Reasons for choosing cathodic protection

When the metal pipe is buried, some measures are often taken to anti-corrosion the pipe, hoping to extend the service life of the pipe. At present, the commonly used anti-corrosion measures mainly include: brush anti-corrosion paint, cathodic protection, sacrifice anode protection, etc. In fact, in various pipeline anti-corrosion, the use of cathodic protection is very much, but you know why to choose cathodic protection, the reasons for choosing cathodic protection and what are? In this chapter, the staff of Jiaozuo Ladbrokes Light Alloy will give you a detailed analysis of the above problems, hoping to help you have a deeper understanding of the knowledge of cathodic protection!

Reasons for choosing cathodic protection

1: surface is not corroded

The combination of cathodic protection and coating (anticorrosive paint) in the anticorrosion of metal pipes can make the underground or underwater metal structures get the most economical and effective protection. A good coating can protect more than 99% of the outer surface of the structure from corrosion. Normally metal pipes are coated with a protective coating before use in the hope of insulating the metal from the dielectric environment.

2: Affordable

The metal anticorrosion effect of cathodic protection is very strong, and the construction cost only accounts for about 3% of the cost of the protected metal structure, but it can multiply the service life of the metal pipe. Nowadays, cathodic protection technology has been widely recognized by the vast majority of people, and has been widely used in the fields of shipbuilding, Marine engineering, petrochemical, electric power, municipal engineering, etc. Reasons for choosing cathodic protection

3: Advantages of combined use

The coating layer and the cathodic protection technology combined application can be more effective in protecting the metal pipe, cathodic protection besides can effectively prevent corrosion coating lesions, and coating also can reduce the requirement of protection current, make cathodic protection is becoming more cost-effective, cathodic protection or even the only player of pipeline corrosion.
