Customized Impressed Current Cathodic Protection Equipment, also call ICCP.
System Description
Composed of a constant potentiometer (control cabinet), auxiliary anodes with an anode shield layer, reference electrodes, and additional components, the QLYB series ICCP system is designed to protect the hull's underwater areas against corrosion caused by seawater.
Its working mechanism is as follows: the constant potentiometer delivers DC power, with the positive pole connected to the auxiliary anodes and the negative pole linked to the hull.
As seawater completes the electrical circuit, the hull is cathodically polarized. Reference electrodes oversee and regulate the hull potential, keeping it at the proper protective level to resist seawater corrosion effectively.
Adapting automatically to variations in the external conditions surrounding the vessel, the ICCP system adjusts the protective current accordingly, ensuring the hull is consistently maintained within the ideal protective potential range.
Application
This system is applicable to preventing corrosion on the steel surfaces of various ships, offshore platforms, floating docks, and other marine structures. It protects the hull steel from corrosion, particularly after the hull's paint coating has been damaged, and serves as a replacement for the traditional zinc block cathodic protection method.
Types
For the QLYB series ICCP system, the constant potentiometer offers optional current ratings of 50A, 100A, 200A, 300A, 400A, 500A, and 600A to meet specific requirements. The auxiliary anodes, meanwhile, are available in current ratings of 20A, 25A, 50A, 100A, 150A, and 200A for selection.
