Underwater Cutting Lance
Underwater Cutting Lance by TSP delivers oxygen-fed exothermic cutting above 10,000°F with low-amperage ignition and full wet or dry deployment capability.
Key Features:
✔️ Patented alloy-core tubular rod for sustained oxygen-fed exothermic burn
✔️ 12V–14V ignition drawing up to 150A, lower than conventional arc systems
✔️ Self-sustained combustion once oxygen flow is established
✔️ Flex capacity 90°+ without insulation split or flow restriction
✔️ Cuts ferrous, non-ferrous metals, concrete, and rope without preheating
✔️ Tip temperatures exceeding 10,000°F during operation
✔️ Anti-burnback design prevents flame regression into torch body
✔️ Operates in dry and full submersion with no reconfiguration
✔️ Field-proven for naval salvage, offshore platforms, and subsea infrastructure
Underwater Cutting Lance
The Underwater Cutting Lance uses a hollow tubular rod construction with patented alloy core wires running through the centre, through which pressurized oxygen flows to sustain an exothermic reaction once ignition is established. Ignition requires only a single spark from a 12V or 14V automotive or marine battery pack — drawing a maximum of 150 amps, significantly below the 300–500 amps demanded by conventional arc cutting systems. Once ignited, the rod burns continuously without further electrical input as long as oxygen flow is maintained. The rods flex up to 90 degrees or more without splitting the insulation or restricting internal oxygen flow, enabling access to confined or angled cut points.
The lance cuts both ferrous and non-ferrous materials — including cast iron, stainless steel, brass, concrete, and rope — without any preheating or surface preparation. Tip temperatures exceed 10,000°F during active combustion. The patented alloy core wire design and anti-burnback architecture prevent flame regression into the torch body, a critical safety feature during submerged operations. The system operates in both dry and full wet submersion conditions with no modification required between environments.
In large-scale industrial and defense operations, the Underwater Cutting Lance is deployed by naval salvage teams for ship hull sectioning, offshore oil and gas platform repair, underwater pipeline severance, and port clearance following maritime incidents. Commercial diving contractors also use exothermic lance systems for cutting sheet pile during major port infrastructure development and demolition projects.
Tactical Supply Pakistan is Pakistan’s premier source for professional underwater cutting equipment, delivering operationally verified gear to naval commands, commercial diving operators, and industrial rescue teams across the country.
Can the lance rod be safely re-inserted into the torch holder mid-operation if the oxygen supply is briefly interrupted?
Yes, but the rod tip must be fully extinguished before reinsertion. Oxygen interruption stops combustion within seconds. Once confirmed cold, a fresh rod or the remaining stub can be reseated in the holder and reignited with a standard 12V battery spark before resuming the cut.
