What are the advantages of C70600 Copper Nickel Flange?
Exceptional Corrosion Resistance:
Highly resistant to seawater, chloride ions, and biofouling (algae/marine growth).
Resists erosion-corrosion (e.g., from high-velocity fluids) due to iron and manganese additions.
Durability & Strength:
Maintains mechanical properties across a wide temperature range (-196°C to 300°C / -321°F to 572°F).
Suitable for high-pressure applications (e.g., Class 150 to Class 2500 flanges per ASTM B16.5).
Ease of Fabrication:
Weldable (using nickel-based filler metals) and machinable.
Can be formed or cold worked for custom geometries.
Non-Magnetic & Non-Sparking:
Safe for use in environments with explosive gases or sensitive electronics.
Long Service Life:
Reduces maintenance costs in harsh environments compared to carbon steel or other alloys.
