Where use concentric reducer in piping system?

Concentric reducers are used in piping systems to connect pipes of different diameters, ensuring a smooth transition in flow direction. They are typically installed in vertical piping applications, such as in HVAC systems or water supply lines, where maintaining a consistent flow rate and minimizing turbulence is essential. Their design helps to prevent pressure drops and reduce the risk of cavitation in the system. Additionally, concentric reducers are often favored in applications where space constraints require a compact and efficient piping configuration.
