Corrosion of metal underground or aboveground storage tanks is a normal, natural process
that is the result of an electrochemical reaction in which current flows from areas where corrosion
is occurring (anodic areas) to areas where it is not (cathodic areas). A cathodic protection system
reverses the process. R-SS tank ICCP systems have been used to successfully protect crude oil
storage tank, product oil tank, produced water tank and sewage water tanks, etc.

  Tank's Internal Cathodic Protection

Either sacrificial anodes or impressed current anodes (mostly MMO anodes) are used for such system. And the resistivity, pH, temperature, content of tank liquid medium and the details of tank internal coating are the design parameters of cathodic protection.

  Tank's External Cathodic Protection

As the storage tanks are on ground or buried, their external bottom plate (on-ground) or the whole external surface (buried) should be protected against corrosion. For smaller tanks, the sacrificial CP can be applied but for the bigger tanks ICCP is usually installed. There is variety of ICCP anode designs regarding the diameter and accessibility of tank bottom plate contact surface. One common approach is the use of linear anodes in concentric rings.

R-SS design engineers can provide CP reliable proposal based on client's parameters and  complete integrated CP system. Each design is carried out to customer, national and international standards to ensure that you are provided with a cost effective and specialised CP system. Furthermore R-SS
]provides a complete documents of corrosion control specialising
in cathodic protection to ensure safe and continuous plant operation.
