Non-metallic expansion joint

Non-metallic expansion joints are composed of flexible compensating elements, flanges or reducers, thermal insulation materials, and bolts and rods, which can provide significant axial, angular, and lateral displacements within a small size range. They feature no thrust, with the main material being glass fiber fabrics and their coated products, without force transmission. The use of non-metallic expansion joints simplifies design, avoids the need for large supports, and saves a significant amount of materials and labor. They also serve as noise and vibration reduction (the fiber fabrics and thermal insulation cotton themselves have sound-absorbing and vibration-reducing properties, effectively reducing noise and vibration in systems like boilers and fans). Additionally, they possess excellent high-temperature resistance, corrosion resistance, and sealing properties, achieved through coating with high molecular materials like silicone and fluorine, ensuring superior high-temperature resistance, corrosion resistance, and sealing performance. They are easy to install and maintain.
Non-metallic expansion joint features:

1. Compensation for thermal expansion: Non-metallic compensators (non-metallic expansion joints) can provide larger multidirectional compensation within a smaller size range.
2. Compensation for Installation Errors: Due to inevitable system errors in pipe connections, non-metallic expansion joints can effectively eliminate installation errors.
3. Noise and Vibration Damping: Fiber fabrics and thermal insulation materials inherently possess sound absorption and vibration isolation properties, effectively reducing noise and vibration in systems such as boilers and fans.
4. No Reverse Thrust: Due to the main material being fiber fabric, there is no transmission of force. Non-metallic expansion joints can simplify the design.
5. Excellent Sealing Performance: Offers good sealing under various media. Easy for installation and maintenance.
