- The constant expansion and contraction of heat exchanger tubes during several heating and cooling phases of an operation causes calcium deposits, scale formations, lyme accumulation and other contaminants that can lead to operational failures and faster deterioration of the operational system.
- This also causes alteration in the originally fabricated structure and damage the internals of the system.
- These deposits eventually clog the flow of the system and hence must be subjected to replacement, which is generally termed as Retubing Process.
The process of retubing services include:
- Tube removal
- Replacement of tube bundles / Tube sheet repair
- Hydrojetting (if necessary, also a precautionary action preferred by some)
- Tube installation
- Leak tests, and
- Scrap tube recovery
