Rubber expansion bellows basic usages: to compensate the expansion and contraction of the pipeline due to temperature changes and other reasons, but also to compensate the radial displacement of the pipeline, and reduce the vibration propagation in the pipeline system.Mainly used for very small bending radius, or irregular turning, expansion, or absorption of the thermal deformation of the pipe, or not easy to use fixed elbow installation occasions to do pipe and pipe connection, or pipe and equipment connection.
1. Compensation absorption pipeline axial, transverse and angular thermal deformation.
2. Absorb equipment vibration to reduce the influence of equipment vibration on the pipeline.
3. Absorb the deformation amount of the pipeline caused by earthquake and sinkhole. A pressure-measuring elastic element in a pressure measuring instrument.It is a cylindrical thin-walled corrugated shell with multiple transverse ripples.
The bellows are elastic and can produce displacement under the action of pressure, axial force, transverse force or bending moment.
