Rocore’s CTI Group offers two basic types of repair services for condensers and heat exchangers. These patented tube repair techniques have successfully been applied to a wide variety of exchangers - fin-fan air coolers, process shell-and-tube exchangers, hydrogen coolers, HP feedwater heaters and many more.

For those units suffering from inlet-end erosion, Stress Corrosion Cracking, crevice corrosion or any problems related to the tube-ends, CTI offers its most cost-effective tube repair, the CTI Shield/Seal™, also known as a tube insert or ferrule.  Although Shields are typically only 6" - 12" long,, some applications have required Shield lengths up to 14 feet!

Unfortunately, some exchangers suffer from full-length problems. In this case, CTI Full Length Tube Liners™ can be a very attractive alternative to a partial or full re-tube.

Tube Liners

The patented CTI tube liner was 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 provide heat transfer surface contact with the existing tubes. Finally, the Liners are cut, trimmed and roller expanded at the tubesheet areas, resulting in fully restored tubes.
