Product Description

Magnesium Ribbon Anode Used In Long - Distance Pipelines For Cathodic Protection

 

Introduction:

 

The strip-shaped magnesium anode is made of pure magnesium or magnesium-manganese alloy cold-rolled and pressed. The open-circuit potential (reference electrode Cu/CuSO4) is -1.7V, and the mass per unit length is 0.37kg/m. used in the environment.

 

The output current of the magnesium ribbon is 10mA/m in soil with a resistivity of 50Ω·m and 3mA/m in fresh water with a resistivity of 150Ω·m. The surface area of ​​strip-shaped magnesium anode of the same mass is much larger than that of ingot-shaped magnesium anode. For example, the surface area of ​​11kg magnesium ingot is 0.27m2, while the length of 11kg magnesium strip is 30m, and the surface area is 1.9m2, which is 7 times that of the former.

 

The anode output current is proportional to the surface area and inversely proportional to the resistivity. Anode quality determines anode life. The local soil resistivity should be considered in the design, and the service life of the magnesium tape should be considered to be equivalent to the service life of the pipeline when it is wound on the pipeline in the crossing section or the casing.

Advantages:

 

From raw materials - semi-continuous magnesium alloy rods - extrusion - forming, the factory is independently produced and the internal composition is controllable. Extruded ribbon magnesium anode, very flexible. Due to the higher area-to-weight ratio of the magnesium ribbon, it can provide higher current output than other anodes.

 

Application:

 

Magnesium Ribbon Anode used in high resistivity environments, protection of pipelines in casings, temporary cathodic protection of pipelines, protection of storage tanks and pipe networks, grounding grids to prevent strong electrical interference, etc.
