Double Venturi Boron Carbide Nozzle

Characteristic

The inner core use imported high purity boron carbide raw materials, produce with high-tech equipment and fine process.Nozzle have long service life, high hardness, high strength, high chemical stability, light weight, high temperature resistance, corrosion resistance and other characteristics,which is 3-4 times service life than tungsten carbide nozzle.

The different between single venturi and double venturi nozzle

Single venturi nozzle is the long range type, one air inlet. 

Double venturi belongs to high speed type, with eight holes around the shell, due to the high speed air flow, the speed of air ejecting faster than compressed air, speed of blasting is higher.
