Product Description
Product Overview
The Double Sphere Flexible Rubber Joint is engineered with outer rubber, inner rubber, framework layer, reinforcing bar, and flange components. Utilizing rubber's exceptional properties including long-range elasticity, air impermeability, and resistance to various media, climates, and radiation, these expansion couplings effectively reduce pipeline vibration and noise while compensating for thermal expansion and contraction.
