Canistered Cast Iron Anode consists of high silicon cast iron anode, coke, vent-pipe and outer steel pipe. The anode, Ф50mm×1500 or Ф75mm× 1500 mm, is fixed in the center of steel pipe, annulus filled and tamped with carbonous backfill.

It has the advantage of low consumption and grounding resistance, saves a lot of time of installing the anode in the field and ensures the quality of the installation. In sea water or fresh water, we suggest using high silicon cast iron alloy containing of chromium or chromium molybdenum to resist the corrosion of chlorine.
