Characteristics of Weld Neck Flange
- Resistance to biofouling, erosion, stress and corrosion
- Can withstand high pressure
- Suitable for applications with fluctuating temperature
- Guarantees a sturdy connection
- Can withstand the turbulent flow
- Initial installation cost is high however CuNi weld neck flange is long-lasting
How does Copper Nickel Weld Neck Flange Work?
- Cupronickel weld neck flange is butt welded to copper nickel pipes for a seamless connection.
- It ensures seamless flow throughout the pipe, while minimizing possible turbulence, in high pressure and high-temperature applications.
- CuNi weld neck flange helps to transfer stress that could otherwise concentrate on the flange hub to the entire piping system. With this, the CuNi weld neck flange will withstand vibration and other devastating environmental conditions.
- Of course, the inside diameter of Cupronickel weld neck flange should match the inside diameter of copper nickel pipe or CuNi fitting.
