DESCRIPTION

AMAC distribute Anotec^TM Silicon Iron Anodes, manufactured to ASTM A518 Grade 3. We assemble anodes at our factory according to customer cable requirements. Our encapsulation process includes an epoxy resin and heat shrink cap to ensure no ingress of moisture.

APPLICATION(S)

Land Pipelines: Anodes generally installed in trench groundbed, individually buried in canisters, or installed in strings in deep well groundbeds.
Fresh Water Storage Tanks - Internal protection: bare anodes suspended from the tank roof.
External protection of storage tanks: Generally installed in canisters around the perimeter of the tank.
Offshore Pipelines - Jetties, Quay Walls: Generally supplied either bare or canistered for under mud or anchored on the sea bottom.
Sea Outfalls: Protected similar to a land based pipeline with the groundbed on the shore.

TECHNICAL INFORMATION

Direct current from impressed current CP systems prevent natural corrosion reactions. Typically a CP rectifier converts AC current to low voltage DC, which is delivered through cables to anodes bedded in the ground or in natural waters. The current leaves the anodes and passes through the earth toward the structure to be protected.
