ODM AZ31 Magnesium Alloy Sacrificial Anode Cathodic Protection Bracelet
OEM/ODM Bracelet Magnesium Alloy Sacrificial Anode For Cathodic Protection
Product Description
The use of magnesium sacrificial anodes for cathodic protection is an effective method to prevent metal corrosion. Magnesium alloy sacrificial anodes have the following characteristics: good corrosion resistance, no external DC power supply, automatic operation after installation, no maintenance, and less floor space, the project cost is low, and there is no interference with the external environment. Magnesium sacrificial anodes are widely used in petroleum pipelines, natural gas, gas pipelines and storage tanks; ports, ships, subsea pipelines, drilling platforms; airports, parking lots, bridges, power plants, municipal construction, water treatment plants, petrochemical plants, smelters, Corrosion protection of gas stations, water heaters, heat exchangers, evaporators, boilers and other equipments.
Sacrificial anodes can be distributed in two ways: single or concentrated in groups. There are two types of anode embedding: vertical and horizontal. The embedding directions are axial and radial. The anode burial position is generally 3~5m away from the outer wall of the pipeline, and the minimum should not be less than 0.3m. The burial depth should not be less than 1m from the top of the anode to the ground. For northern areas, it must be below the frozen soil layer. When buried in groups, the anode spacing is 2~3m. In dry areas where the groundwater level is lower than 3m, sacrificial anodes should be buried deeply. For rivers and lakes, sacrificial anodes should be buried in safe parts of the riverbed (lake bottom) as much as possible to prevent damage during flooding and dredging. When using sacrificial anodes in cities and pipe network areas, it should be noted that there should be no other structures between the anode and the protected structure, such as cables, water, steam, pipes, etc.
The distance between the sacrificial anode (magnesium anode) groups on the pipeline is 1 to 2 groups/km for long-distance pipelines, and 200 to 300 groups are appropriate for urban pipelines and internal pipeline networks.
