LIDA® SOIL APPLICATIONS
| SURFACE GROUNDBED: Tubular LIDA® assemblies
are istalled in:
- Shallow vertical groundbeds
- horizontal groundbeds
|
LIDA® anodes are installed for cross
country pipeline cathodic protection.
|
|
CANISTERED ANODES are also an economical and
practical alternative for shallow vertical and horizontal groundbeds. |
| DEEP GROUNDBEDS: Tubular LIDA® assemblies are
installed in deep groundbed. |

Lida® Anodes halt corrosion on offshore
structures (Platfors, sealines, well casings)

LIDA® OFFSHORE AND MARINE APPLICATIONS: Cathodic
protection with impressed current in sea water is used where, for technical or economic
reasons, this method is more convenient than with sacrificial anodes. This is the case,
for instance, for coastal structures such as piers, harbor installations, and platforms
where protection with sacrificial anodes requires an unacceptable weight of anodic
material, and in the retrofitting of all structures in deep waters where the replacement
of sacrificial anodes poses economic and technical problems, LIDA® anodes can be used to
great advantage in the protection of the above mentioned structures. Typical
configurations are:
TENSIONED STRING: More Than 65,000 Amperes installed
worldwide: This consists of one or more tensioned supporting ropes, which serve
as a mechanical support to the anode cable and LIDA® tubular anodes.
|
| PILE MOUNTED ANODES: LIDA® tubular, rod or
plate anodes can be assembled onto support of plastic material and used as pile mounted
anodes. Double armoured cable is available. |

LIDA: INDUSTRIAL APPLICATIONS
A variety of different metallic structures can be cathodically protected such as
chemical and petrochemical plants, refineries, storage tank farms, and power stations. In
a power station, for example, cathodic protection is required for cooling water intakes,
screening equipment, cooling water pumps, condenser water boxes, pipe networks, and oil
storage tanks. Each one of these metallic structures requires proper cathodic protection
designed to meet protective current requirements and current distribution.
The most pertinent qualities required of the anode material for such uses are the
capability to operate at different current densities and the availability of different
shapes to fit various geometric requirements. LIDA® rods are used for the protection of
condenser water boxes and internal surfaces of pipes. LIDA® wires and strips are used in
protecting screening equipment and water intake structures.
Canistered anodes are commonly installed for the protection of external tank bottoms and
LIDA® anode strings are vertically suspended inside tanks for internal cathodic
protection. |
