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.

Everyone is aware of the extreme financial penalties and, more importantly, the potential dangers associated with sudden or long-term heat exchanger tube failures.
OK, you’ve seen the name before and heard of CTI Full Length Tube Liners and CTI Shield/Seals. Many of you have actually used CTI’s services and had great success with the company’s heat exchanger restoration. To a great many of you, thin-walled alloy tube liners are still a mystery.
CTI developed a tube repair technique recognized as one of the most widely used, cost-effective systems in the world. The thin-walled Shield/Seals propelled CTI’s success in offering cost-effective solutions for equipment life extension. BIC Magazine recently visited with Terry Quinn, CTI sales manager, to discuss Full-Length Tube Liners.
Every fixed equipment, mechanical and/ or reliability engineer, corrosion specialist, inspector, etc. at refinery, chemical and petrochemical plants is aware of the extreme financial penalties and, more importantly, the potential dangers associated with heat exchanger tube failures.
Being a leader in the worldwide heat exchanger repair business for almost 40 years, you tend to notice trends that happen from time to time. One trend that is occurring more frequently of late is the vintage of the exchangers that are in need of repair. In the past few years there has been an increase of premature tube failures on heat exchangers that are only a couple years old.
Back in 2012, a large oil refinery in Singapore — one of the largest in Asia — was experiencing premature failures of its splitter air-fin coolers, resulting in emergency shutdowns and lost revenue.
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.
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.
In August of 2006, Detroit Edison contacted CTI Industries of Orange, CT about the possibility of restoring failed tubes at St. Clair Station’s, Unit 7, #5 IP Feedwater Heater.
This paper references slide 12 of the slide presentation for explaining further the Ameren “5%-Rule” expected remaining service life criteria evaluation for the AmerenUE Labadie unit 4, 5A LP feedwater heater.
