Ceramic fiber pipe covers is made of refractory fiber materials with standard thickness. It is made of refractory fiber and bond with low content of organic bond. With different refractory fiber, abio-bond and organic bond and mixing according to different scales, we can manufacture various fiber pipe which can be applicable for different temperatures. In some thermal equipments, there will be smoke generated when the bond in fiber pipe is burnt and the smoke will be disperses soon.

Product Characteristics

1. Excellent pressure resistance & long service life

2. Low thermal storage & low thermal conductivity

3. Non-crisp material ,excellent tensile

4. Accurate geometrical size & excellent level

5. Cut different angles & convenient construction

6. Excellent wind corrosion resistance

7. Continuous production, well-distributed fibers & excellent stability.
