Ceramic Nozzles & Tubes
Alumina blast, spray, burner and welding nozzles plus straight and stepped tubes — predictable wear life in abrasive and hot service.
A nozzle is a wear part by definition: it exists to accelerate or shape a stream, and the stream is what wears it out. Alumina nozzles wear evenly and predictably, which lets you schedule replacement instead of reacting to it.
Where it is used
- Sandblasting and shot-blasting nozzles
- Spray nozzles for water, slurry, chemicals and coatings
- Burner nozzles and lances in furnaces and kilns
- Welding and plasma torch nozzles and shields
- Pneumatic injection and conveying nozzles
- Quench and cooling nozzles in heat treatment
Available configurations
| Type | Bore range | Notes |
|---|---|---|
| Straight bore nozzle | Ø1.5 – 60 mm | Blasting, injection, general flow control |
| Tapered / venturi nozzle | Ø3 – 25 mm | Blasting; the venturi reduces wear at the throat |
| Fan and flat spray | by drawing | Cooling, washing, coating |
| Hollow cone and full cone | by drawing | Spray drying, gas scrubbing, cooling towers |
| Straight tube | Ø3 – 80 mm | Furnace tubes, thermocouple protection, sight tubes |
| Stepped and flanged tube | by drawing | Where location and sealing matter |
Threaded metal housings, retaining rings and quick-release holders can be supplied with the ceramic insert where the nozzle is changed frequently.
Grade selection
- Blasting with sharp grit → AL-95, taper bore to reduce throat wear
- Spraying abrasive slurry → AL-99, straight or fan
- Burner and high-temperature duty → AL-99 / 99.7
- Corrosive chemicals, HF or strong alkali → silicon carbide
- Edge chipping at the nozzle tip → ZTA
Wear life and scheduling
Alumina nozzles fail by bore enlargement, not by breaking, so life is predictable: measure the bore when new, measure it at intervals, and replace at your wear limit. Tell us the abrasive and the pressure and we will give you an expected wear rate per hour of operation so you can plan replacement in advance.
