Material Of Monel Check Valves

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

• Copper (Cu)
• Silicon (Si)
• แมงกานีส

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
