2200 Hour Corrosion Test

To begin corrosion testing, two raised-face FRP piping flange assemblies were delivered to ITI Anti-Corrision, Inc. for exposure to 2200±24 hours of ASTM B 117-03; Standard practice for operating salt spray (fog) apparatus.

The nuts/bolts/washers used on each assembly were coated with the Fluorokote #1® system.

The assemblies were visually examined for corrosion (ASTM D 610-01) at 1200±24 hours, 1800±24 hours, 2000±24 hours, with the full/final evaluations performed at 2200±24 hours.

Duration Position & Torque % of Rust & Visual Examples Per ASTM D 610-01
1200 ± 24 Hours Horizontal (Hand) ≤ 0.01%
Vertical (Wrench) ≤ 0.01%
1800 ± 24Hours Horizontal (Hand) ≤ 0.03%
Vertical (Wrench) ≤ 0.01%
2000 ± 24 Hours Horizontal (Hand) ≤ 0.3%
Vertical (Wrench) ≤ 0.1%
2200 ± 24 Hours Horizontal (Hand) ≤ 0.3%
Vertical (Wrench) ≤ 0.1%

The Horizontal/Hand Torque assembly was dissembled at the completion of the exposure with the nuts being easily unthreaded by hand with little effort.
