What is the best way to maintain Inconel rivets?

By maintaining Inconel rivets, you can ensure their durability and optimal performance. Some maintenance tips are:

  • Inspect the rivets regularly and check if they have not loosened over time. You should also check the rivet surface for signs of wear, damage or corrosion.
  • If they are continuously used in corrosive environments like chemicals or seawater, then apply a protective coating.
  • Ensure the rivets are properly tightened during installation and flow the manufacturer's torque value.
  • If you notice any issues, like damage or degradation, get the rivet replaced immediately. These can interfere with the structural integrity and affect its performance.
  • Follow the manufacturer's guidelines and consult with them, if required.
