When installing a piece of metal tubing in a bonded clamp, what must be done to the area at the clamp's location?

When installing metal tubing in a bonded clamp, it is essential to remove paint or oxide film from the area at the clamp’s location. This is crucial because any contaminants, including paint or oxidation, can interfere with the electrical conductivity and bonding characteristics necessary for the clamp to perform effectively. A clean surface ensures that the clamp makes proper contact with the metal tubing, preventing issues that could arise from inadequate bonding, such as corrosion or structural failure.

The presence of paint or oxide can create an insulating barrier that disrupts the intended mechanical and electrical connection, which is particularly important in applications involving bonded structures where conductivity is critical for performance and safety. Thus, preparing the surface by removing any paint or oxide allows for optimal function of the bonded clamp and contributes to the overall integrity of the assembly.
