Products Description
EPDM (Ethylene Propylene Diene Monomer) and NBR (Nitrile Butadiene Rubber) industrial rubber expansion joints for pipe are versatile components widely utilized in various industrial applications to accommodate axial, lateral, and angular movements, as well as to absorb vibration and noise, while providing flexibility and seal integrity. EPDM, known for its excellent weather, ozone, and heat resistance, is suitable for outdoor and high-temperature environments, whereas NBR, distinguished by its oil and solvent resistance, is ideal for applications involving petroleum-based fluids. Rubber expansion joints for pipe integrate reinforced fabric or metal inserts to enhance pressure rating and durability, making them indispensable in pipelines, pump systems, and other critical process equipment where compensation for thermal expansion, settlement, or misalignment is crucial.
