Product Introduction:
Material are hard alloy (tungsten carbide), and can meet the needs of various well conditions., with advantages of high hardness, wear resistance, corrosion resistance.

Material: YG8, YG10, YG11, YG12, etc.

Size: According to customer requirements. Customized sizes.

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

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.
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.
