Non-metallic compensators (non-metallic expansion joints) skin/strip materials: silicone rubber coated glass fabric, fluororubber coated glass fabric, polytetrafluoroethylene pressed glass fabric,三元乙丙橡胶coated glass fabric, nitrile rubber coated glass fabric, polytetrafluoroethylene film, etc., single or multi-layer composite materials; ceramic fiber fire-resistant fabric, aluminum silicate wool, stainless steel wire fiber fabric, glass fiber fabric, etc.
Non-metallic compensators consist of flexible compensating elements, flanges or headers, thermal insulation materials, and bolts and rods. They provide significant axial, angular, and lateral displacements within a small size range. Their features include zero thrust, with the main material being glass fiber fabric and its coated products, without force transmission. Using non-metallic compensators simplifies design, avoids the need for large supports, and saves substantial materials and labor. They also act as noise and vibration dampers (the fiber fabric and insulation cotton themselves have sound absorption and vibration damping properties, effectively reducing noise and vibration in systems such as boilers and fans). They also have excellent high-temperature resistance, corrosion resistance, and sealing performance, achieved through the coating treatment with high polymers such as silicone and fluorine, offering superior high-temperature resistance, corrosion resistance, and sealing properties. They are easy to install and maintain.

Non-metallic compensator (non-metallic expansion joint) performance features:

Non-metallic compensators consist primarily of flexible compensating elements (non-metallic materials), both-end connecting parts (flanges or pipe ends), adjusting components (threaded rods), and thermal insulation materials. They are mainly used for pipe systems transporting dust, gases, flue gases, coal gas, and other gases to compensate for displacement caused by temperature changes, mechanical vibrations, and foundation settlement.

• Compensation for thermal expansion: Non-metallic compensators (non-metallic expansion joints) can provide greater multi-directional compensation within a smaller size range.

• Compensate for Installation Errors: Due to system errors being inevitable in pipe connections, non-metallic compensators (non-metallic expansion joints) can effectively eliminate installation errors.

• Soundproof and Vibration Isolation: Fiber fabrics and thermal insulation materials inherently possess sound absorption and vibration isolation properties, effectively reducing noise and vibration from systems such as boilers and fans.

• No reverse thrust: As the main material is fibrous fabric, force transmission is minimal. Non-metallic expansion joints can simplify the design.

• Excellent sealing performance: Maintains good sealing under various media. Easy to install and maintain.
