Material Of Monel Check Valves

Monel alloy is a Nickel alloy material with the addition of:

Copper (Cu)

Silicon (Si)

Manganese

These materials are also known as Monel Alloy 400 and Monel Alloy K500

Material Features:

Monel alloy has an excellent anti-corrosion performance in the reducing acid medium, especially have excellent corrosion resistance in high-temperature hydrogen fluoride and hydrofluoric acid solution, and resistant to any density of hydrofluoric acid solution corrosion. Mainly applies in high-temperature hydrogen fluoride gas and hydrofluoric acid solution condition, and its corrosion resistance is better than copper-based alloys when used in seawater.

Cautions Of Monel Check Valves

Ease of manufacture: trade-off between castability and weldability

Pitting can be a problem at low velocities

Don't be used as the trim of austenitic stainless valves

P/T rating class 300=600 psi CWP

Cost effectiveness need consideration

Application Of Monel Check Valves

Petrochemical plant

Refinery

Power plant

Water treatment plant

Marine exploitation

Additional Uses & Comments Of Monel Check Valves

Variety of wrought/ bar specifications available, good for trim material. Excellent strength from K500

Reasonable castability with the suitable design and higher Si content

Weldable with lower Si content

Excellent for hydrofluoric & other acids (Exclude nitric acids)
