Transporting an entire assembly across the country for specialized surface repair is one of the highest unforeseen expenses in industrial plant maintenance. Flap peening (also known as rotary flap peening) offers a portable, highly controlled alternative that meets FAA and military specifications right on the tarmac or power plant floor.
How Flap Peening Works
Flap peening consists of shot particles bonded to flexible flaps attached to a rotating mandrel. As the tool spins at calibrated RPMs, the shot impacts the surface with consistent force. Operators utilize speed controllers and dedicated Almen fixtures to ensure intensity matches the original blueprint requirement.
Key Operational Advantages
- Zero Disassembly: Treat localized stress concentration points directly in place.
- Precise Geometry Control: Target inner bores, fillets, and welded seams safely.
- Audit-Ready Documentation: Fully compliant with SAE AMS 2590 guidelines.
