Heater & Riser Tubes
International Syalons manufacture a range of advanced ceramic sialon immersion heater and riser tubes for use in the aluminium and non–ferrous molten metal handling industries. Sialon foundry products offer offer long life, improved process reliability and are cost effective compared to competitive 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 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/riser tubes available is very diverse, although we are limited to a maximum outside diameter of 200mm and maximum length of 1500mm. A selection of the tubes we currently manufacture are shown in the tables below. Other tubes can be manufactured to customer requirements. Integral flanges can be made up to 30mm greater than the tube outside diameter.
