According to the diameter of the tube body, the aluminum alloy bracelet anode can be produced with a diameter from centimeters to several meters, and the weight can be from a few grams to hundreds of kilograms. Aluminum alloy bracelet anode has been widely used in oil transportation, gas pipelines, steel piles, etc. in the ocean. Practice has proved that high-quality products coupled with reasonable design and correct installation can make the metal pipelines in the ocean be uninterrupted protection, which can greatly extend the service life of metal.
The aluminum alloy sacrificial anode (referred to as aluminum anode) developed and produced by GB T 4948-2002 is suitable for the cathodic protection of metal corrosion prevention of ships, machinery and equipment, ballast water tanks, storage tank inner walls, coastal facilities, submarine pipelines, wharf steel piles, offshore platforms, cables and other facilities in seawater medium.
Aluminum anode is a kind of sacrificial anode, also known as aluminum alloy sacrificial anode, aluminum sacrificial anode, aluminum block, etc. It is called a sacrificial anode because it corrodes itself, sacrificing itself to protect a more important metal or device. Sacrificial anodes are made of materials that are susceptible to corrosion and are installed on protected bodies such as pipes, storage tanks, etc., to protect other parts of the system from corrosion. Sacrificial anodes are also known as galvanic battery anodes. Aluminum anodes are one of the commonly used sacrificial anodes and can be applied to many types of industrial equipment to protect them from corrosion.
Aluminum anodes are commonly used in ship hulls, water heaters, pipelines, storage tanks, and refineries.
The benefits of using an aluminum anode include:
1. Aluminum anode is more active than zinc anode or magnesium anode;
2. Unlike magnesium anodes, they do not produce sparks in salt or brackish water;
3. Aluminum anodes have a longer life and are the only type of anode that can be used in any body of water such as freshwater, brackish water or salt water.
