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.
