D Type Sacrificial Anode Cathodic Protection Magnesium 9D2-2 For Pipelines

D Type High Potential Magnesium Anode Widely Used In The Protection Of Metal Components
 
Introduction:

The main characteristics of high-potential magnesium alloy sacrificial anodes are large electricity per unit mass, high potential, small specific gravity, relatively negative potential, high driving voltage to Fe, low current efficiency, etc., especially suitable for high resistivity media. Both the American standard ASTM8431993 (2003) and the Chinese standard GB/T177312004 require that the current efficiency of high-potential magnesium alloy sacrificial anodes be higher than 50% and the potential higher than 1.77 V.

Specification:

Advantage:

A: The one-time investment cost is low, and there is basically no need to pay maintenance costs during operation
B: The utilization rate of the protection current is high, and no over-protection will occur
C: No interference effect on adjacent underground metal facilities, suitable for plant area and long-distance pipeline without power supply, as well as small-scale decentralized pipeline protection
D: It has the function of both grounding and protection
E: The construction technology is simple and usually does not require special professional maintenance and management.

Application:

Magnesium anode is the use of magnesium negative potential, its potential is lower than steel, can be used to protect onshore pipelines and other buried structures, such as oil pipelines, natural gas pipelines, underground oil tanks, oil platforms, water heaters, and for the protection of fresh water ships in the environment.
