How to choose the right ceramic fibre blanket
When purchasing CVSIC ceramic fibre blankets, the key is to match your equipment requirements and budget. Here is our purchasing checklist to help you make a quick decision:
1. Determine the operating temperature
- Requirements: Determine the operating temperature range of the equipment. Standard types are suitable for temperatures below 1100°C, standard and high-purity types for 1260°C, and high-alumina and zirconia-containing types for higher temperatures.
- CVSIC recommendation: For furnaces with significant temperature fluctuations, choose CV1400 or CV1430 for superior thermal shock resistance. For aerospace or new energy projects, we recommend CV1600, which can withstand temperatures up to 1600°C!
2. Select the appropriate density
- Requirements: Density affects insulation and weight. 64-96 kg/m³ is lightweight and easy to install, 140-160 kg/m³ provides stronger insulation, and CV1600 can reach 170 kg/m³.
- CVSIC recommendation: For petrochemical cracking furnaces, choose 140–160 kg/m³; for residential fireplaces, 96 kg/m³ is sufficient. Our engineers can help you optimise your selection!
3. Determine thickness
- Requirements: Thickness ranges from 6–50 mm; thicker options provide better insulation but are slightly more expensive.
- CVSIC Recommendation: For high-temperature furnaces, select 25–50 mm; for low-temperature pipelines, use 6–13 mm. Precise calculations are required; contact CVSIC for free thickness recommendations!
