Concentric Swage Nipple
Concentric swage nipple is a type of pipe fitting characterized by a gradual reduction in the diameter of the pipeline, while keeping the central axis of the pipeline unchanged, forming a concentric shape. It plays a role in connecting pipes of different diameters in the pipeline system, enabling smooth fluid transition, reducing resistance and energy loss. We can provide clients with high quality concentric swage nipple. Welcome to your purchase.
