Weld concentric reducers feature a conical shape that tapers to a smaller diameter at one end, forming a seamless transition. These reducers are ideal for vertical flow applications where they provide efficient and reliable performance in fluid management systems.
For horizontal installations, we recommend using eccentric reducers instead, as they prevent fluid accumulation with their flat-sided design. Concentric reducers minimize flow agitation, ensuring smoother transitions in vertical piping systems.
