Scheme of Electrochemical Protection of Pipelines and Gas Pipelines with Extended or Distributed Anodes

Corrosion of underground pipelines and protecting from it

Methods of defence of underground metallic pipelines from corrosion are subdivided into passive and active.

Methods of cathode defence of pipelines from corrosion

Installation of cathode defence of pipelines from corrosion

For the corrosion protection of underground pipelines on the route of their bedding the stations of cathode defence are erected (SKZ). The source of direct-current (protective setting), anodic grounding, control and measuring point, leads and cables, enter in the complement of SKZ.

Scheme of Electrochemical Protection of Pipelines and Gas Pipelines with Extended or Distributed Anodes

In a chart with extensive anodes the special anodes of cable type, consisting of metallic explorer (tendons), covered the special electro-conducting shell from elastomera, are used. Most rational is the use of extensive anodes, put on all length of pipeline
