What are the Alloy 20 flanges maintenance needs?
Flanges must be maintained regularly to ensure their durability and long service life without any issues.Some maintenance needs of alloy 20 flanges are:
- Conduct routine visual inspections to check for signs of surface damage or corrosion.
- Clean the flange to remove any surface contaminants.
- Make sure only compatible materials are used as seals, gaskets and fasteners to prevent galvanic erosion.
- You can consider giving periodic passivation to the alloy 20 plate flanges to restore and enhance their corrosion resistance.
- Follow a regular maintenance schedule to identify any potential issues and overcome them before they get larger.
