Heat exchanger tube ferrules are inserts designed to either be sacrificial to the effects of inlet-end erosion, and impingement to induce a fluid to fall on corrosion the ID of a tube in a falling film exchanger; or to transfer extremely high heat past the tube sheet to the exchanger tubes.

Heat exchanger tube ferrule inserts will:

1. Protect inlet-end erosion & corrosion
2. Act as a protective layer
3. Reduce the medium impact
4. Transfer extremely high heat past the tube sheet to the exchanger tubes.

Protection against tube damage: Ferrules can help to protect the ends of heat exchanger tubes from damage due to vibration or thermal expansion. By providing a secure and rigid connection between the tube and the tube sheet, ferrules can help to prevent bending or distortion of the tube ends.

Overall, ferrules are an important component of many heat exchanger designs, helping to improve performance, prevent leaks, and protect against damage.
