5. Understanding the Importance of Reducers in Piping Systems
Reducers play a key role in ensuring that fluid flows smoothly between pipes of varying sizes. Without reducers, transitioning between different pipe diameters would result in inefficiencies, pressure loss, or even damage to the piping system.
In systems that handle fluids or gases under pressure, such as plumbing or HVAC systems, reducers help maintain the required flow rate and pressure by gradually narrowing or expanding the pipe’s diameter. This ensures the smooth transfer of liquids or gases without causing turbulence or stress on the pipes.
6. How to Choose the Right DN35 to 1-1/2 Reducer
Selecting the appropriate DN35 to 1-1/2 reducer requires careful consideration of several factors, including material compatibility, pressure and temperature ratings, and the type of piping system being used.
