Underwater Cutting Lance 18

Descripción del producto

Xingrui Underwater Cutting Lance has many uses in industry for both dry and wet applications. Typical uses include cutting steel bracing on offshore structures, pipelines, removing tap hole and pierce foundations, cutting through concrete ingots, vessels, propellers and many different types of marine scraps. The lance will easily cut through the following materials:plain carbon & low alloyed steels, cast irons, stainless steels, non-ferrous metals,concrete, rock, rope, wood and marine risers.
  The progress simply requires an industry standard underwater cutting torch connected to a multistage high flow oxygen regulator, a DC welding machine and a safety isolation switch.
  Prepare to cut with power on, the lance should require no more than **0 amps at the tip,however, the lance will also burn with no electric power, once ignited, as long as the oxygen flow is maintained,the lance burns at approximately ***0C (*0, **0F) a temperature that will melt most material easily. The principle of operation,having ignited the arc is to allow oxygen to flow down through the center 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.
  All cutting operations should be conducted using DC (-Ve) polarity. In addition, there must be a positive operating disconnecting switch (also referred to as a knife switch) in the circuit. We recommend our product ***-amp duel pole, certified, isolation switch. This switch shall not be operated unless specifically directed by the diver. When the divers calls for a change the tender must confirm that change to the diver. A procedure shall be developed to check the integrity of the electrical circuit before commencing any cutting operations.
