The patented CTI Liners ^tm were developed for those units that suffer from full-length erosion/corrosion, pitting, general wall thinning and/or an overage of plugged tubes.

Tube I.D.'s are cleaned and the "Liners" (thin-walled tubes) installed. They are then hydraulically expanded their full length to make intimate contact with the existing tubes. Finally, the liners are trimmed and roller expanded at the tubesheet areas, resulting in fully restored tubes.
 

1. The reduction of circulating water velocity by restoring plugged, leaking tubes to service
2. The restoration of tube-end erosion/corrosion.
3. Other benefits can include the installation without the removal of the waterbox or at low load.
4. The ability to change alloys on the I.D. of the Tube
