When installing bonded clamps to support metal tubing, what precaution should be taken?

• A. Paint the tube for protection
• B. Remove paint or anodizing from the tube at clamp location
• C. Use a lubricant on the clamps
• D. Install the clamps without any modifications

Answer: (B)

When installing bonded clamps to support metal tubing, it is crucial to remove paint or anodizing from the tube at the clamp location. This is important because bonded clamps are designed to create a secure connection between the clamp and the tubing, allowing for better heat transfer and ensuring that the clamps hold the tubing in place effectively.

If paint or anodizing is left on the surface, it can interfere with the bond between the clamp and the tubing, potentially leading to inadequate support, increased vibration, or even failure of the assembly over time. By removing these coatings at the clamp locations, you ensure a clean metal-to-metal contact, which is essential for the clamp to function as intended and to maintain the integrity of the tubing system under various operational conditions.
