Non-metallic circular compensators are used in boilers, gas turbine exhaust systems, and dust removal systems in thermal power plants. There are also boilers in petrochemical enterprises, flue gas desulfurization devices in industrial furnaces, and dry and wet ventilation ducts. Let's take a look at the advantages and applications of non-metallic expansion joints.
In the pipeline system, if there are thermal stresses caused by temperature changes, local stresses caused by vibrations of equipment and fixed brackets, and stresses caused by system installation deviations at the same time, rigid connections will inevitably cause the pipeline system to deform or be damaged in particularly weak places. If flexible non-metallic expansion joints are used, such damage can be avoided.
This is related to the movement form of non-metallic circular compensators. These movement forms determine the dimensional displacement performance of non-metallic expansion joints. Pressure-bearing single wave bodies 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 needs of expansion difference compensation.
Non-metallic circular compensators have the advantages of universal compensation, large displacement absorption, no elastic reaction force, low external temperature of non-metallic expansion joints, low noise, vibration isolation, easy installation and maintenance, high temperature resistance, corrosion resistance, and wear resistance. They are widely used in circulating fluidized bed boilers. Non-metallic circular compensators have good comprehensive performance, which makes them widely used in many engineering fields.
In the pipeline system, if there are thermal stress caused by temperature changes, local stress caused by vibration of equipment and fixed brackets, and stress caused by system installation deviation at the same time, the use of rigid connection will definitely cause the pipeline system to deform or damage at the weak point, but if a flexible non-metallic circular compensator is used, this damage can be avoided. This is related to the movement form of the non-metallic circular compensator, and the movement form of the non-metallic circular compensator determines the size displacement performance of the non-metallic compensator.
