Cathodic corrosion protection

The life and reliability of steel pipelines are influenced to a large extent by corrosion protection measures. We take on the project design, construction, maintenance and evidence for cathodic corrosions protection. Our specialist qualified staff are able to professionally carry out the planning, development and servicing in the light of applicable regulations and laws (GW 12, DIN 30676 or AFK recommendations by the DVGW).
