Copper Nickel Blind Flange

A blind flange is a solid piece of metal made from copper nickel alloy. Unlike other types of flanges, it does not have holes on its surface for a free flow of fluids (liquid or gases).The only holes on copper nickel blind flange are for bolts that you will use to secure it to the piping system.

Uses of Copper Nickel Blind Flanges

The Copper Nickel Blind Flange blocks a section of a piping system. Or, it terminates the end of a pipe.

This means that the use of the Copper Nickel Blind Flange is the same as that of a pipe cap or pipe plug.

Therefore, the Copper Nickel Blind Flange is useful in the following situations:

  • Strength or tightness testing of Copper Nickel piping systems
  • Isolating certain piping systems
  • Isolating equipment or devices in a piping system
  • Repair and cleaning of piping systems
How to specify a copper nickel blind flange?

  • Grade or pressure class
  • Flange face type can be flat face (FF) or raised face (RF)
  • Size can vary between 1/2 inch and 24 inches
