Non-metallic expansion joint, non-metallic compensator is also known as air duct fabric compensator, non-metallic compensator fabric, etc. Non-metallic compensation apparatus has high temperature resistance, corrosion resistance, noise elimination, etc. It is divided into circular and rectangular. Non-metallic compensator according to the requirement, choose the appropriate base material, proper skeleton materials, advanced design of rubber formula, the reasonable structure of tape, with scientific production process.
Non-metallic compensator can more than compensate displacement direction. A variety of forms, a large quantity, long service life, compensation can effectively compensate or remove the installation error, low rigidity, small elastic reaction, suitable high temperature range, good corrosion resistance, can effectively isolate vibration and reducing noise. Non-metallic compensator is of good performance to make it be widely used in many fields of engineering. Working pressure is not high ventilation, dust smoke extraction and air conditioning heat preservation of pipeline and equipment commonly used compensation device.
In the pipeline system, if exist at the same time the thermal stress caused by temperature change, the equipment vibration and fixed support of local stress and stress of the system installation errors, adopt rigid connection, will inevitably lead to piping systems occur at the weakest point deformation or damage. If using the flexible non-metallic compensator, it can avoid the occurrence of such damage. This related to non-metallic compensator specific forms of exercise. These movements form determines the multidimensional displacement performance of non-metallic compensator. Pressure type single-wave, multiwave compensator is irreplaceable in some special operating conditions. A steel desulfurization powder spraying system with electronic, the original use metal compensator compensation equipment and pipeline, because of reverse thrust is larger, the electronic scale debugging is not accurate, unable to return to zero and accurate weighing. Instead of the rectangular aperture, large displacement of the compensator can only using non-metallic materials can meet the use requirements. By special structure design and material design, meet the requirement of working condition.
Non-metallic compensator is widely used in steel mills, smelting, petroleum, chemical, thermal power plants, cement plants and nuclear power plants, such as exhaust smoke desulfurization, dust removal equipment, air heating, help flow blower equipment out of the entrance, it is much better than metal expansion joints.
