The harbor facilities and structures of port terminals are corroded by water medium and humid atmosphere every day. Therefore, it is necessary to take effective anti-corrosion measures for these structures, and cathodic protection is one of the most effective means to prevent corrosion in underwater area. When using the impressed current cathodic protection system, it is particularly important to prevent the adjacent facilities not included in the cathodic protection from interference corrosion.
High quality insulation coating with high surface resistance can be applied to the protected part adjacent to the unprotected structure to reduce the current flowing through this part, or an adjustable resistor can be connected in series between the protected part and the unprotected part to reduce and control the current flowing to the unprotected structure to avoid interference corrosion.
Another kind of insulation treatment is based on safety considerations. In flammable and explosive areas, it is strictly forbidden to have sparks when the current flows through due to poor electrical contact between the two parts. At this time, an insulating joint should be connected between them. For example, the steel sheath of the oil hose on the oil terminal and the insulating joint on the loading wall.
In order to make the protected structure get enough current and make the current not flow to the surface of other nearby structures, insulation treatment must be carried out to avoid current loss. For example, the joints of submarine pipelines and onshore pipelines are insulated.
