Monel is a nickel-copper alloy (approximately 67% nickel, 30% copper) that offers exceptional corrosion resistance in some of the most demanding environments in industry. Monel flanges are the preferred choice for:
* Seawater and marine environments where standard stainless steel would fail
* Hydrofluoric acid service in chemical processing plants
* Alkaline and saltwater desalination systems
* High-temperature applications up to 1000 degrees F
* Oil and gas production in sour gas environments
All Monel flanges are manufactured to meet or exceed the following standards:
* ASME B16.5 - Pipe Flanges and Flanged Fittings (NPS 1/2 through 24)
* ASME B16.47 - Large Diameter Steel Flanges (NPS 26 through 60)
* ASTM B564 - Nickel Alloy Forgings
* API 605 and MSS SP-44 for large diameter applications
* Monel 400 (UNS N04400) - Standard grade with excellent corrosion resistance
* Monel K-500 (UNS N05500) - Age-hardenable grade with higher strength and hardness
