Product Description
ASME B16.5 Class 150 CuNi 70/30 Copper Nickel Socket Welding Flange C71500 Forged SWRF
1. Product Description
Copper Nickel Flange is a pipe connection component made from copper-nickel alloy through forging, heat treatment, and precision machining. Common materials include B10 (90/10 CuNi, corresponding to UNS C70600) and B30 (70/30 CuNi, corresponding to UNS C71500). The nickel content in copper-nickel alloy significantly improves strength and corrosion resistance, while trace amounts of iron and manganese are added to enhance resistance to erosion corrosion. The flange can be used with copper-nickel pipes, copper alloy valves, and equipment, achieving tight connections through bolts and gaskets. Available flange types include Weld Neck, Slip-On, Blind, Socket Weld, Threaded, and Lap Joint. Products can be manufactured according to various international standards such as ANSI, DIN, EN, and BS, and can be customized upon request.
2. Product Applications
Copper Nickel Flanges, with their outstanding seawater corrosion resistance and anti-biofouling properties, are mainly used in the following applications:
Shipbuilding and Offshore Engineering: Ship seawater cooling pipelines, ballast water systems, bilge water systems, fire water systems, and offshore platform process piping;
Seawater Desalination Plants: Piping connections in multi-stage flash and reverse osmosis desalination systems;
Power and Energy: Condensers and cooling water circulation pipelines in coastal power plants;
Petrochemical: Heat exchangers, condensers, and process piping in refineries and chemical plants;
Marine Aquaculture and Seafood Processing: Seawater transportation pipelines and equipment interfaces;
Other Industrial Fields: Pharmaceutical, food, metallurgy, construction, and other piping systems with high corrosion resistance requirements.
3. Product Advantages
Strong Seawater Corrosion Resistance: Exhibits excellent resistance to uniform corrosion, pitting, and crevice corrosion in flowing seawater, static seawater, and brackish water environments, especially resistance to erosion corrosion.
Anti-Biofouling: Copper ions naturally inhibit the adhesion of marine organisms such as barnacles, algae, and molluscs, reducing the risk of pipeline blockage and lowering cleaning and maintenance costs.
Excellent Mechanical Properties: High tensile strength and yield strength while maintaining good plasticity and toughness, capable of withstanding high pressure and temperature fluctuations.
Good Weldability and Machinability: Can be welded by manual arc welding, tungsten inert gas welding, metal inert gas welding, and other methods, without complex post-weld heat treatment.
Wide Temperature Adaptability: Maintains stable performance from low to medium-high temperatures, suitable for various operating conditions.
Long Service Life: Service life in seawater environments can reach decades, with low life-cycle cost and significant economic benefits.
Non-Magnetic: Suitable for pipeline connections near magnetically sensitive equipment and instruments.
4. Product Functions
Pipe Connection: Reliably connects two pipes or pipes to equipment and valves, forming a complete piping system.
Sealing and Leak Prevention: With gaskets and fasteners, achieves long-term effective sealing under high pressure and corrosive media conditions, preventing leakage.
System Isolation and Distribution: Enables section isolation, zoning control, and medium distribution in pipelines, facilitating maintenance and inspection.
Flow Guidance: The tapered neck design of Weld Neck flanges provides a smooth transition of the pipe inner diameter, reducing fluid resistance and turbulence.
Structural Support: Provides rigid connections and support for piping systems, enhancing overall stability and seismic performance.
Galvanic Corrosion Prevention: When connected to copper-nickel pipes and copper alloy equipment, the materials match, avoiding galvanic corrosion caused by dissimilar metal contact.
