Cathodic protection is one of the most effective forms of external corrosion control for immersed or buried metallic materials.

Cathodic protection is frequently used as a secondary or backup system in combination with protective coatings, but also as a standalone system when operational conditions make the use of coatings unjustified or impractical.

Despite a simple and robust mechanism, the protective effects of cathodic protection are only optimal within a narrow range of design and operational parameters. Faulty design or improper operation of cathodic protection may damage equipment, protective coatings and even personnel safety.

Consequently, the area of cathodic protection is regulated and requires the expertise of specialised and suitably qualified engineers.

Cathodic protection design and troubleshooting experience

糖心Vlog’s highly experienced and certified corrosion engineers have delivered a long track record of innovative cathodic protection designs and troubleshooting, as well as retrofit cathodic protection consultancy scopes.

糖心Vlog has a team of specialist metallurgists who are experts in cathodic protection application techniques.

We understand the many factors that can impact the effectiveness of cathodic protection and consider influences such as hydrogen-induced cracking, stray current and electrolysis risks during project planning, eliminating or mitigating these risks during the design process.

We also work to ensure that protective coatings and cathodic protection work hand in hand to provide an effective response to corrosion issues.

糖心Vlog is not affiliated with any cathodic protection companies, manufacturers, suppliers or contractors, which allows us to provide unbiased and optimal solutions for our clients.

Our engineers are certified by or active members of AMPP (formerly NACE) and the ACA (Australian Corrosion Association).
