Compensation for thermal expansion: It can compensate in multiple directions, which is much better than metal compensators that can only compensate in one direction. , Compensate installation errors. Since system errors are inevitable during the pipeline connection process, fiber compensators can better eliminate installation errors.
Noise reduction and vibration isolation: Fiber fabrics and thermal insulation cotton have the functions of sound absorption and vibration isolation, which can effectively reduce the noise and vibration of boilers, fans and other systems.
. No reverse thrust: Since the main material is fiber fabric, it is weakly transmitted. The use of fiber compensators can simplify the design, avoid the use of large supports, and save a lot of materials and labor.
, Good high temperature resistance and corrosion resistance The selected fluoroplastic and organic silicon materials have good high temperature resistance and corrosion resistance.
, light body, simple structure, easy installation and maintenance.
Comprehensive performance of non-metallic compensator:
Good overall performance. making it widely used in many engineering fields. Working pressure pipes and equipment usually use non-metallic compensators.
In the pipeline system, if there are thermal stress caused by temperature changes, local stress caused by equipment vibration and fixed support, and stress caused by system installation deviation, the use of rigid connection will inevitably cause the pipeline system to Deformation or damage occurs at the weakest point. If a flexible non-metal compensator is used, this damage can be avoided. This is related to the unique movement form of non-metallic compensators. These forms of motion determine the multi-dimensional displacement performance of the non-metallic compensator.
Pressure-bearing single-wave body and multi-wave body compensators play an irreplaceable role under certain special working conditions. The electronic measuring scale used in the desulfurization powder spraying system of a steel plant originally used metal compensators to compensate the equipment and pipelines. Due to the large reverse thrust, the electronic scale was debugged inaccurately and could not return to zero and weigh correctly. This kind of compensator with rectangular diameter and large displacement can only meet the usage requirements by using non-metallic materials. Through special structural design and material design, it meets the working conditions requirements.
