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. Advertisement 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 Advertisement Share This Term> Related Terms Wet Fire Pipe Passive Fire Protection Coating Pipeline Inspection Tool Water Storage Tank Hazardous Combustion Product Hydrocarbon Fire Protection Dry Fire Pipe Hydrocyclone Related Reading High Pressure Fastener Coating Practices Under Fire: Ian MacMoy Speaks Out Gas Pipelines: Internal Corrosion Protection and Fire Prevention Field Results: Improving Water System Efficiency & Corrosion Resistance Lessons from a 35-Year-Old Water Heater Corrosion Costs & Recommended Practices for the Water Industry Combating Wet Insulation and CUI with Aerogel Coatings Tags Corrosion Markets Infrastructure Equipment Industries General Equipment Water and Wastewater Trending Articles Corrosion An Introduction to the Galvanic Series: Galvanic Compatibility and Corrosion Chemical Compound 5 Most Common Types of Metal Coatings that Everyone Should Know About Asset Management Understanding Aluminum Corrosion Asset Management If Copper is a Noble Metal then Why Are My Pipes Corroding?
