Nonmetal Expansion joint For thermal power plants: boilers, gas turbine flue gas systems, and dust removal systems. For petrochemical enterprises: boilers, flue gas desulfurization units for industrial furnaces, and dry and wet ventilation ducts. For steel mills: furnaces, converters, and flue gas and dust removal systems. For smelters: air supply and exhaust systems for combustion furnaces and other equipment. For cement plants: kilns, dust removal systems, and flue gas treatment systems. We’ll now introduce its advantages and performance characteristics. Let’s take a closer look at the advantages of non-metallic expansion joints’ structural design.
Advantages and Applications of Nonmetallic Expansion Joints: In piping systems, when thermal stresses caused by temperature changes, local stresses induced by equipment and fixed support vibrations, and stresses resulting from installation deviations all occur simultaneously, rigid connections will inevitably lead to deformation or damage in the system’s most vulnerable areas. By using flexible nonmetallic expansion joints, such damage can be effectively avoided. This is closely related to the movement modes of nonmetallic expansion joints. These movement modes determine the nonmetallic expansion joint’s performance in terms of dimensional displacement. Pressure-bearing single-wave bellows and bellows compensators play an irreplaceable role in certain special operating conditions. For example, circulating fluidized bed boilers require absorbing large thermal expansion differences and torsional deflection angles within very compact spaces; metal expansion joints can no longer meet the demands for compensating these thermal expansions. Nonmetallic expansion joints offer universal compensation capabilities, large displacement absorption, zero elastic reaction forces, and are made of nonmetallic materials. Expansion joint With advantages such as low external temperature, low noise, vibration isolation, easy installation and maintenance, high-temperature resistance, corrosion resistance, and wear resistance, it is widely used in circulating fluidized bed boilers.
Nonmetal Expansion joint Its excellent overall performance has enabled it to be widely used in numerous engineering fields. In piping systems, if thermal stresses caused by temperature changes, local stresses induced by equipment and fixed support vibrations, and stresses resulting from installation deviations all occur simultaneously, rigid connections will inevitably lead to deformation or damage at the system’s weak points. However, by using flexible non-metallic expansion joints, such damage can be avoided. This is closely related to the movement mode of non-metallic expansion joints—their movement mode determines their dimensional displacement performance.
