What is Pipeline Rubber Bellow？

Pipeline Rubber Bellow FAQ | 2022-05-16

Definition of Pipeline Rubber Bellow

Pipeline Rubber Bellows are also called expansion bellows, Flexible joints, and compensators. The rubber bellow of the pipeline can be axially expanded and contracted within a certain range, and can also overcome the offset caused by the connection of the pipeline in different axial directions within a certain angle, which can greatly facilitate the installation and disassembly of the valve pipeline. Free expansion and contraction, once it exceeds its maximum expansion and contraction amount, it will play a limit to ensure the safe operation of the pipeline. Mainly to ensure the safe operation of the pipeline, it has the following functions: compensating and absorbing the axial, lateral and angular thermal deformation of the pipeline; absorbing equipment vibration and reducing the impact of equipment vibration on the pipeline; absorbing the deformation of the pipeline caused by earthquake and subsidence.

Introduction of Pipeline Rubber Bellows

Pipeline Rubber Bellows are generally composed of smooth wave compensation elements with rubber flanges at both ends and metal flanges. Metal flanges often use a loose sleeve structure.
The surface of the waveform compensation element is rubber, and the inner layer is a sandwich layer reinforced by several layers of strong fibers or steel belts (wires). Reinforced fiber or steel belt (Wire) and other reinforcing interlayers extend to the rubber-like flanges at both ends, and there are hard steel wire skeletons in the flanges.

Pipeline Rubber Bellows have large displacement compensation ability, can compensate for axial, lateral and angular displacement, reduce noise, reduce vibration and certain anti-corrosion ability. It has the characteristics of high pressure resistance, good elasticity, large displacement, good vibration absorption and noise reduction, and easy installation. It can be widely used in water supply and drainage, HVAC, fire protection, compressors, papermaking, pharmaceuticals, ships, pumps, fans and other pipelines. system.
