Key features of large diameter non-metallic expansion joints include the following aspects:

1. Compensates thermal expansion: Capable of multi-directional compensation, significantly superior to the metallic compensators that can only provide single-directional compensation.

2. Compensates for installation errors; due to inevitable system errors during the pipeline connection process, fiber compensators effectively minimize installation errors.

3. Sound and Vibration Dampening: Fibrous 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. Zero Thrust: Being made of fiber fabric, there is no transmission of force. The use of a fiber compensator can simplify the design, eliminate the need for large supports, and save a significant amount of materials and labor.

5. The materials selected are of better quality.

6. Excellent sealing; features a well-established production and assembly system, ensuring fiber compensators have no leakage.

7. Lightweight, simple structure, easy to install and maintain.

8. Priced lower than metal compensators, with superior quality over imported products. Prices are 1/2 to 1/5 of imported products.
