Non-metallic compensators are widely used in many engineering fields because of their good comprehensive performance. Prudential compensators are commonly used in ventilation, dust removal and smoke exhaust, air conditioning and heat preservation pipelines and equipment with low working pressure.
In pipeline system, if there are simultaneously thermal stress caused by temperature change, local stress caused by vibration of equipment and fixed support, and stress caused by system installation deviation, rigid connection will inevitably lead to deformation or failure of pipeline system at the weakest point. If the flexible non-metal compensator is used, this kind of damage can be avoided. This is related to the unique motion form of non-metal compensators. These motion forms determine the multi-dimensional displacement performance of non-metallic compensators.
The pressure-bearing single-wave body and multi-wave body compensators play an irreplaceable role under some special working conditions. The electronic weighing scale used in the desulfurization and powder injection system of a steel plant used metal compensator to compensate the equipment and pipeline. Because of the large reverse thrust, the electronic weighing scale can not be adjusted accurately, and can not be returned to zero and weighed correctly. The rectangular caliber and large displacement compensator can only be made of non-metallic materials. Through special structure design and material design, the working condition requirements are met.
