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.

Corrosion Mitigation – FM Global (Datasheet 2-1)
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.

Corrosion Mitigation – FM Global (Datasheet 2-1)
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.

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

Non-Certified Sprinkler Testing
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.

Non-Certified Sprinkler Testing
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.
