LIDAŽ TUBULAR ANODE ASSEMBLIES
| LIDAŽ tubular anodes are assembled as single or multiple anode strings
using a worldwide patented procedure (US patents 4,452,683 and 4,526,666). This system
which is unique in the industry - allows De Nora S.P.A. to custom assemble strings of the
desired length of cable and number of anodes to exactly meet the design requirements. |

PATENTED LIDAŽ Cable-to-Anode Connection:
| Statistical data shows that a large number of system failures are due
to a breakdown of the electrical connection between the cable and anode.
Traditional anodes are connected to the cable with resin based seals; these seals may
develop cracks or lose adhesion to the cable or to the anode, with consequent penetration
of moisture and ultimate corrosion of the electrical contact. |

The LIDAŽ patented connection obtained in the plant by plastic
deformation of the titanium tubes onto the cable eliminates the need for resin based
seals. The sealing actions results from elastic pressure developed by the rubberlike cable
sheathing, allowing a long term service life. |
QUALITY ASSURANCE:
LIDAŽ tubular strings are shop assembled and undergo 100% quality
control testing on all the components as per quality plan of our principals DE NORA S.P.A.
Italy (ISO 9000 certified) before leaving the factory, including:
- electrical and chemical tests on the cable
- helium leak test and pressure test to check each cable-anode seal
- electrical resistance test on the cable-to-anode connection
