6. PIN BRAZING CONSUMABLES
Easybond MKII consumables are available as direct pins for attachment of pin brazing cable
lugs and threaded pins
of
various sizes. All Easybond MKII pins have a fuse wire.
BRAZING PINS
Brazing pins are available in direct connection or threaded formats of various sizes. The pins
must be kept dry, stored in delivery tins and care must be taken not to mix different part
numbers.
CABLE LUGS
BAC cable lugs are specially manufactured in the intended material for pin brazing. The lugs are
made in three different types. M1 is pin brazed to the cable. M2 is crimped to the cable and the
“stinger” is pin brazed with the cable. The “stinger” permanently connects anode wires with a
small diameter to pipes utilising the unique silver alloy BAC pin brazing method, without the use
of cable lugs, crimping or old exothermic reactions. The lugs must be kept dry, stored in delivery
tins and care must be taken not to mix different part numbers.
Always use BAC approved crimping methods to ensure adequate contact.
CERAMIC FERRULES
A new ferrule must always be employed in pin brazing (the ferrule must be changed after each
brazing operation). The purpose of the ferrule is to prevent splattering of the molten solder, to
prevent oxidation of the molten solder, and to protect the operator against radiation from the arc.
The ferrule must be kept dry, stored in delivery tins and care must be taken not to mix different
part numbers.
REDUCING SLEEVES
Sleeves are manufactured to allow smaller cables to be crimped into larger than usual lugs. The
cable is inserted into the sleeve, then the sleeve and cable are inserted into the lug. All three
items are then crimped together.
If you are offered any pin brazing consumables from sources other than
from BAC directly or a local BAC appointed Distributor/Agent then we
strongly advise that you do not use those consumables with BAC pin
brazing equipment to avoid any serious risk to people, pipelines and BAC pin brazing
equipment. If in doubt contact BAC.
All BAC products are manufactured to the highest standards under our ISO 9001:2008
procedures. If the use of non BAC pin brazing products and consumables is evident then
warranties will be void. All BAC pin brazing supplies now carry the following notice:
