CTI Industries, Inc. is a global technical service company that specializes in the restoration of condensers and heat exchangers. With its headquarters in Connecticut, CTI incorporates sales/service centers throughout the world, allowing for quick response times.
The repair techniques used by CTI are based on offering cost-effective solutions for equipment life extension, beginning with the “sleeving” of heat exchanger tubes.
Besides condensers, 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.
CTI offers two basic types of sleeving for the repair of condensers and heat exchangers.
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!
Some exchangers, however, suffer from full-length problems. In this case CTI Full Length Tube Liners™ can be an attractive alternative to that of a partial or full retube.
CTI has been of service to the electric utility, oil refining, commercial marine, chemical and petrochemical, fertilizer, desal and steel mill industries in over 50 countries worldwide.

In February 2014, a major South Texas oil refinery discovered severe damage (ID pitting) to their Air Cooler tubes while under inspection during a scheduled turnaround. In their present condition, the units were not suitable to be returned to service, putting the refinery – and the post T/A start-up – in jeopardy. Unfortunately, time was limited – and so were their options – since the situation was now “holding up the entire T/A”.
It is safe to assume that all plant engineers are aware of the extreme financial penalties and, more importantly, the potential dangers associated with heat exchanger tube failures.
Endesa’s Compostilla Power Plant is located in Ponferrada (León), Spain, commissioned in 1964. It is a coal-fired power plant with a capacity of 1292 megawatts spread across five (5) turbines, which are a combination of Westinghouse and Mitsubishi.
CTI Industries was contacted to consider installing our Full Length Tube Liners into the Main Condenser at Exelon’s Schuylkill Station in Philadelphia, PA. The condenser at the Exelon Schuylkill Station is an older vintage CH Wheeler, two pass divided water box configuration with 16,500 tubes. By Kevin Shugrue, CTI Industries
This paper discusses the failures, investigative techniques, probable root causes, and corrective measures evaluated and implemented to extend the service life of high pressure feedwater heaters at TVA's Allen Fossil Plant.
