This video explains the main functions and practical uses of CuNi 70/30 forged socket weld flanges in a clear, step-by-step format. You'll see how these marine-grade flanges provide superior seawater corrosion resistance and anti-biofouling properties for shipbuilding, offshore platforms, and desalination plants. We demonstrate proper installation techniques, welding procedures, and maintenance considerations to ensure long-term performance in harsh marine environments.
