Product Name: Non-Metallic Compensator (Non-Metallic Expansive Joint) Nominal Diameter: Round: DN200～DN7000 (mm); Rectangular: Any Size Design Pressure: ≤±300 KPa Design Temperature: ≤1300℃ Connection Type: Flange/Welding Compensation Quantity: Axial ±300, Lateral ±200 (mm) Structure Type: External Pressure Edge Type

Non-metallic compensators (non-metallic expansion joints) skin/strip materials: silicone rubber coated glass fabric, fluororubber coated glass fabric, polytetrafluoroethylene film glass fabric,三元乙丙胶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 are composed of flexible compensating elements, flanges or adapters, thermal insulation materials, and bolts with rods, which can provide significant axial, angular, and lateral displacements within a small size range. They feature no thrust and no force transmission. The main material is glass fiber fabric and its coated products. The use of non-metallic compensators simplifies design, avoids the need for large supports, and saves a substantial amount of materials and labor. Additionally, they act as noise and vibration reduction (the fiber fabric and insulation cotton themselves have noise and vibration reduction properties, effectively reducing the noise and vibration of systems like boilers and fans). They also possess excellent high-temperature resistance, corrosion resistance, and sealing properties, achieved through coating with high molecular materials like silicone and fluorine, offering superior high-temperature resistance, corrosion resistance, and sealing performance. They are easy to install and maintain.

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

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

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

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

• Acoustic and Vibration Dampening: Fiber fabrics and thermal insulation cotton inherently have sound absorption and vibration isolation properties, effectively reducing noise and vibration in systems such as boilers and fans.

• Zero reverse thrust: Due to the main material being fiber fabric, there is no transfer of force. Non-metallic expansion joints can simplify the design.

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