influence on corrosion of fire protection systems, BUT NOT AS the major

corrosion contributor.”

Corrosion Mitigation – FM Global (Datasheet 2-1)

22

For Wet Pipe systems (FM Datasheet 2-1, 2.2.1.8)

Remove trapped air from wet-pipe sprinkler systems. Install minimum 1/2 in. (13 mm) FM

Approved automatic air-release valves or FM Approved manual

valves at the system high points. Remove the air after each time the

system is drained and refilled.



23

For Dry and Pre-Action Systems using Nitrogen (FM

Datasheet 2-1, 2.2.1.10.1)

A. Pressurize the system using an FM Approved nitrogen

generator. Alternatively, nitrogen cylinders maybe used, or another suitable supply if

compressed air is provided as backup.

B. Black steel pipe is acceptable in dry-pipe and preaction sprinkler systems

if nitrogen will be used throughout the life of the system. If it

will not, use galvanized steel pipe.



24

For Dry and Pre-Action Systems NOT using Nitrogen (FM

Datasheet 2-1, 2.2.1.10.1)

A. Use galvanized steel pipe.

E. Avoid the use of rolled groove joints. Rolled groove joints in a dry

sprinkler system promote water accumulation that can result in corrosion sites.

F. In humid regions or in areas that are subject to rapid drops in temperature, install an

air-drying system …

H. Orient longitudinal pipe weld seam toward building roof;

at least 45° in relationship to the floor (for reference, the weld line points to the floor at 0°) to

mitigate pipe weld seam corrosion.

Non-Certified Sprinkler Testing

Flow Endurance Test - FAILED

• 13,8 bar pressure of water is applied for

a period of 30 minutes.

• Substantial deflector deformation

occurred in both samples.

After Before



Sprinkler Operation - FAILED

• Heat responsive element either

operated slowly or not at all.

• Lodgment occurred in a vast majority

of the samples tested.

• Water was discharged up towards

the ceiling rather than down towards

the fire.



Sealing Assembly - FAILED

• Use of an O-ring seal banned

since 10+ years.

• Non-operation as well as leakage

can occur in field installation

environments.
