What Are Concentric Swage Nipples?

Concentric Swage Nipples are forged pipe fittings used to reduce the diameter of a pipeline while maintaining a common centerline. Their tapered and symmetrical design ensures smooth flow, minimized turbulence, and high mechanical strength. They are widely used in vertical pipelines and straight-run systems where flow alignment and pressure integrity are critical.
