Passive corrosion protection
Passive corrosion protection, i.e. painting or coating the pipeline, is the first step. However, this alone does not suffice as even small imperfections in the coating soon lead to local corrosion on the pipeline. Achieve a greater degree of safety with active corrosion protection.
Active corrosion protection
Cathodic corrosion protection is the most effective method of stopping electrochemical corrosion processes. A protective current (direct current) prevents current from escaping at the gaps in the coating or sheathing.
The Voltage Controlled Smart Decoupling Device, VCSD, is specially designed for cathodic corrosion protection. It also protects people, devices and components against temporary and stationary overvoltages.
