Saint Gobain Silicon Carbide Tubes for Incinerators

Product Details

Saint-Gobain's N-Durance® silicon carbide (SiC) tubes are nitride-bonded silicon carbide (NB SiC) products designed for high-performance applications in harsh environments like incinerators. Below is a detailed overview of their properties, applications, and benefits specifically for incinerator use, based on available information.Key Properties of N-Durance® Silicon Carbide Tubes-N-Durance® is a fine-grained, nitride-bonded SiC material, consisting of 70-72% SiC and 24-25% silicon nitride (Si₃N₄). It is produced via slip casting or pressing and fired in a nitrogen atmosphere.Maximum Service Temperature: Up to 1,450°C, suitable for the high-temperature conditions in incinerators.Thermal Conductivity: Approximately 20 W/m·K at 1,000°C, ensuring efficient heat transfer in heat exchanger or burner applications.Mechanical Strength:  Cold Modulus of Rupture (at room temperature): >150 MPa (typical 160 MPa).  Porosity:   - Apparent Porosity: <12% (typical 8%).  - Surface Porosity: <1% (typical 0.5%), minimizing contamination and corrosion. Does not contaminate non-ferrous melts (unlike cast iron tubes) and resists chemical attack from incinerator environments (e.g., sulfur, chlorides, ash).Applications in Incinerators- **Thermocouple Protection Tubes**: N-Durance® NB SiC tubes are an economical choice for protecting thermocouple sensors in incinerators, ensuring precise and reliable temperature measurement. They are particularly suited for petrochemical incinerators and waste-to-energy systems.Heat Exchanger Tubes: Used in waste incineration systems to recover energy from high-temperature exhaust gases, leveraging high thermal conductivity and corrosion resistance.N-Durance® is often preferred for its balance of cost, performance, and versatility in incinerator applications.-Innovative Growth Enterprises: Represents Saint-Gobain in supplying N-Durance® thermocouple tubes, emphasizing their role in precise temperature measurement.
