What is the service temperature limit of refractory fiber insulation?

The service temperature limit of refractory fiber insulation is typically around 1650°C (3000°F). This type of insulation is designed to withstand high temperatures while providing thermal resistance, making it suitable for a variety of high-temperature applications, such as in furnace linings, kilns, and other industrial equipment.

At temperatures approaching or exceeding this limit, the material may begin to degrade or lose its insulating properties, which can compromise the effectiveness of the insulation and potentially lead to safety hazards or efficiency losses in a thermal system. The 1650°C threshold reflects a balance between performance and material integrity, ensuring adequate protection for systems that operate in extreme heat conditions.

The other temperature limits mentioned in the options represent higher classifications of refractory materials, but they are generally not associated with the standard fiber insulation commonly referred to in industrial and engineering contexts. Therefore, the correct recognition of 1650°C as the service temperature limit aligns with its widely accepted classification in industry standards.
