Products Description
The spool type bellows rubber is a kind of important flexible connecting device used in pipeline system, widely used in chemical industry, construction, petroleum, natural gas, water supply and drainage, heating, ventilation and air-conditioning (HVAC), fire fighting, electric power and other industrial fields. Through the elastic deformation of rubber material, it can effectively absorb the axial, lateral and angular displacements of pipeline caused by temperature change, mechanical vibration or foundation settlement, and at the same time, relieve the stress concentration of pipeline system, reduce the vibration and noise transmission, and prevent the pipeline from rupture or equipment damage.

Performance characteristics
The spool type bellows rubber has excellent physical properties:
The elasticity of the rubber body enables it to absorb axial (tensile/compression), lateral (offset) and angular (torsion) displacements, effectively relieving the pipeline stress concentration due to thermal expansion and contraction, mechanical vibration or foundation settlement, and avoiding pipeline rupture or equipment damage.
