Axial Multi sphere flexible rubber joint for Noise Reduction with
Custom Bolts and Nuts
Product Description:
Flexible rubber bellow joint consists of outer rubber, inner
rubber, framework layer, and reinforcing bar and flange. Relying on
rubber’s special performances as long range elasticity, air
impermeability, medium, climate and radiation resistance, rubber
expansion couplings can reduce the vibration and noise of pipeline,
and can be caused by the temperature change of heat bilges cold
shrink compensation effect.
Applications:
Liwei provided the drawings required for the expansion double ball
joint, simplifying the customer's installation process. The working
temperature range is -15 ℃ to 80 ℃ (with special variants that can
handle -30 ℃ to 150 ℃), allowing the product to be used in
environments with different thermal conditions. This makes the
double ball flexible rubber joint an excellent choice for heating
and cooling systems, industrial processing plants, water and
wastewater treatment facilities, and many other temperature
fluctuation factors.
