| Heated pipe or duct | Steady operation around 150–250°C; occasional start-up or shutdown temperature changes | Continuous service with routine thermal cycling | Reduce heat loss and keep the outer surface within the project’s touch-temperature or personnel-protection limit | Confirm the paper’s rated service temperature, thickness, compression allowance, facing compatibility, and required outer-jacket design. |
| Furnace door or access panel | Steady operation around 300–450°C; brief peaks may be higher | Repeated opening, closing, and temperature cycling | Limit heat leakage through joints and provide a conformable layer for irregular surfaces | Check the actual peak temperature, joint gap, attachment method, edge protection, and whether vibration or repeated handling could damage the paper. |
| Industrial oven or process enclosure | Steady operation around 500–650°C | Long operating periods with controlled process cycles | Meet the required cold-face temperature or heat-loss target within the available installation space | Use the supplier’s thermal-conductivity data at relevant mean temperatures; determine thickness from a heat-transfer calculation rather than a room-temperature value. |
| High-temperature equipment lining | Steady operation around 700–850°C, subject to the material’s verified rating | Potentially continuous service with substantial thermal gradients | Provide a compact insulation layer while maintaining acceptable hot-face and backing temperatures | Obtain written confirmation of continuous and peak-temperature limits, atmosphere compatibility, shrinkage data, and suitability for the specific lining arrangement. |
| Outdoor or humid installation | Process temperature varies by equipment; ambient exposure may include moisture and weather | Thermal cycling combined with possible water exposure | Maintain insulation performance and protect the layer from moisture ingress and mechanical damage | Specify weatherproof cladding and sealed joints. Confirm moisture behavior, drying procedure, and compatibility with any coating or facing. |
| Vibration-prone equipment | Process temperature set by the equipment; vibration occurs during operation | Continuous or intermittent movement, impact, or abrasion | Reduce heat transfer without premature loosening, tearing, or loss of thickness | Check fastening and support details, compression under installation, abrasion protection, and whether a more mechanically robust insulation system is needed. |
