Cathodic Protection Accessories

Splicing Kit

Specification
Description
Cable splicing kits are manufactured from durable plastic suitable for either 2 or 3-way cable splicing of low current (LV) cables. These splice kits protect the cable joint from moisture ingress. Splice kits have proven to be very strong in many environmental conditions. They are moisture-resistant for above or below-ground applications. They are used in cathodic protection systems to protect the cable joints.

Cock Breeze Backfill

Specification
Description

Coke breeze is a carbon backfill which is used around impressed current anodes for underground cathodic protection applications. It is used to:

• Reduce the resistivity of the environment surrounding the anode to increase the amount of current the anode can discharge

• Extend the anode surface area, thus increasing the amount of current the anode can discharge

• Reduce consumption of the anode since the carbon becomes part of the anode consumed before the anode itself.

Particle size and shape are also important when specifying a backfill. Both parameters determine the contact area between anode and ground while influencing the porosity of the column, which is important for gas ventilation. A general-purpose coke breeze is for use in shallow horizontal and vertical groundbeds. For closed deep well groundbed, a special calcined petroleum coke breeze is used.

Handy Cap & Primer

Specification
Description
Handy Cap is the complete weld connection sealer. It is designed to fit any welded connection and is installed simply by pressing firmly into place. A strong wire connection to the structure is important for all cathodic protection systems. A properly sealed weld connection will last for many years, PETUNIA supplies easy-to-use Handy caps, primer & related tapes.

Wrapping Tape

Specification

Description

Vinyl tapes are commonly used to repair or seal aboveground cathodic protection, they are also employed over buried wire splices as a secondary cover. They can be stretched easily and are resistant to UV rays. Rubber and mastic tape is thick and extremely moisture resistant.

Exothermic Welding System

Specification
Description
Thermite welding is a simple, inexpensive, and efficient method of attaching a copper conductor cable to steel or cast iron. It is particularly useful for connecting cathodic protection cables to pipelines including test leads, and negative and bonding cables. The welding process uses a high-temperature reaction charge of powdered copper oxide and aluminum which ignites and produces aluminum oxide and super-heated copper.

Zinc Earthing Cell

Specification
Description

Zinc Earthig Cell consists of two zinc electrodes, insulated from one another. One electrode would typically be connected to the protected structure, the other to an unprotected system. The electrodes are surrounded by low-resistivity backfill allowing large stray currents to pass between them. This enables the structure to be earthed on the ground.
