Heat Exchanger Bundles (Shell and Tube)

Take Note
There are some specific cases where the S-RBI assessment approach in IMS PEI changes, depending on the Equipment/Component type.
This section gives guidance for Heat Exchanger Bundles (Shell and Tube).

Define Asset – Step 1 

See Step 1.

Typically, the Heat Exchanger (HX) Channel and Shell Components will be monitored by different Circuits.

IF – Step 11 

See Step 11.

The Interval Factor is generated from the “full life” table.

Barrier Verification – Step 12 & Step 13 

See Step 12 and Step 13.

EVA is a statistical methodology that can be used to calculate and predict the corrosion for HX (Heat Exchanger) bundles.

In some cases, the channel is coated internally. In these cases, the use of CMLs is not normally the best way of managing internal corrosion monitoring, a recurring inspection Schedule with access to the inside should be considered.
