Chemical & Petrochemical Shot Peening Successes
Shot peening equipment that handles chemicals can prevent stress corrosion cracking due to exposure to the chemicals. Extended life in components and systems handling the chemicals benefit from surface technology improvements.
- Fabrication of Chemical Handling Equipment
- Fatigue of Offshore Steel Structures
Metal Finishing & Miscellaneous Shot Peening Successes
Certain metals benefit from surface technology succes by shot peening. Therefore components made of those metals are able to withstand fatigue, corrosion cracking, and a variety of other failure mechanisms.
- AI 7050-T7651 High Strength Aluminum
- High Density Powder Metal Gears
- Anodized Aluminum Rings
- Sulfide Stress Cracking
Shot Peening & Modifying Finish Successes
When surfaces of production or transporting equipment are treated with shot peening, there is a phsyical change that results in a benefit to that production or transportation. An example of such surface technology success is a lower coefficient of sliding friction.
- Food Industry Cheese Molds
- Pneumatic Conveyor Tubing
Turbomachinery & Power Generation Successes
The dovetail root of turbomachinery blades is subject to fretting, shot peening is used to prevent fretting failures by treating the surfaces of the blades. Shot peening application allows for greater product resiliency and lifespan.
- Feedwater Heaters
- Diaphragm Couplings
- Turbine Blades & Buckets
