Non-metallic compensators are also known as non-metallic flexible compensators, non-metallic expansion joints, non-metallic expansion joints, and fabric compensators.The product can compensate for the axial, transverse, and angular displacement of the pipeline, and has the characteristics of no thrust, simplified bearing design, corrosion resistance, high temperature resistance, anechoic and shock absorption. It is especially suitable for hot air pipelines and soot pipelines.

Non-metallic flexible compensators are widely used in steel mills, smelters, petrochemical plants, thermal power plants, cement plants and atomic energy power plants.Non-metallic compensators are usually used for ventilation, dust removal and exhaust pipes and equipment with low working pressure at the entrances and exits of smoke exhaust and desulfurization, dust removal equipment, air heating, flow-assisted blast and other equipment.

In the piping system, if there is simultaneously thermal stress caused by temperature changes, local stress caused by equipment vibration and fixed support, and stress caused by system installation deviations, the use of hard connection method will inevitably lead to deformation or damage of the piping system at the weakest point.And if a flexible non-metallic compensator is used, this kind of damage can be avoided.This is related to the unique form of movement of non-metallic compensators.These forms of motion determine the multi-dimensional displacement performance of the non-metallic compensator.The elastic elements that make up the working body of the flexible non-metallic compensator are non-metal materials, usually fibrous fabrics, so they are also called fabric compensators (expansion joints, expansion joints).Use of flexible non-metallic compensator: It can compensate for multi-dimensional direction.Various forms, large amount of compensation, long life; can effectively compensate or eliminate installation errors; low stiffness, small elastic reaction force; high applicable temperature range, good corrosion resistance; can effectively isolate vibration and reduce noise and so on.
