Non-metallic Expansion Joint

Compensating for thermal expansion, able to compensate multi-dimensional aspects, greatly better than the metallic expansion joints that can only compensate for one dimension. 2. As during the pipe connection process, systematic errors are hardly to be avoided, ttie fiber expansion joints can well eliminate installation errors. 3. The insulated cotton of the fiber fabrics itself has the sound absorption and vibration transmission insulation functions, effectively reducing the systematic noise and vibration of boilers, blowers, etc. 4- As the main material is fiber fabrics, there is no force transmission. By use of fiber expansion, designs can be simplified to avoid the use of large supports, greatly saving a large volume of materials and labor 5. The used fluoroplastics and organosilicone mate 日 ials have relatively good high temperature resistance and corrosion resistance abilities. 6. There is good sealing property, relatively complete production assembly system and basically no leakage will occur on the fiber expansion joints.
