  • One of the main reasons for the unlikely
    breakdown in metallic structures is corrosion.
    There are naturally occurring potential
    variations in pipelines if they are unprotected.
    There always flows a current, which leads to
    galvanic corrosion, wherever you go from a minor
    positive to a minor negative.
  • Pipeline cathodic protection is an
    electrochemical process in which, for slowing or
    stopping the corrosion, direct current is applied
    to a metal. Putting cathode protection(CP) on a
    pipeline discharges off of the current of the
    anode and onto the pipeline, hence, prevents
    corrosion from happening, and therefore protects
    the pipeline.

  • Each system component of underground pipeline
    protection or CP has a unique tag that
    determines
  • Anode, reference electrode, rectifier, etc.
  • The quantity of each of the above components
  • The amount of lead wire connected to an identical
    component from the above
  • On each of the components, the tag has to be
    checked, and it has to be ensured that the
    quantity matches the information provided.

The installation process of pipeline cathodic
  • Firstly, for the number of anode rings and their
    spacing, reference electrodes, and the tank
    number, we need to refer to the installation
    drawings/calculation sheets.
  • Next, in the center of the tank, a stake has to
    be placed. The distance from the tank center to
    the first ring has to be measured. Now, using
    chalk or spray paints, we need to mark the anode
    ring location at several places.
  • The individual anode ring segments must be
    removed from the shipping reels, but not with a
    knife or any other sharp object. Every caution
    must be used to avoid any damage to the anodes
    lead wire or its packaging fabric.
  • As determined in the second step, we need to
    place the anode rings. Each anode ring has the
    exact dimensions and includes cable tails that
    can extend up to 6 m beyond the tanks edge.

  • We need to ensure that the labels of each anode
    wire are intact. Next is to move the lead wires
    out of the conduit opening in the ring wall.
  • For the locations where each reference electrode
    has to be installed, we need to refer to the
    datasheet drawings. Next is to install these
    electrodes for which we need to go through the
    electrode packaging.
  • Once we are done with reference electrode
    installation, we need to route the lead cables
    along the same path as of anode lead cables.
  • Lastly, the cable tails have to be taped together
    and supported through the conduit opening in the
    ring wall, so that later they can be terminated
    in the mentioned junction box.
