Structure Features
The main features of the fiber expansion joints as follows:
1. Compensation for thermal expansion, can compensate for the multi-dimensional direction,much better than the one-dimensional only compensation of metal expansion joints;
2. The system error is inevitable in the process of pipe connections, fiber expansion energy can eliminate installation error better;
3. Fiber fabrics,heat insulation cotton has a sound absorption, isolating vibration transmission function itself,it can reduce noise and vibration effectively of boilers, fans and other systems;
4. The main material is the fabric,inability to transfer, fiber expansion joint simplify the design to avoid the use of large bearings,save a lot of materials and labor;
5. The materials of fluoride, silicone materials with good high temperature and corrosion resistance;
6. Good sealing performance,perfect production equipment system, fiber expansion joint is almost no leakage. ? Structure of Code
