Feedwater Heater
Repair
Canadian Tubular Installations sleeving of high
pressure feedwater heaters is performed via
"hybrid" expansion - hydraulic expansion for the full
length of the sleeves followed by mechanical expansion
at each end.
This process will allow the feedwater heater to operate
efficiently for years. The sleeves will not only
protect damaged tubes from future failure, but will also
recover plugged tubes to active circulation.

Tube failures in
surface condensers are a significant reliability
problem for many industries. Tube failures
in feedwater heaters can also lead to serious
availability problems in three ways: replacement
power costs for a forced outage when a feedwater
heater cannot be isolated for repair, loss of
unit efficiency when a feedwater heater is
repaired with the unit on load, and secondary
damage if the repair is delayed until a planned
downtime. |
