Cathodic Protection Services

Our Cathodic Protection Systems and Services are a proven and reliable method of achieving corrosion control of metals and alloys. Corrosion is a progressively destructive and often potentially hazardous process. Often challenging to identify until well advanced, corrosion is frequently identified when it is too late. Identifying corrosion on submerged or buried equipment and structures is even more critical, which makes Cathodic Protection (CP) so important particularly in the oil & gas, power generation, and petrochemical industries.

Often working in conjunction with protective coatings or vapor phase corrosion inhibitors (VpCI), Cathodic Protection Systems are a proven, highly reliable way of controlling corrosion. The method was initially developed to be used in the shipping industry, but today it is used across all industries where safety, environmental protection, and the long-life is paramount.
