|The Scorpion™ blue exothermic
cutting lance has many uses in industry for both dry an wet
applications alike. Typical uses include cutting steel bracings
on offshore structures, pipelines, removing jetty and pier
foundations, cutting through concrete caissons, vessels,
propellers and many different types of marine salvage. The lance
will cut through the following materials with ease: plain carbon
& low-alloyed steels, cast irons, stainless steels,
non-ferrous metals, concrete, rock, rope, wood and marine growth.
The process simply requires an industry standard underwater
cutting torch connected to a multistage high flow oxygen
regulator, a DC welding machine and a safety isolation
Should you prefer to cut with power on, the
Scorpion lance should require no more than 150 amps at the tip.
However, the lance will also burn with no electrical power, once
ignited, as long as the oxygen flow is maintained. The lance
burns at approximately 6000 °C (10,000 °F) a temperature
that will melt most materials with ease. The principle of
operation, having ignited the arc is to allow oxygen to flow down
through the centre of the lance. This creates and maintains an
exothermic reaction, which will continue to burn, with or without
the power, until the oxygen flow is stopped.
9.5mm (3/8") x 500mm (20") hollow copper
coated steel tube, having an inner bundle of solid wire segments.
All Scorpion lances are insulated with a ahigh visibility blue
polyolefin tubing for safety. They are supplied in 10kg (22lbs)
boxes, which contains 50 lances.
