The fluoroplastic and organic silicon materials selected for the non-metallic rectangular compensator have good high temperature resistance and corrosion resistance, and can compensate in multiple directions, which is much better than the metal compensator that can only compensate in a single direction. It has the characteristics of light body, simple structure and easy installation. Features such as easy maintenance. The fiber fabric and thermal insulation cotton body used in the non-metallic rectangular compensator has the functions of sound absorption and vibration isolation, which can effectively reduce the noise and vibration of boilers, fans and other systems.
Since the main material is fiber fabric, it is weakly transmitted. The use of fiber fabric compensators can simplify the design, avoid the use of large supports, and save a lot of materials and labor. Since system errors are inevitable during the pipeline connection process, fiber compensators can better compensate for installation errors.
Non-metallic rectangular compensators have a relatively complete production and assembly system, and non-metallic expansion joints can ensure no leakage.

Basic structure of non-metallic rectangular compensator
Skin
The skin is a non-metal expansion The main telescopic body of the joint is made of multiple layers of silicone rubber or high-silica polytetrafluoroethylene with excellent performance and alkali-free glass wool. It is a high-strength sealing composite material. Its function is to absorb expansion and prevent air leakage and rainwater leakage.
Stainless steel wire mesh
Stainless steel wire mesh is the lining of the non-metallic expansion joint, which prevents debris in the circulating medium from entering the expansion joint and prevents the thermal insulation material in the expansion joint from escaping outward.
Thermal insulation cotton
Thermal insulation cotton has the dual functions of thermal insulation and air tightness of non-metallic expansion joints. It is composed of glass fiber cloth, high silica cloth and various types of thermal insulation cotton felts. Its length and The width is consistent with the outer skin and has good extensibility and tensile strength.
Thermal insulation filler layer
Thermal insulation filler layer is the main guarantee for the insulation of non-metallic expansion joints. It is composed of multiple layers of ceramic fibers and other high-temperature-resistant materials. Its thickness can be determined according to the temperature of the circulating medium and the thickness of the high-temperature-resistant material. Thermal conductivity, etc. are determined through heat transfer calculations.
Rack
The rack is a profile bracket of non-metallic expansion joints, ensuring sufficient strength and rigidity. The material of the rack should be compatible with the medium temperature. Generally in. Used below. The above is made of stainless steel or heat-resistant steel. The rack generally has a flange surface that matches the connected flue duct.
