Directionally Peened Elbows



Help reduce stringers and angel-hair when conveying plastics. Internal finish is a directional roughness applied by a proprietary shot peening process. The finish is consistent and covers 100% of the internal surface of the pipe. The impact of the round shot compresses and fows the surface to produce a form of cratered roughness. The resulting dimple serves to disrupt the boundary layer of the flow creating turbulence and the tendency of particles to tumble rather than slide along the wall of the pipe or tubing.

Non – Directional peening is also available
