The fluoroplastic and organic silicon materials selected for the non-metallic rectangular compensator have good high temperature resistance and corrosion resistance. They can compensate in multiple directions, which are much better than the metal compensators that can only compensate in a single direction. They are light, simple in structure, and easy to install and maintain. Features. The fiber fabric and thermal insulation cotton body used in the non-metallic rectangular compensator itself 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 has no power to transmit. Using fiber fabric compensators can simplify the design and avoid the use of large supports, saving a lot of material and labor. Since system errors are inevitable during the pipeline connection process, the fiber compensator can better compensate for the installation errors.
The non-metallic rectangular compensator has a relatively complete production and assembly system and the non-metallic expansion joint can ensure no leakage.
Connection method:
①Flange connection type
②Pipe connection type
The basic structure of non-metallic rectangular compensator:
Skin
Skin is not The main telescopic body of the metal expansion joint is a high-strength sealing composite material composed of multiple layers of silicone rubber or high-silica polytetrafluoroethylene with excellent performance and alkali-free glass wool. 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 to prevent debris in the circulating medium from entering the expansion joint and to prevent the thermal insulation material in the expansion joint from escaping outward.
Insulation cotton
Insulation cotton has the dual functions of insulation and air tightness of non-metallic expansion joints. It is composed of glass fiber cloth, high silica cloth and various types of insulation cotton felts. Its length and width are the same as The outer skin uniformly 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 thermal conductivity of the high temperature resistant material. etc. are determined through heat transfer calculations.
Rack
The rack is a contour bracket of non-metallic expansion joints to ensure sufficient strength and rigidity. The material of the rack should be compatible with the medium temperature. Generally in. Use - 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.
