About us

Cathodic Protection and Pin Brazing specialists BAC Corrosion Control Ltd have recently launched ‘STINGER’ – a specially alloyed washer that allows small diameter anode wires to be connected directly to pipelines.

‘STINGER’ has been specifically designed for use with small diameter cables and negates the need of a conventional cable lug and copper sleeve.

The new process, which has a patent pending, consists of a specially alloyed washer which allows the cable to be pushed through a hole in the wall and folded back to allow a standard BAC 8mm direct pin to be used to braze the cable, washer and pin onto the pipe in one process. The piece of cable which is folded back and under the washer, allows the solder to pool underneath ensuring a sound connection.

Previously, when brazing a small diameter cable a conventional BAC cable lug – usually for 10mm2 cable – was used with the addition of a sleeve to fill the gap between cable and lug. The whole lug would then have to be crimped using a compression tool to secure the 3 pieces together. Only then, could the braze be completed. With ‘STINGER’ both time and money are saved as the need for the insert and crimp are now redundant.
