Magnesium Anode

Magnesium Anode

Our company produces magnesium alloy sacrificial anode by using high quality raw materials, mature production technology and advanced equipment inspection, to ensure that every anode is in line with national standards.

1. Small proportion, with a high chemical activity;

2. The potential is negative and the driving potential is large;

3. Large theoretical capacity and low polarization;

4. Especially suitable for high resistivity medium

(If the resistivity is greater than 100Ω•m, the ribbon magnesium anode is proposed)

Implementing Standards

GB/T 17731-2009 “Magnesium Alloy Sacrificial Anode”

GB/T 21488-2008 “Technical Specification for Cathodic Protection of Buried Steel Pipeline”

Scope of Application

Applicable to anti-corrosion protection of the oil, gas, water supply and drainage pipelines in soil medium, as well as the protection of harbor, ship, reservoir gate and other projects in water.

Magnesium Sacrificial Anode Classifications

1. Magnesium Alloy Anode for Oil Well Casing

2. Prepackaged Magnesium Alloy Sacrificial Anode with Backfill

3. High Potential Magnesium Alloy Sacrificial Anode D Type

4. Extruded Ribbon Type Magnesium Alloy Sacrificial Anode

5. Extruded Magnesium Anode Rod

Matters Need Attention in Use

1. Avoiding the collision with the steel structure;

2. Should be buried in the low-lying and damp places; the anode must be packed in filling bag before being buried in soil;

3. After being placed in the ground, the filling bag with anodes should be soaked with water before being covered by soil.
