Cathodic Protection Cable Joints

Cathodic protection is a technique that is used to protect a metal structure from corrosion under water by acting like an electrical cathode. A simple method of protection connects the metal to be protected to a more easily corroded “sacrificial metal” to act as the anode.

Thorne & Derrick, a leading distributor for Filoform cable joints, have this week supplied 300 off Filoform CPJ95 Cathodic Protection Joints to the oil and gas industry.

Filoform CPJ cable jointing kits are used on cathodic protection applications including pipelines, tanks and buried structures. The CPJ joints can be supplied with or without brass line taps as standard – this range of cable joints suit mains cable single core maximum size up to 120sqmm and branch single core cables up to 35sqmm.

Two variants of Filoform CP cable joints are offered:

CPJ – The classic cathodic protection joint for use when upright branch joints are required

CB0 – A “Y” shaped joint for horizontal branch jointing applications

Filoform CPJ Cable Joints – Mixing Instructions

Care should be taken by the Jointer to ensure the cable jointing resin is mixed thoroughly and in accordance with the manufacturers guidelines:

1. Remove the aluminium outer bag taking care not to damage the clear inner bag. Immediately use the cable jointing resin after opening the aluminium outer bag

2. Remove the separator from the centre of the resin bag

3. Mix contents by kneading vigorously for at least two minutes. Make certain all the resin cable compound is squeezed from the corners and edges of the bag.

4. Pouring of the resin: Cut a small edge from the bag. Carefully pour the resin into the joint shell. Empty (hardened) resin packs can be disposed as regular waste material.

Attention:

• Do not mix different types or brands of cable resins
• Take steps to prevent damage as a result of spilling resin
• Wear disposable gloves and process only in a well ventilated room
