Cathodic corrosion protection for your gas pipelines

Even small defects in the coating of your gas pipelines can result in considerable corrosion damage. With our cathodic corrosion protection, you actively prevent corrosion of your gas pipelines and maintain the value of your pipleines longterm. You also significantly reduce your maintenance works on the network.

Cathodic corrosion protection is an effective and widely used procedure in which the rate of corrosion on underground, metal objects is reduced to a minimum by using direct current. terranets bw has been operating corrosion protection equipment since 1967. Using modern data transmission technology, we can quickly and reliably detect impairments and install corrosion protection systems more efficiently. 

Benefit from our extensive experience – we offer an advisory service that is independent of manufacturers. We can draw up a non-binding concept that is individually tailored to your network.
