10 Facts About Corrosion from ECS

10. Corrosion is considered normal and unavoidable.

9. Virtually all water based fire sprinkler systems are subject to attack by oxygen corrosion.

8. Factors that accelerate corrosion failures include oxygen, increased activity, trapped air and water and high temperatures.

7. Corrosion is caused by a combination of either water, iron, oxygen and/or bacteria.
If you eliminate one of these, then you lower the possibilities of corrosion

6. There are three classes of corrosion.
Class I – Little damage is found the pipe array should just be flushed.
Class II – Medium damage is found, so that some but not all pipes show increased damage, those pipes must be replaced.
Class III – Considerable corrosion and deposits the complete pipe array or parts of it must be replaced.

5. Average service life of fire sprinkler systems
Wet system is about 15-25 years
Dry system is about 10-15 years

4. Risks associated with corrosion are:
Life safety risk
Structure and property risk
Repair and replacement cost
Business continuity risk

3. The most cost effective method of eliminating corrosion in fire sprinkler systems is to remove the corrosive gas.

2. Nitrogen Generation Systems are designed to replace the oxygen.

1. Using 98% Nitrogen gas over compressed air increases the life expectancy of a dry fire sprinkler system.
