High Silicon Iron Anodes are among the most common impressed current anodes used in groundbed construction. The high corrosion resistance of silicon iron and silicon chromium iron alloys effectively ensures lifetimes in excess of 20 years.
Silicon Iron Anodes can be used for onshore, seawater and freshwater applications. The most common areas of use are listed below:
Land Pipelines (u/g):
The anodes are installed in horizontal, vertical or deepwell groundbeds.
Jetties & Quay Walls:
The anodes are installed in horizontally in sea beds muds or anchored to the sea bed.
Sea Outfalls:
The anodes are installed in horizontal or vertical groundbeds on the foreshores.
Water Storage Tanks (Internal):
The anodes are suspended from the tank roof.
Water Storage Tanks (External):
The anodes are installed in horizontal vertical or deep groundbeds around tank.
The High Silicon Anodes manufactured by us two types.
: : Single Headed
: : Double Headed
