Welded reducing straight stainless steel pipe fittings

The 316L butt-weld concentric reducer—also known as a concentric reducing fitting—is a type of butt-weld pipe fitting machined from ultra-low carbon 316L stainless steel. It is designed for the coaxial transition between two pipe sections of different diameters, facilitating a smooth change in the internal flow path. Featuring beveled ends for direct welding to the pipeline, it ensures a streamlined flow that minimizes turbulence and pressure loss; it is widely used in process piping and high-purity fluid systems for the transport of liquids, gases, and other media.
