Magnesium Anodes Cathodic Protection

Description

Product description:

A magnesium anode is a galvanic or sacrificial corrosion prevention device connected to steel structures to prevent or slow down rusting. Magnesium anodes create an easier and more attractive source of oxidation than the steel structures they are connected to. In this way they are consumed by corrosion instead of the structure — hence the name sacrificial anode. A magnesium anode is typically made up of an alloy composite of magnesium and other metals.

HappySoul provides the magnesium anodes available in a selection of prefabricated designs and weights to suit a wide range of installation requirements.

Application of 32Ibs/14.5kg 32D5 Bare Magnesium Anode

Magnesium anodes fight corrosion effectively and economically and are commonly used in marine environments. They protect a variety of steel structures in salt, brackish and freshwater, including:

1. Boats

2. Ballast tanks

3. Bulkheads

4. Water storage tanks

5. Pilings

6. Pipelines

7. Heat exchangers
