Long-line flexible anode for impressed-current cathodic protection
in directional drill applications
Linear anode also called flexible anode , it can be classified into two categories: linear anode based on the nano conductive carbon black composite technology and
linear anode based on MMO/Ti coating. The former is the first generation and the latter are the second
generation. Both of them are used for impressed current cathodic
protection of buried structures, such as buried oil (gas)
pipelines, underground tank, petrochemical container etc. in order
to slow down corrosion. The linear anode is characterized by easy
installation, completed supporting facilities and reasonable price.
The anode to cable connection is made using a copper compression
connector which is sealed using a two part epoxy. Spacing of the
connections will vary depending on the anode used, cable size used
and environment where assembly will be installed.
APPLICATIONS for TELPRO FLEX-ANODE:
- Above and below ground storage tanks.
- Conventional groundbeds.
- Pipelines
- Congested plant areas
