Zinc alloy sacrificial anode

The cathodic protection method of zinc anode is to connect a metal or alloy that is more likely to lose electrons to protect steel equipment. For example: the protection of steel gates, some use this method. It is a more active metal, such as zinc, which is attached to the steel gate. In this way, when galvanic corrosion occurs, the metal that is more active than iron is corroded, and iron is protected. Usually, a certain amount of zinc blocks are installed at the stern of the ship and below the waterline of the hull to prevent the hull from corroding. This is the method used.
Product features: low self-solubility, high current efficiency, wide application range.
 At present, electrochemical protection is not only used to protect steel equipment in sea water or rivers, but also to prevent corrosion of cables, petroleum pipelines, underground equipment, and chemical equipment. Aluminum alloy sacrificial anodes are suitable for cathodic protection of metal corrosion protection for ships, mechanical equipment, marine engineering and seaport facilities in seawater media, pipelines, cables and other facilities in sea mud, and soil media with low resistivity.

Precautions for use: 1. Keep the surface clean. 2. When using in the soil, the soil resistivity should be less than 15 ohm·m, and it is recommended to use it with a special packing package

Aluminum sacrificial anode Specifications:

 

Sacrificial Aluminium Anodes are simple and economical that it could be performance under a variety of environmental conditions, after proper installation that Aluminium anodes will performance efficiently and continuously without any attention for CP systems.The performance of Aluminum anode is affected by the chemical composition of the alloy.

Aluminum anode chemical composition type:

Al-Zn-In, Al-Zn-In-Cd, Al-Zn-In-Sn, Al-Zn-In-Si, Al-Zn-In-Sn-Mg, Al-Zn-In-Mg-Ti.

 

We have different alloy series to meet customer's request. The below specification only are small part of our products list, we have much more specification size, and also special shape, size and chemical composition anodes can be manufactured according request.

 

Aluminum sacrificial anode Application :

Aluminum anodes for defend the corrosion of steel structures in seawater and fresh water environment, they  are widely used on ship hull, ballast tank, harbor dock, offshore platforms, oil tank, Pipe in the seawater, etc.

Aluminum anodes corrode much more easily than the materials they are protecting, drawing the corrosion away from equipment.

Sacrificial High Potential Sacrificial
 Magnesium Anode
 
Sacrificial Magnesium Anode Specifications:
 
High Potential HP Magnesium anode are made from high-purity magnesium, they could produce a higher driving voltage than conventional magnesium anodes, so high potential magnesium anodes are suited for structures buried in soils with resistivities in excess of 2,000 ohm/cm.
We adopt special technology, the anodes have superior electrochemical properties, in practical experience, the actual measured driving potential is between -1.8V to -1.85V, thus provide most powerful protection to the targeted structure. The anodes are consumpted uniformly, thereof the anodes have a longer working life.
 
Our magnesium anode all manufactured and tested according to latest international standards, such as ASTM B843 and ASTM G97,It’s available from both M1C( high Potential)or AZ63B(standard Potential)magnesium anode.
Sacrificial Magnesium Anode Application :
High Potential HP Magnesium anode fight corrosion effectively and economically, and are commonly used in marine environments, soil environment,etc..They protect a variety of steel structures in salt, brackish and fresh water, including: Buried Oil gas Pipelines, Storage tanks, Boats, Ballast tanks, Bulkheads, Pilings, Heat exchangers, etc.
 
Magnesium anodes corrode much more easily than the materials they are protecting, drawing the corrosion away from equipment.
