Abrasive cutting

Powerful cutting jet

Abrasive cutting is a term used when UHP water at 2500-3000bar is mixed with fine abrasive to form a powerful cutting jet able to cut through steel & concrete centimetres thick.
The water jet travels at 500-600m/sec, carrying the abrasive which cuts the material.

Within the cutting nozzle assembly, the velocity of the water jet creates a venturi effect which draws in fine, dry abrasive which is metered from a nearby hopper. As there is virtually no heat or spark generation, this process is also referred to as Cold Cutting & is commonly used in hazardous areas such as in refineries or on offshore platforms.

The abrasive nozzle attaches to a manipulator which is generally attached to the steel surface being cut with magnets. The nozzle is then moved with a hydraulic or pneumatic motor at a controlled speed depending on the thickness of the material being cut.

Benefits of Water Jetting

  • Extreme accuracy of cut without any heat affected zone
  • Leaves a machined like finish
  • Edges can be bevelled for weld preparation
  • Will cut virtually any material
  • Can be used in hazardous/ explosive areas
  • Eliminates the need for plant shutdown
  • Even suitable for decommissioning of munitions
  • The process keeps the operator away from the cutting process
  • Environmentally friendly, does not create any smoke or fumes
  • The water jet is non-contact & therefore does not become blunt nor snags
  • The pump is versatile & can be used for other cleaning & cutting applications
