Our proven project process for corrosion protection projects
To ensure that you are fully covered in all challenges relating to the protection of your properties, GCP supports you both in the planning and design of a new system and in situational support in the event of a problem with an existing protected property, as well as in ongoing maintenance and monitoring. Depending on your requirements, we can either provide you with advice, supply you with the necessary components or carry out the installation for you on site. Experience has shown that it is advisable to approach your requirements as follows.
Thanks to its comprehensive expertise, GCP is actively involved in the working committees for the standards.
Rely on over 30 years of experience and innovative solutions for your CP cathodic corrosion protection. As one of the leading CP providers worldwide, GCP German Cathodic Protection is a member of HTG Hafen-Technische-Gesellschaft and is therefore directly involved in the design of the regulations.
Rule out accidents:
Wherever metal surfaces of buildings need to be protected against corrosion, GCP offers you customized CP solutions. Benefit from our extensive experience, from planning and design to the manufacture of individual components and on-site assembly through to long-term monitoring and maintenance. Depending on requirements, we generate the necessary protective current using galvanic processes or impressed current processes for your cathodic corrosion protection.
Questions we are frequently asked about KKS
Corrosion is an oxidation process that always requires a combination of oxygen and moisture. The original principle is the affinity of steel in combination with oxygen to go into a lower energy state and that is corrosion. At the atomic level, the metal reacts to the presence of oxygen and a liquid by releasing electrons, causing it to decompose.
Cathodic corrosion protection works by turning the metal of the protected object into a cathode in the electrical circuit by means of an electrical source. In this way, electrons are supplied to the object to be protected, which are then available at the phase boundary (where the metal comes into contact with oxygen and a liquid) and therefore no electrons can be removed from the atomic structure of the metal. This prevents oxidation and corrosion.
Wherever objects or structures are imbued in Water or Earth, CP can be applied. CP needs a conductive medium to provide the cathode with the electrons needed to prevent oxidation and corrosion.
Typical example for such objects are pipelines for all sorts of mediums, port facilities, tanks and industrial plants, as well as off shore facilities.
The DVGW (German Technical and Scientific Association for Gas and Water) defines a set of regulations that stipulates the requirements and obligations for the protection of buildings. Potential danger to the environment must be averted. For example, KKS is important to ensure the tightness of metal pipelines in order to prevent safety-relevant operating materials from leaking into the groundwater.
Wherever environmental protection or drinking water protection regulations have to be met, cathodic corrosion protection is required by law. This is the only way to prevent corrosion on pipes, pipelines or buildings. This is necessary because damage to passive corrosion protection by a coating either cannot be ruled out or a coating is always abraded, e.g. in rocky or sandy substrates.
The only disadvantage of using PPS is the effort required to plan, build and maintain the PPS system.
The advantages of the KKS system are
Wherever structures need to be protected against corrosion and this cannot be ensured by passive protection such as a coating. The same applies wherever substances that are harmful to the environment or health are stored or transported, e.g. pipelines or tanks.
