Non-metallic flexible expansion joints are widely used in many industries. In addition to considering good compensation ability, the key to choose the right type of non-metallic flexible expansion joints is rotating compensator. We need to consider the application of expansion joints in order to select the correct type, so the negligence of any link will lead to the reduction of life or even failure of the compensator.

Non-metallic Flexible Expansion Joint

Non-metallic flexible expansion joint is used to connect equipment. Its function is to compensate the thermal expansion of the pipeline between 20,000 equipment, reduce the force of installation error on equipment, and facilitate installation. Expansion energy-saving makes the equipment not affected by the blind plate force produced by internal pressure, improves the mechanical condition of the equipment, and makes the equipment easy to fix. Expansion joint is used as soft joint for pump in inlet and outlet pipelines. The universal expansion joint installed on the inlet and outlet pipelines of the pump compensates the thermal expansion of the pipeline, reduces the thrust of the thermal expansion of the pipeline on the pump, or absorbs the vibration caused by the operation of the pump.

Restricted by various aspects is quite complex, but any complex pipeline system can choose several fixing brackets to choose different settings in different parts, which can be divided into several relatively simple single sections, Z-shaped sections and -shaped sections, and the deformation and compensation of each section can be determined separately. Due to the variety of expansion joints, the correct selection is made. The type of expansion joint is very important, so in the overall design of the pipeline system, the direction of the pipeline and the design of the support system (including fixed pipe rack, guide sliding pipe rack, etc.) should be fully taken into account, and the shape and configuration of expansion joint should be considered comprehensively, so as to achieve a safe, reasonable, applicable and economical * combination.

Therefore, the safety and reliability of expansion joints can be greatly improved by correctly selecting the type and structure of expansion joints, reasonably utilizing waveform parameters and fatigue life, and ensuring installation quality. The expansion joints of different specifications are selected according to different application environments, so the application and selection of expansion joints are inseparable.
