composite slip onflange is made of inner flange , also called collar & backing flange (loose flange).The collar is welded with copper nickel pipes , the backing flange can be active. Collar is the sealing surface, the role of the backing flange is to press them. Because of collar is blocked, backing flange does not contact with the media. Cuni slip on flanges connections are applied, in low-pressure and non critical applications, and is a cheap method of flanging , normally used in shipment.

Application of Copper Nickel CuNi Slip On Flanges
Because of the specific copper nickel properties, this alloy of copper is used in different industries that include:
- Shipbuilding and repair
- Desalination plants
- Offshore oil and gas platforms and processing and FPSO vessels
- Power generation
- Seawater system design
- Seawater system components
- Hulls of boats and ships
- Armanents industry
Cupro Nickel is extremely resistant to corrosion in the water for the reason that the electrode potential of it has been adjusted to become neutral in connection with seawater. In this reason, copper nickel is used for heat exchangers, piping and condensers in the seawater systems.
