HEATER AND RISER TUBES
Slide 1

International Syalons manufacture a range of sialon and silicon nitride-based advanced ceramic heater and riser tubes for use in the aluminium and non–ferrous molten metal handling industries. Fine silicon nitride and sialon foundry products offer long life, improved process reliability, and are cost effective compared to alternative materials, such as cast iron and refractory ceramics, such as silicon carbide and aluminium titanate. Sialon is an alloy of silicon nitride and combines excellent thermal and mechanical properties.

Syalon 101 has found extensive use in non–ferrous molten metal applications as a result of its high strength, toughness, thermal shock resistance, corrosion resistance and its non–sticking nature in contact with aluminium and its alloys.

Immersion and induction heater tubes are the most effective method of heating the melt in the aluminium processing industry. Syalon 101 tubes offer protection to heating elements due to its excellent physical properties.

The range of heater and riser tubes available is very diverse. A selection of the sialon tubes we currently manufacture are shown in the table below. Other tubes can be manufactured to customer requirements. Please contact us with your enquiry.

For details on using our sialon tubes, please download our User Guide.
