What Does Fire Deluge System Mean?
A fire deluge system refers to a water sprinkler dispersion system that does not incorporate pressurized air to open the sprinkler heads. These systems are prone to corrosion because they contain moisture and may be set off more frequently than traditional sprinkler systems.
Corrosionpedia Explains Fire Deluge System
Because they are used as a hazard prevention or elimination device, fire deluge systems must be frequently inspected for corrosion infiltration. The presence of significant corrosion can negatively impact the operation of the system and cause it to fail when it is needed most. A failure can result in the loss of human life, physical assets and property.
There are three main corrosion classes that can be identified during a routine inspection of a fire deluge system:
- Class I - Minimal damage to pipe array, can be rectified by flushing alone
- Class II - Medium damage is present, requiring the replacement of some pipes but not all
- Class III - Considerable damage and rust deposits are present, requiring the replacement of all system piping
