What is the function of adding a flow guide tube inside the bellows compensator?

The function of adding a metal liner to the inside of a bellows compensator:

The liner serves as a guide for high-velocity flow, reducing wear and tear on the bellows by protecting it from the erosive effects of the medium. This extends the lifespan of the bellows and provides guidance within the compensator.

Additionally, the guide tube’s directional function helps prevent instability in the bellows caused by absorbing deformations in the pipeline, ensuring that the bellows can function normally and reach their expected lifespan.

Bellows compensators, also known as expansion joints or expansion compensators, consist of bellows (an elastic component), end pipes, supports, flanges, guide pipes, and other accessories. They are primarily used in various pipelines to compensate for thermal expansion, mechanical deformation, and absorb axial mechanical vibrations, thereby reducing pipeline deformation stress and increasing pipeline lifespan. The connection methods for bellows compensators include flange connection and welding. Bellows compensators are used to absorb axial displacement.

Different types of bellows compensators compensate for different forms of displacement, including axial, lateral, angular, and combined compensation methods. For bellows compensators that simultaneously experience multiple types of displacement, their various displacements need to be synthesized to calculate the total equivalent axial displacement. Therefore, the nominal displacement measurement of a bellows compensator refers to the measurement of the total equivalent axial displacement.
