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.

What things should I keep in mind when installing UNS N08020 slip on flange?
  • While installing ASTM B462 UNS N08020 slip on flange, confirm that its size matches the pipe size and schedule.
  • Consider the specific flange face type required for your application.
  • Proper fitting of the slip on flange is crucial to ensure there are no leakages.
  • Choose a suitable gasket material that is compatible with both flange material and the conveyed fluid.
  • Use a torque wrench to tighten the flange bolts as per the recommended value.
  • Employ proper welding technique that is compatible with UNS N08020. The heat input must be controlled to avoid flange distortion.
