The solution is Naopa Supply’s Exothermic Lances

What are Naopa Supply’s Exothermic Lances?
Naopa Supply’s exothermic lances are tubes assembled by electric welding and containing special wire strands inside. Unlike oxygen lance tubes, once lit, fusion lances generate their own ignition, maintaining high temperatures without the need for external catalysts.

The product must be free of oil and grease to avoid explosions that could occur due to the mixture of oxygen and oil.

Naopa Supply’s exothermic lances offer a variety of end finishes, including quick-release couplings, threaded couplings, threaded ends, and plain ends.

Naopa Supply’s melting lances are a reliable and economical means of hot cutting, melting thick foundry waste, and removing the bottoms of pots and pans, as well as for other production needs.

Naopa Supply’s exothermic lances are commonly known as “burning lances.”

Naopa Supply’s exothermic lances can be used for a variety of cutting tasks in the metallurgical industries working with ferrous and non-ferrous materials, for cutting foundry waste, and also in the construction industry for demolition. These exothermic lances are used to cut virtually any type of material quickly and efficiently.

The most common uses of exothermic lances include:

  • Opening and cleaning casting holes
  • Removing slag and steel waste from the bottom of pots and furnaces or scuttles
  • Cutting rolls of any size
  • Cleaning stainless steel casting waste, pipes, tanks, etc.
  • Removing or cutting copper and nickel waste
  • Removing refractory material from pots, furnaces, tundishes, etc.
  • Train derailment
  • Construction projects for cutting reinforced concrete
  • Cutting or drilling concrete or ceramic materials
  • Cutting large bolts or dowels
  • Opening cutting grooves in thick ferrous and non-ferrous materials

Exothermic lances, when used with liquid or gaseous oxygen at a pressure of 100-200 psi, once ignited, react to generate temperatures of over 3800°C. Exothermic lances can be used to cut material as thin as 1 inch or as thick as 6 feet. The life of the exothermic lance depends on the volume of oxygen, its purity, and the operator’s experience.

Common exothermic rod sizes:

  • .625″ OD x 3 meters of smooth-ended tube.
  • .840″ OD x 3 meters of smooth-ended tube.
