High Silicon Cast Lron

High silicon cast iron anodes are widely used as a corrosion-resistant material due to their low cost and abundant raw materials. They have been the main anode material for cathodic protection since the 1950s. High silicon cast iron anodes have good corrosion resistance because the surface of the anode can form a stable silicon dioxide film, which is effective in both seawater and freshwater. We recommend using chromium or molybdenum chromide to prevent hypochlorite corrosion.

Product Details

High silicon cast iron anodes are widely used for cathodic protection of surface structures, buried pipelines and cables, etc. It is a low-resistance, low-consumption, and low-energy-consumption anode. The silicon iron anodes we produce meet the ASTM5-18-86 (Grade 3) standard. This anode is cast using cold casting technology, which has better quality and performance than those cast using sand molds. The following specifications of anodes are available:

Compared to solid rod anodes, tubular anodes have the following advantages:
1. Reduce the electrolysis of the anode.
2. Increase the surface area to weight ratio, thereby reducing the current density, which is conducive to the diffusion of the generated gas. This is important for deep installation.
3. The cable connection position is in the center of the tube to increase the current dispersion and release the end charge

Piggy Back Flexible

Flexible anode is a new material that has been developed recently, with its main application being cathodic protection of storage tanks and buried pipelines. It has a very low consumption rate and high current capacity.

Deep Well Anode

Deep well anodes are used as the anodes for cathodic protection by external current, referring to the anode bed located at a distance of no less than 15 meters from the ground surface. It is relative to the shallow buried anode.

Platinum Anode

Platinum anode is coated with A layer of platinum on titanium, niobium and other substrates, when used as an anode, titanium and niobium form a stable oxide layer, these oxides are stable to titanium up to 12V, niobium up to 90V, the consumption rate of platinum plating anode is 6-10mg/A•a, platinum plating anode is used in silk or screen, platinum plating anode is suitable for freshwater or seawater use, Not suitable for soil, can be applied to condensers, pumps, heat exchangers, ships and so on.
