Need a dependable monel flange? Monel Flanges on MetalMitra come in all standard face types and pressure classes to ASTM / ASME SB 564, ready for reliable pipe-to-pipe and pipe-to-equipment joints.

Monel Flanges are forged or machined components used to connect pipes, valves, pumps and equipment, allowing easy assembly, inspection and maintenance of piping systems.

Monel alloys are nickel-copper alloys known for high strength and excellent resistance to seawater, hydrofluoric acid, alkalis and many reducing environments.

Available forms & variants

  • Weld Neck Flanges — Butt-welded flanges for high-pressure and high-temperature service.
  • Slip On Flanges — Slip over the pipe for easy alignment and welding.
  • Blind Flanges — Solid flanges used to close pipe ends and openings.
  • Socket Weld & Threaded Flanges — Compact connections for smaller bore piping.
  • Lap Joint Flanges — Used with stub ends for easy alignment.
  • Spectacle & RTJ Flanges — Positive isolation and high-pressure sealing.

Performance highlights

  • Seawater Resistance — Excellent performance in marine and seawater environments.
  • Acid & Alkali Resistance — Good resistance to hydrofluoric acid and alkalis.
  • High Strength — Good mechanical strength and toughness over a wide temperature range.
  • Low-Temperature Toughness — Retains ductility at sub-zero temperatures.

Typical applications

  • Marine Engineering
  • Chemical Processing
  • Hydrocarbon Processing
  • Oil & Gas
  • Pumps & Valves
