In urban networks, ground movement can cause angular deviations and separation between pipe ends, particularly in large-diameter ductile iron pipelines. In Freginals, this situation affected a DN600 line connected to a steel wall penetration, where a NEO+ 625–650 coupling restored the connection with proper tightness and the ability to absorb future movements.
