Natural gas distribution is made possible
by running pipe to customers. Most of the piping serving customers
is steel and must receive cathodic protection. The gallery of pictures
represented in this demonstration shows the installation of a Replaceable
Deep Anode System being used to provide cathodic protection to
a gas distribution network.
The gas lines to be protected are serving a combination of
commercial and residential customers. The area is congested.
The Right of Way was available, but it was expensive. The surface
soils were sandy and high in resistance.
A decision was made to use a deep groundbed for several reasons.
The need to buy Right of Way was eliminated. Low resistivity
soils were available in deep formations.
A decision was made to use a Replaceable Deep Anode System
for strong economic reasons. The need for protective current
at the site was expected to be much longer that the life of a
deep groundbed. Heavy construction is expensive and made more
expensive by being in a congested area. By designing for replaceability,
the heavy construction expenses were eliminated in the future.
The economy of the design is guaranteed as the additional cost
for a replaceable design was only $621.00. Go to Replaceable
Deep Anode to see a drawing.
Environmental consideration is a factor in all designs. Addressing
environmental concerns is made easy when a casing is used on
a deep groundbed.
The following gallery of pictures shows the successful installation
of a Replaceable Deep Anode System. The installation took only
12 hours. The cost to make the system replaceable was $621.00.
For economy and control, make your next system replaceable.
