types of cathodic protection

Cathodic protection  is  the most effective technology to  avoid corrosion  in a  wide  range of  structures,  in particular marine  and underground ones.  At SME Group we are experienced in offering advanced solutions  to protect  pipelines,  systems and marine structures  from  the harmful  effects of corrosion.  There are  different kinds of cathodic protection systems to choose from and all  have their  own  particular advantages  and uses.  Below, we  will  discuss some of the popular systems available  on the market  today.

 

Galvanic cathodic protection is  a commonly employed low-cost and  simple way to protect a pipeline  or  structure from  corrosive attack. That  system involves linking  a more reactive  metal like  zinc  or magnesium with the thing  you  want to protect. Instead  of the structure, the sacrificial  metal erodes,  protecting it against corrosion for years. Galvanic  CP is  frequently found in  underground pipelines,  storage tanks,  and offshore structures. The following details SME Group’s expertise in the design and installation  of galvanic CP systems for long-term protection of vital infrastructure.

 

Impressed Current Cathodic Protection Systems for Corrosion Prevention

ICCP  system  is a more complicatedcathodic  protection system  than  galvanic system  and  is  usually used  forlarge  structures,  like  bridges,  tanks and  ships. The process  is reversed by providing an external  source  of power,  which then  causes the electrical current to  flow  in the  opposite  direction (that of  corrosion). Through  regulating  the level  of current,  impressed  current  cathodic protection  systems  can  provide exact protective  levels on  demand. SME Group  are market  leaders in  the design and  installation  of  impressed  current  cathodic protection systems  for all types of  application to guarantee maximum  corrosion  protection  to our  client's  structures.
