Monel 400 Flanges

Riddhi‍‌‍‍‌‍‌‍‍‌ Siddhi Metal Impex is a reliable source of industrial-grade piping systems for harsh environments as a Monel 400 Flanges manufacturer, using the nickel–copper alloy to make the flanges which is a very good resistive to corrosion and has high mechanical strength. Monel 400 is a very good performer in seawater, steam and other chemical environments while it is still tough at very low or very high ‍‌‍‍‌‍‌‍‍‌temperatures.

Extremely‍‌‍‍‌‍‌‍‍‌ resistant to seawater, acids and corrosive process media
Even to sub-zero temperatures the material keeps its strength and toughness
The good thermal conductivity makes the material suitable for the heat-transfer applications
The flange can be available in weld neck, slip-on, socket weld and threaded types
Made by following the specifications of ASTM B564 and ASME ‍‌‍‍‌‍‌‍‍‌B16.5

Monel‍‌‍‍‌‍‌‍‍‌ 400 flanges find application in marine systems,chemical processing units, oil refineries, and offshore installations. Getting connected with a reliable B2B Platform for procurement allows one to have tailored dimensions, pressure classes, and facing choices along with the quality checks and smooth transportation being offered for the non-stop industrial ‍‌‍‍‌‍‌‍‍‌activities.
