What are the names of non-metallic compensators?

Non-metallic compensator is also called non-metallic expansion joint, fabric compensator, flexible compensator, etc. It is due to its main material of silica gel cloth, asbestos cloth, fiber cloth and other composite materials.
Non-metallic compensator can better muffle sound and vibration isolation, which can effectively reduce the noise and vibration of boilers, fans and other systems.
The main features of the non-metallic compensator are
1. Provide larger directional compensation in a smaller size range.
2. Non-metallic compensator has good resistance to high temperature and corrosion.
3. No force transfer, no special requirements for fixed support and guide support of pipeline, can simplify the design to save a lot of materials.
 
The development and application of non-metallic compensator: non-metallic compensator as a flexible element, with its unique performance. Widely used in mining, metallurgy, electric power, cement building materials, nuclear energy, petrochemical and other industries of fluid transportation pipelines and equipment. Non-metallic compensator is also known as flexible expansion joint, flexible bellows, flexible joints, etc., sometimes also called shock absorbing throat.
 
Non-metallic expansion joint in order to prevent the pipeline from moving up and down after the heat and cold. To set a fixed bracket on the pipeline to ensure that the overall position of the pipeline remains unchanged. On the other hand, the stress generated by the pipeline after heat and cold far exceeds the allowable stress of steel pipes, joints and other fittings, to stop the expansion and contraction of the pipeline, any fixed brackets and structures are powerless, only the selection of appropriate compensation devices to eliminate stress, in order to ensure the operation of the pipeline system. There are two common ways of compensation: natural compensation devices and non-metallic compensators. Pipeline system bending parts of the corner greater than 150. can be done as a natural compensation device, the advantage is simple and reliable; when the use of bending parts of the pipeline can not absorb the deformation of the pipeline, should be set up compensator. Commonly used metal expansion joints are rectangular corrugated expansion joints, casing type compensator and waveform expansion joints.
