There are many types and working parameters of impressed current cathodic protection devices

1. The process of iron rusting can be divided into two categories:

1, chemical corrosion, direct reaction of iron and oxygen at high temperature, get iron oxide. (Less common)

2, electrochemical corrosion (common), divided into two kinds: hydrogen evolution corrosion, affixed in the acidic wet environment of corrosion.

Second,

1. Oxygen inhalation corrosion is the most common in nature.

2. Conditions: impure iron, air, humid environment.

3. The idea is that in humid conditions, impeccable iron (containing carbon) forms a myriad of tiny galvanic cells of iron, oxygen, and water.

4. Iron: negative electrode: Fe-2E -=Fe2+ carbon: positive electrode: 2H2O+O2+ 4E -=4OH-Fe2++2OH-=Fe(OH)24Fe(OH)2+2H2O+O2=4Fe(OH)32Fe(OH)3+ Water loss in air = [Fe2O3·nH2O] (rust) +(3-N)H2O

It can be seen from the above formula that after losing electrons, iron forms rust with oxygen and water and dissolves in water, so that the steel structure will be corroded bit by bit.

Since the positive electrode in the above equation needs to gain electrons to form hydroxide, then we provide electrons to the protective steel structure (negative electrode) by an applied current, so that the iron in the steel structure will not lose electrons and be corrode.

The impressed current of Marine anti-marine biological device is determined according to the length of the pipe and the state of the coating. In general, the longer the distance, the greater the current is required. Usually, the current of 720mm 50km pipe is within 5A, and the MAJORITY of PE coated pipe is 2A protection, and in special cases, there are more than 10A. Impressed current of cathodic protection.
