During startup and commissioning, heat exchangers are vulnerable to contamination from debris inside newly installed pipelines.
Common contaminants include:
weld slag
rust particles
construction debris
gasket fragments
If these materials enter the exchanger, they may reduce heat transfer efficiency and increase maintenance requirements.
To minimize startup risks, many facilities install temporary cone strainers upstream of the heat exchanger.
Temporary cone strainers are designed for short-term startup filtration and are commonly used during:
flushing
commissioning
startup circulation
Proper mesh selection and differential pressure monitoring help maintain stable startup conditions.
