Alloy 20 Concentric Reducer is used to join pipe or tube sections on the same axis. They provide an in-line conical transition between pressurized pipes of differing diameters. A pipe reducer can be a single diameter change or a multiple diameter change. The pipes cannot recognize what the outside configuration of the pipe reducer looks like.

UNS	N08020
Werkstoff Nr.	2.4660

What are the characteristics of Alloy 20?

• Excellent general corrosion resistance to sulfuric acid
• Excellent resistance to chloride stress corrosion cracking
• Excellent mechanical properties and fabricability
• Minimal carbide precipitation during welding
• Excels in resisting corrosion to hot sulfuric acids

Uses of concentric reducers:

Some uses of concentric reducers are as follows:

Concentric reducers will transition gracefully between the piping and the pump.

The concentric reducers help in transporting slurries or abrasive liquids.

They are useful in services where cavitation is present.

When transporting between flanges or pipes of different ratings and wear protection is necessary, concentric reducers are ideal.

Concentric reducers are used in discharge of the pump.
