Boron carbide nozzle,sand blasting nozzle

We supply sandblast nozzles with regular types of straight bore and venture bore,such as boron carbide nozzles,silicon carbide nozzles,tungsten carbide nozzles and ceramic ones. Estimated service life of nozzles(In hours) Nozzle Material Steel Grit/Shot Sand Aluminum Oxide Alumina 20-40 10-30 1-4 Tungsten Carbide 500-8-- 300-400 20-40 Silicon Carbide 600-1000 400-600 50-100 Boron Carbide 1500-2500 750-1500 200-1000 For Boron carbide sand blasting nozzles, they have a service life 4-7times of sintered tungsten carbide nozzles, but their shock resistance is not as that of sintered carbide nozzles, so are suitable to serve under wear, stable atmospheric pressure and medium shock. And tungsten carbide nozzles are suitable to serve under shock circumstance.We are able to produce tubes with diameter of 200mm and length of 300mm, for rings, size can be diameter up to 320mm and length to be 200mm.We will give you prompt quotation against your specified inquiry or drawings.
