"After several years of technical research and numerous market surveys we have established that there are only two means by which to repair condenser tubes reliably. The first method is to replace the tubes. The alternate method of Shield/Seal repair has proven to be the most effective and technologically sound means of not only repairing, but also significantly extending the service life of condensers."

The United States Navy

"The first condenser which was sleeved was intended to be a short term five (5) year fix. These same tubes are still in service twenty (20) years later with no problems."

"CTI demonstrated excellent technical knowledge . . . A credit to your company . . . Thanks for sending such capable personnel to help return the nuclear plant to an operational status."

"...It took four weeks to install all the inserts (Shield/Seals) compared with an estimated 240 weeks to partially retube 120 units. The cost comparison for partial retubing of exchangers versus the actual cost for using inserts was dramatic."

Saudi Arabian Oil Co. (ARAMCO)

". . . The sleeve repair has restored an otherwise non-functioning feedwater heater back to operational condition at a minimum of cost and time."

Baltimore Gas & Electric
C.P. Crane Station

". . . Condenser tube erosion can now be repaired by either complete retubing or by using metal tube inserts (Shield/Seals). Since tube insert repairs can be performed more rapidly, at approximately 10% of the cost of retubing, it is imperative that we use this repair technique."
