Monel flanges are widely applied in the pipeline, pressure vessels, heat exchangers, pumps, and valve assemblings that are subjected to hostile conditions. They are especially appropriate in the service of saltwater and chemicals due to their excellent resistance to corrosion, erosion, and stress corrosion cracking. Monel flanges are also custom-manufactured to special engineering requirements per drawings and technical specifications.

Key Features of Monel Flanges
Monel flanges are chosen because of its high mechanical properties and the ability to withstand the adverse environment which is quite demanding in nature.
- Extraordinary seawater, acid and alkaline medium resistance.
- Excellent mechanical strength over extensive temperature interval.
- Superior resistance to corrosion, pitting and stress corrosion cracking.
- Appropriate to high pressure and high temperature operations.
- Extensive life time and less service needs.
These are some of the aspects that render Monel flanges a reliable choice in critical piping and fluid-handling systems of the industry.
Besides Monel, flanges we also offer a large variety of Stainless Steel Flanges and Super Duplex Flanges to meet the needs of multi-material-flange projects so that buyers can obtain both corrosion-resistant and high-strength flange solutions in a single production source.
