Exhaust Insulation Blanket

Product catalog summary

Quick Engineering Summary:

Thermal performance is influenced by insulation core material, thickness, exhaust geometry, and outer cover.
Key specifications include continuous operating temperature, target surface temperature, and available installation space.
Begin by selecting the insulation core material, then adjust thickness to meet thermal requirements.

1. Typical Operating Conditions:

Continuous Exhaust Temperature: 500°C – 1000°C
Peak Temperature: Up to 1200°C
Thermal Cycling: Frequent
Vibration Level: Medium to High
Maintenance Access: Often required

2. Insulation Core Materials:

Fiberglass: Continuous Temp ≤ 550°C; cost-effective for moderate temperature systems.
Basalt Fiber: Continuous Temp ≤ 750°C; higher temperature capability and abrasion resistance.
Silica Fiber (High SiO₂): Continuous Temp ≤ 1000°C; flexible and suitable for high vibration environments.
Ceramic Fiber: Continuous Temp ≤ 1260°C; excellent thermal stability for turbo and industrial exhaust.
High-Silica Aerogel Composite: Continuous Temp ≤ 650–800°C; low thermal conductivity for space-limited designs.

3. Surface Temperature Reduction Reference:

Based on a typical uninsulated exhaust surface temperature of 600°C. Actual results depend on various factors such as pipe OD, airflow, and fastening tightness. Options with a 0.1 mm embossed aluminum heat shield liner can further reduce outer surface temperature.

High-Silica Aerogel Composite + 0.1 mm Embossed Aluminum Heat Shield (liner)	20 mm	600°C	80–130°C

4. Engineering Selection Notes:

Select insulation material based on continuous temperature rather than peak temperature.
Increase thickness to achieve lower target surface temperature.
Ceramic or high-silica insulation is recommended for turbochargers.
Choose outer cover based on abrasion, oil, and environmental exposure.

Catalog excerpts

Technical Overview & Engineering Reference This document provides engineering-oriented reference data and selection guidance for removable exhaust insulation blankets used on high-temperature exhaust components. • Thermal performance depends on insulation core material, thickness, exhaust geometry, and outer cover. • Specify continuous operating temperature, target surface temperature, and available installation space. • Select insulation core material first, then adjust thickness to meet thermal requirements. Reference basis: typical uninsulated exhaust surface temperature of 600°C under steady-state operation. Values below are engineering reference ranges for comparison. Actual results depend on pipe OD, airflow, clearance, fastening tightness, and duty cycle. Options with a 0.1 mm embossed aluminum heat shield liner typically reduce outer surface temperature further by improving radiant heat reflection at the hot face.
