What is the anode ground bed resistance

What is the resistance of the anode ground bed? What is the effect of the potential level of the metal components?

With the improvement of people's understanding of anticorrosion, it is believed that the market of magnesium anode, aluminum anode and other anode materials will be increasingly extensive. The anode material can be better used in cathodic protection. The anode ground bed resistance can be set, and the anode material with higher negative potential than metal can be selected as the metal anticorrosion material. This chapter of Jiaozuo Ladbrokes light alloy for you to introduce what is the anode ground bed resistance, to help you understand the impact of the potential of metal components, if you have any doubts, Jiaozuo Ladbrokes light alloy welcome your call to consult!

Knowledge points

1: Anode ground bed resistance The anode ground bed resistance is set to reduce the consumption of external electric energy on the magnesium anode ground bed. A ground resistance of less than 1 ohm will be provided with the magnesium anode ground bed.

In order to ensure the effectiveness of the resistance of the anode ground bed, the distance between the magnesium anode ground bed and the underground pipe must be appropriate. Under normal circumstances, the safe distance between Yang pole bed and underground pipeline is between 300-500 meters. At the same time, it is also necessary to set the minimum protection potential, that is, the potential of the metal in full protection, its role is corresponding to the minimum protection current, to protect the metal.

2: the impact of the potential level of metal construction

For the metal to be protected, the negative potential of the metal must be higher than the minimum protective potential. However, too high a negative potential may cause hydrogen evolution on the metal surface (hydrogen evolution bubbles can destroy the metal surface insulation and cause corrosion), so we need to apply the maximum protective potential.
