Aluminum Anode For Water Cooling System

Category

About product

The aluminum anode for a seawater cooling system is a specialized component designed to protect the system from corrosion in the harsh marine environment. Its primary function is to provide cathodic protection, acting as a sacrificial metal to prevent corrosion on important components such as pipes and heat exchangers.

When not connected to any external circuit, the aluminum anode exhibits an open circuit potential ranging from 1.10 to 1.18 volts relative to the standard calomel electrode (V, SCE). This potential measurement indicates the voltage at which the anode operates in isolation.

Once connected to the cooling system and operating under load, the aluminum anode maintains a work potential ranging from 1.05 to 1.12 volts relative to the standard calomel electrode (V, SCE). This work potential ensures that the anode effectively protects the system against corrosion.

Product Detail

On offshore drilling platforms, there are various mechanical equipment such as generators, frequency converters, air compressors, high-pressure mud pumps, brake pads for thrusters, hydraulic units for thrusters, and centralized cooling systems in ship designs. These equipment generate a significant amount of heat during operation and require cooling. The most readily available cooling medium at sea is seawater, which has almost zero cost. Therefore, many mechanical equipment on offshore platforms utilize seawater as a cooling medium for heat exchange to ensure the normal and stable operation of systems and equipment.

However, seawater is neutral, and under normal circumstances, the surface seawater is saturated with air, with aThere are many mechanical equipment on offshore drilling platforms, such as generators, frequency converters, air compressors, high-pressure mud pumps, brake pads for thrusters, hydraulic units for thrusters, and centralized cooling systems in ship designs. These equipment generate a significant amount of heat during operation and require cooling. Seawater, which is readily available at sea, is often used as a cooling medium due to its low cost.

Seawater, being neutral, has a dissolved oxygen content of (5-10) × 10^6, with surface seawater being saturated with air under normal conditions. This indicates that corrosion of surface seawater belongs to oxygen depolarization electrochemical corrosion, with corrosion rate controlled by the diffusion speed of oxygen. On the other hand, seawater lacks the conditions for anodic processes found in atmospheric corrosion, resulting in minimal anode polarization. Therefore, seawater corrosion is considered cathode-controlled. It is highly corrosive and can lead to equipment corrosion. To protect the seawater cooling system, sacrificial aluminum alloy marine anodes are used.
