Advantages on Tungsten carbide sand blasting nozzles :
1. very high hardness.
2. stable working effort during blasting.
3. long sizes are accetable.
4. very good prices with quite fast delivery.
5. special sizes with drawing are acceptable.
Grewin supply sandblast nozzles with regular types of straight bore
and venturI bore, such as boron carbide nozzles, silicon carbide
nozzles, tungsten carbide nozzles and ceramic ones.
1. 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.
Specification:
Grind resistant, do not active with acid, low & high
temperature resistance,
The density> =2.46g/cm3;
Hardness> =3500kgf/sqm, bending resistance: ≥ 400Mpa
Melting point: 2450degree
And now boron carbide nozzle is instead of hardness alloy, Tungsten
carbide nozzle, silicon carbide sandblasting nozzle.
The working life of boron carbide nozzle is 500-1000H
The size can be customized as per drawing
2. Sintered tungsten carbide, products including various sand blasting nozzle, high-pressure
water spray nozzle, high-pressure water cutting nozzle, bars,
sheets, sealing rings, punching die blocks, glass cutters, etc.
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.
3. Silicon carbide sand blasting nozzles have middle wear resistance and anti-shock ability compared with
boron carbide and tungsten carbide, and much lighter than tungsten
carbides.
