Retubing is a proven method to restore the performance and extend the service life of heat exchangers. Over time, tubes can suffer from fouling, corrosion, erosion, or mechanical damage, leading to reduced efficiency or leakage. During retubing, the old tubes are carefully removed, tube sheets are cleaned and prepared, and new tubes are installed, expanded, and sealed to OEM specifications. This process restores the unit to like-new condition, improves reliability and minimises the risk of unplanned downtime – all without the need to replace the complete bundle or heat exchanger.
Tube repair and retubing in heat exchangers are proven measures for restoring full performance. Damaged or corroded tubes are repaired or completely replaced without having to replace the entire heat exchanger. This prevents leaks, increases operational safety, and extends the service life of the system in a sustainable manner cost-effectively and in a resource-efficient way.
