Product Name: Non-metallic Compensator (Non-metallic Expansion Joint) Nominal Bore Size: Circular: 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: Silicon rubber coated glass fabric, Fluororubber coated glass fabric, PTFE coated glass fabric, EPDM coated glass fabric, Nitrile rubber coated glass fabric, PTFE film, and other 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 connections, thermal insulation materials, and bolts with rods, offering significant axial, angular, and lateral displacements within a compact 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 compensators simplifies design, avoids the need for large supports, and saves substantial materials and labor. They also serve as noise and vibration reduction devices (the fiber fabrics and insulation materials themselves have sound-absorbing and vibration-reducing properties, effectively reducing noise and vibration in systems such as boilers and fans). Additionally, they possess excellent high-temperature resistance, corrosion resistance, and sealing properties, achieved through coating with high polymer materials like silicone and fluorine, and 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), adjusting parts (threaded rods), and thermal insulation materials. They are primarily used for displacement compensation in pipeline systems conveying 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) offer significant multidirectional compensation within a smaller size range.

• Compensate for Installation Errors: Due to system errors that are inevitable in pipeline 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, there is no transmission of force. Non-metallic expansion joints can simplify the design.

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