Copper Nickel Threaded Flange: The Ultimate FAQ Guide

 

 

What is an ASME B16.5 Compliant Copper Nickel Threaded Flange?

These are special types of copper nickel flanges where the internal bore has threads that match the male threads of copper nickel pipes.

Additionally, these copper nickel pipe flanges conform to the ASME B16.5 standard specifications.

Is there a Difference between Cupronickel Threaded Flanges and Screwed Flanges?

No.

Due to the existing threads and the installation procedure, at times you can also refer to Cupronickel threaded flange as Cupronickel screwed flange.

Cupronickel Threaded Flange is made from which Material Grade?

CuNi threaded flange is made from either:

  • Copper Nickel 90/10 (C70600 ), or
  • Cupro Nickel 70/30 (C71500)

Where is Cupronickel Threaded Flanges used?

You can use Cupronickel threaded flanges with pipes having external threads. It is because you will use the threads when connecting flanges to the piping system.

You can use the copper nickel threaded flanges in shipbuilding, desalination plants, power generation plants, offshore oil platforms, water piping, etc.

Furthermore, Cupronickel threaded flange is suitable in:

  1. Highly explosive or flammable areas where welding can cause fire – with CuNi threaded flanges, you don’t need welding
  2. Small diameter and high-pressure applications

How do you Connect CuNi Threaded Flange to Pipe?

First, you need a copper nickel pipe with matching external threads to that of the CuNi threaded flange.

Screw-in the Cupronickel threaded flange onto the copper nickel pipe.

What are the Benefits of Copper Nickel Threaded Flange?

  1. Easy to install and uninstall – simply screw or unscrew the copper nickel threaded flange
  2. Provides tight and secure flanging mechanism in the piping system
  3. No need for any form of welding since the flange uses threads to connect the piping system

What is the difference between Cupronickel Threaded Flange and Slip on Flange?

Cupronickel threaded flange is similar to Cupronickel slip on flange on virtually all aspects.

However, Cupronickel threaded flange has threads on its internal bore. This is not the case for the Cupronickel slip on flange.

Which Thread Types Do CuNi Threaded Flanges come with?

They come in either NPT or BSPT thread types.

Remember, the National Pipe Taper (NPT) is an American standard although it has been adopted globally.

On the other hand, British Standard Pipe Taper (BSPT) is common within the European economic region although it has been adopted globally too.

The difference between NPT and BSPT is the configuration of the thread form and pitch.

What is Copper Nickel Threaded Flange Specifications?

Whenever you are specifying the copper nickel threaded flange, the focus should be on the following:

  1. Material grade
  2. Thread type
  3. Dimension specification
  4. Class or pressure rating
  5. Flange face type

How many Types of Copper Nickel Threaded Flanges are there?

Broadly, you can classify copper nickel flanges depending on the location of the threads.

You can choose from CuNi plain threaded flanges, CuNi male threaded flanges or CuNi female threaded flanges.

Does Cupronickel Threaded Flange has Flat Face and Raised Face?

Yes.

You can get a flat face (FF) or a raised face (RF).

What are the Characteristics of Copper Nickel Threaded Flange?

  1. Threads for connecting flange to the pipe system
  2. High stress and pressure resistance
  3. Resistance to biofouling, corrosion, and erosion
  4. Easy to install and uninstall in the piping system

Are CuNi Threaded Flanges suitable for Environment with Thermal Cycles?

No.

The thermal cycles will loosen the copper nickel threaded flange.

It is for this reason that copper nickel threaded flanges are recommended for applications with stable working temperature.

How many Bolt Holes should CuNi Threaded Flanges have?

The number of bolts will depend on the size and pressure rating of the copper nickel threaded flange.

For instance, a large CuNi threaded flange will have more bolt holes and vice versa.
