When a cathodic protection system is applied to a pipeline with spigot and sleeve joints, these joints must be electrically bonded. To attach the electric cable connection over the joints, BAC pin brazing can be used. The brazing pins are brazed at both the spigot and sleeve ends of the pipe and the cable attached.
For pipes of ductile or cast-iron, threaded brazing pins are used. Then a prefabricated cable with nuts is fastened. For steel pipes, either threaded brazing pins with nuts are used, or the cable is brazed directly onto the pipe by means of a lug.
In a cathodic protection system, there are often a great number of connections for anode cables, test posts etc. The BAC pin brazing unit contains all the equipment and tools required to make safe cable connections.
The BAC pin brazing system can also use a welding generator as a power source in situations where a great many connections need to be made in one place such as pipe coating yards, lay barges etc.
