The eccentric reducer rubber expansion joint with a straight lower edge structure completely eliminates
the liquid accumulation dead zone at the concentric reducer, reducing fluid kinetic energy loss. The rubber
layer flexibly extends and contracts under pressure fluctuations, preventing additional pressure loss caused
by vibration in rigid pipe sections.
