Aluminum alloy sacrificial anode anti-corrosion

The Aluminum alloy sacrificial anode anti-corrosion is easily affected by the chemical composition of the alloy, and we can also provide different alloy composition to meet the anti-corrosion requirements of aluminum alloy sacrificial anode. And we can also manufacture aluminum alloy sacrificial anodes with special chemical composition according to customers' requirements. At present, it is widely used in the anti-corrosion of ship pressure tank, seawater pipeline and port facilities, offshore engineering and drilling platform, condenser and soil medium pipeline.

Aluminum alloy sacrificial anode anti-corrosion is known as the main anti-corrosion method. With the rapid development of economic environment and industrial production, the actual demand for this kind of anti-corrosion products in the industry is also increasing. Generally, aluminum alloy sacrificial anode can prevent the corrosion of steel structure in water consumption and fresh water, and is widely used in port facilities, marine engineering and seawater pipeline, hull and pressurized water tank, storage tank and drilling platform.

In the seawater environment, most metal equipment or the cathodic protection of the bottom plate of crude oil tank can not be in the soil environment with low chloride content. The electrode potential of aluminum sacrificial anode is -1.05 volts. When the surrounding temperature is higher than 49 ℃, the capacitance of sacrificial anode decreases with the increase of temperature. In salt water environment, the current capacity of aluminum sacrificial anode may be reduced by half. Aluminum sacrificial anode can be directly fixed with the equipment structure that needs to be protected without other materials as filler.
