The Scorpion Blue exothermic cutting lance has many uses in industry for both dry and 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 and low-alloyed steels, cast irons, stainless steels, non-ferrous metals, concrete, rock, rope, wood and marine growth.
HOW IT WORKS
The process simply requires an industry standard underwater cutting torch (Stinger™) connected to a multistage high flow oxygen regulator, a DC welding machine, and a safety isolation switch (Piranha™) (see separate data sheets for details).
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 power, until the oxygen flow is stopped.
9.5mm (3/8”) x 450mm (18”) hollow copper coated steel tube, having an inner bundle of solid wire segments. All Scorpion lances are insulated with a high visibility blue polyolefin tubing for safety. They are supplied in 9.4kg (20.5lb) boxes, which contain 50 lances.
