THERMOCOUPLE PROTECTION TUBES Clay Bonded SiC In addition to its non-wetting, good thermal shock properties, high abrasion resistance, and good response time. <strong>Pyrotek</strong>’s clay bonded silicon carbide tube can withstand direct flame impingement. Applications • Melting & holding furnaces • Degassing crucibles • Crucible furnaces • Transfer Advantages • Cost effective • Good thermal response • Non-wetting to aluminium and its alloys Alumina Alumina thermocouple tubes are designed for a roof furnace at free air in heat treat, glass and ferrous metal industries. They are not intended for direct immersion to molten metal. Applications • Roof thermocouples • Heat treat furnace thermocouples • Kiln thermocouples • Vacuum furnace application Advantages • High temperature capabilities. Max 3400°F (1870°C) • Moderate cost • Fair resistance to thermal shock • Impervious to gases at high temperatures Mullite Mullite thermocouple tubes are another option for a roof furnace at free air application, with a lower temperature rating than alumina. Applications • Roof thermocouples • Heat treat furnace thermocouples • Kiln thermocouples Advantages • High temperature capabilities. Max 2750°F (1510°C) • Low Cost • Good thermal shock resistance • Impervious to gases at high temperatures MC-1 (aka LT-1) MC-1 thermocouple tubes are specially designed for immersion in molten copper, brass, zinc and lead. They are a unique blend of metal and ceramic. These tubes are also known as LT-1. Applications • Molten copper based alloy immersion • Surfer burner and blast furnaces • Chemical process reactors Advantages • Can be used in oxidizing applications • High temperature capabilities.

TCPT MATRIX *Always consult with a <strong>Pyrotek</strong> sales engineer to properly define the TCPT solution that’s right for your application. *TCPT Type Typical Applications Initial Investment ($$$$ is most expensive) FOR DIRECT IMMERSION TO MOLTEN ALUMINIUM RFM (Reinforced Fiberglass Material). RFM thermocouple tubes are engineered to provide robust, non-wetting to aluminium and its alloys. This fiberglass reinforced material coupled with internal steel tube have the ability to withstand mechanical abuse. This type is also excellent to be used in the zinc industry. Pinnacle. The unique properties of Pinnacle thermocouple tubes provide long-life, nonwetting, and are ideal for foundry and other temperature-sensitive applications. O'-Sialon. O'-Sialon thermocouple tubes are ideally suited for use in the Aluminium industry. They are non-wetting, have high level of oxidation resistance, have high resistance to chemical corrosion, high abrasion resistance and provides excellent thermal response. Cast Iron Plain / Cast Iron Enamel. Both plain and enamel coated cast iron thermocouple tubes can withstand rigors of furnace environment. Their physical strength is ideal for casthouse handling. Ceramic coated tubes provide 25–50% longer life than plain cast iron tubes. Recrystalized SiC. In addition to its non-wetting, good thermal shock properties, high abrasion resistance and good response time. This tube exhibits good oxidation resistance due to its recrystalized microstructure and can be used in many applications. Sialon / SiN. Silicon nitride thermocouple tubes are our highest performance ceramic technology. The superior strength, high thermal conductivity, excellent thermal shock and corrosion resistance contribute to the longest service life in molten application. NOT INTENDED FOR DIRECT IMMERSION TO MOLTEN ALUMINIUM INCONEL 601. Well known and standard material with great resistance to heat and corrosion. This thermocouple tube is not intended for direct immersion to molten metal. Alumina. Alumina thermocouple tubes are designed for roof furnace at free air in heat treat, glass, and ferrous metal industries. It is not intented for direct immersion to molten metal. Mullite. Mullite thermocouple tubes are not intended for direct immersion to molten metal. But it is another option for roof furnace at free air applications with lower temperature rating than alumina tubes. • Crucible Furnaces • Degassing Crucibles • Holding Furnaces • Launder • Melting Furnaces • Degassing Crucibles • Holding Furnaces • Transfer • Reverb Melting Furnaces • Low Pressure Holding Furnaces • Melting Furnaces • Transfer • Launder • Melting Furnaces • Degassing Crucibles • Holding Furnaces • Transfer • Reverb Melting Furnaces • Melting Furnaces • Degassing Crucibles • Holding Furnaces • Transfer • Reverb Melting Furnaces • Low Pressure Holding Furnaces • Melting Furnaces • Transfer • Launder • Open Carbon Bake Furnace: Preheat Section and Pit / Flue firing chambers • Roof Furnace • Heat Treat • Roof Furnace • Heat Treat • Roof Furnace • Heat Treat Relative Mechanical Strength $$$ Refractory with steel pipe reinforced $$$ Refractory with steel pipe reinforced $$$ Strong without pipe fitting $–$$ Cast Iron Strong $$$ Refractory with steel pipe reinforced $$$$ Strongest without pipe fitting $$–$$$ Stainless Steel Strong Relative Typical Life Maximum Working Temperature 3–6 months 1472°F (800°C) 3–6 months 2012°F (1100°C) 2–4 months 2012°F (1100°C) 1–2 weeks 1472°F (800°C) 1–3 months 2732°F (1500°C) 10–13 months 2012°F (1100°C) 7–9 months 2300°F (1260°C) $$$ Alumina Ceramic 3–5 months 2912°F (1600°C) $$$ Mullite Ceramic 3–5 months 2552°F (1400°C) Relative Response Time (#1 fastest) Available Models and Configurations #3 Refer to I5 and I6 series.
