Cathodic Protection

2.1 Sacrificial Anode Cathodic Protection

Sacrificial anode cathodic protection is a technique used to prevent pipe corrosion by introducing a more reactive metal into the system. The sacrificial metal, typically zinc or magnesium, is connected to the pipe as an anode. When the pipe comes into contact with an electrolyte, such as soil or water, the sacrificial metal corrodes instead of the pipe, thereby protecting it from corrosion.

2.2 Impressed Current Cathodic Protection

Impressed current cathodic protection involves the use of an external power supply to introduce an electrical current into the pipe. This current helps to counteract the corrosive reactions occurring on the pipe’s surface. Impressed current cathodic protection is often used in large infrastructure projects or situations where sacrificial anodes may not be practical.

Corrosion Inhibitors

3.1 Organic Corrosion Inhibitors

Organic corrosion inhibitors are compounds that are added to a pipe’s internal environment to inhibit corrosion. These inhibitors work by forming a protective film on the pipe’s surface, which acts as a barrier against corrosive substances. Organic corrosion inhibitors are often used in water treatment systems and oil refineries to protect pipes against the detrimental effects of corrosion.

3.2 Inorganic Corrosion Inhibitors

Inorganic corrosion inhibitors, such as chromates and molybdates, are chemicals that can be added to a pipe’s internal environment to prevent corrosion. These inhibitors work by forming a protective layer on the pipe’s surface or by interacting with corrosive ions, reducing their ability to attack the pipe material. Inorganic corrosion inhibitors are commonly used in cooling water systems and industrial processes.

Real-Time Monitoring Systems
