The 3M™ Heavy Duty Roto Peen (HDRP) Flap Assembly effectively cleans and descales both steel and concrete.

Peening is a technique for imparting a residual compressive stress into the surface of metals. Having the shot used to peen metal surfaces in a captive flap, allows for more control and greater access to areas that require this strengthening procedure.
Designed for Better Control We engineered our 3M™ Heavy Duty Roto Peen Flap Assembly by adhering tungsten carbide shots to peening rivets, which are attached to heavy-duty flaps. During conventional sandblasting methods, material is released through the air to strike and impact the substrate. However, our tungsten carbide shots remain adhered to the flaps throughout the peening process, giving the operator total control over the peened area. As the wheel rotates, the shots on each flap repeatedly hit the substrate to remove scale, old coatings and surface contaminants. Peening is a cold working process for metal, in which repeated stress applied to the material's surface strengthens the material through compression. The peening method improves the part’s ability to resist fatigue, fracture and stress corrosion cracking. The(more...)
