Double-arch rubber expansion joints have greater mobility and flexibility than single-arch rubber expansion joints.
Made of butyl rubber, ethylene propylene diene monomer (EPDM) rubber or chloroprene rubber,
they can absorb the movement and pressure on the pipeline system, compensate for pipeline misalignment,
and the spherical design can reduce the influence of turbulence, sediment accumulation and thrust pressure
