Why Should You Use Our Shot Peening Finishing Treatment?

Increases fatigue strength of new and damaged parts.
Prevents cracking, fretting, and galling.
Enhances lubricity by creating small pores for lubricants to accumulate.
Creates a uniformly textured, finished surface.
Permits the use of hard steels by reducing brittleness.
Closes surface porosity in coatings.
Allows for substitution of lighter materials without sacrificing strength and durability.
Peen forming capabilities to curve or straighten shafts without creating tensile stress.

Technical Highlights: Useful for Specialized Applications

Flow Treatment of Pipe: used primarily in the transport of polymer pellets in oil & gas.
Peen Forming: used on sheets of metals to form concave, convex, or flat shapes, typically for the aerospace or automobile industries.
Straightening: returns bent shafts back into tolerance, reducing waste or replacement costs.
Search Peening: exposes and eliminates hidden corrosion by shot peening small problem areas.

Flow Treatment of Pipe

Polymer pellets slide against the inside of a smooth pipeline, then melt and form streamers or angel hair. These long polymer fibers will contaminate the pellet flow and clog up the transfer system. When the inside of pipeline is roughened by shot peening, the polymer pellets bounce or roll instead of sliding along the inside of the pipe. The pellets’ contact with the side of the pipe is shortened, preventing the formation of angel hair.

Search Peening

Corrosion is not always visible. Sub-surface corrosion is particularly common in areas directly surrounding metal fasteners, screws, and nails. This application is preferable to many other corrosion removal methods because it strengthens the metal while removing the hidden corrosion in problem areas.
