Product Description

ASTM water heater anode rod

 

Role of the sacrificial anode rod

 

The anode rod is the most important factor in determining the working life of your water heater.

An anode rod is a steel core wire surrounded with one of three different metals.

These metals include aluminum, magnesium, and zinc.

The rod is screwed into the top of your water heater and protects your water heater from rusting.

When the tank is filled with water the anode rod sacrifices itself to protect the exposed steel of the water heater, through a method called electrolysis. Electrolysis happens when there are two pieces of metal connected inside of water, the process makes the anode rod corrode in place of the exposed steel in your water heater. During this process the more noble (less reactive) metal will corrode over the less (more reactive) noble metal. Aluminum, magnesium, and zinc are all much less noble than steel, meaning they will corrode before the steel, which is why they are used for anode rods.

 

Application of our magmesium anode rod:

 

Water Heater,Water container,Pre-polarization of steel structure in seawater,Gas pipe,Anticorrosion of steel and iron structure where high resistant and electrolyte(soil and water) existed.
