Why can non-metallic compensator be widely used?

Non-metallic compensator is used in thermal power plant:boiler, gas turbine smoke exhaust system, dust removal system. Petrochemical enterprises:boilers, industrial furnace flue gas desulfurization devices, dry and wet ventilation ducts. Iron and steel plants:furnaces, converters and smoke exhaust and dust removal systems. Smelting plants:Combustion furnaces and other gas supply and exhaust systems. Cement plant:Kiln, dust removal, and flue gas treatment system. Let's take a look at the advantages of non-metallic expansion joint structure. Advantages and applications of non-metallic expansion joints:In piping systems where there are simultaneous thermal stresses caused by temperature changes, local stresses caused by vibrations of equipment and fixed supports, and stresses caused by deviations in system installation, rigid connections are bound to lead to deformation or damage in particularly weak areas of the piping system. Such damage can be avoided if flexible non-metallic expansion joints are used. This is related to the form of movement of the non-metallic expansion joint. These forms of motion determine the dimensional displacement performance of the non-metallic expansion joint. Pressure-bearing single wave body and wave body compensators play an irreplaceable role in some special working conditions. For example, circulating fluidized bed boilers need to absorb large expansion differences and torsional deflection angles in a very compact space, and metal expansion joints can no longer meet the demand for expansion difference compensation.
 
Non-metallic compensator has the advantages of universal compensation, large displacement absorption, no elastic reaction force, low external temperature of non-metallic expansion joint, low noise, vibration isolation, easy installation and maintenance, high temperature resistance, corrosion resistance, wear resistance, etc. It is widely used in circulating fluidized bed boilers. Non-metallic expansion joints have good comprehensive performance, which makes them widely used in many engineering fields. In pipeline system, if there is thermal stress caused by temperature change, local stress caused by vibration of equipment and fixed support, stress caused by deviation of system installation at the same time, the use of rigid connection will definitely lead to deformation or damage of pipeline system at the weak point, but if flexible non-metallic compensator is used, such damage can be avoided, which is related to the form of movement of non-metallic compensator, and the movement of non-metallic compensator form determines the dimensional displacement performance of the non-metallic compensator.
