Water Blast Technology

Contracor offers a wide choice of abrasive blast nozzles made from high-quality tungsten or boron carbide. Various nozzle types and jacket materials are available.

Venturi bore nozzles produce a wide blast pattern and intensify abrasive velocity as much as 100% per given pressure. Venturi nozzles are the best option for increased productivity when blasting larger areas. Long Venturi style nozzles provide approximately a 40% increase in productivity in comparison with straight bore nozzles. Additionally, abrasive consumption can be reduced by about 40%.

The double Venturi style can be regarded as two nozzles in a row with a gap and holes in between to facilitate the entry of atmospheric air into the downward part of the nozzle. The exit segment is also wider than an ordinary nozzle. This modification increases the size of the blast pattern and minimizes a reduction in abrasive velocity.

In the case of rough handling and use of and mineral or coal slag abrasives, tungsten carbide nozzles are the best choice for durability and economy.

Boron carbide nozzles offer long life with optimum air and abrasive use. Boron carbide is best suited for aggressive abrasives such as aluminum oxide and selected mineral aggregates.
