Oil & gas combines the toughest constraints: fatigue-corrosion under H2S (sour service), high pressure high temperature (HPHT), long maintenance-free service life on offshore infrastructure. Shot peening, HFMI and cold working significantly improve the performance of critical equipment.

Typical operations
Typical operations
Shot peening on HPHT valves
Valve bodies, seats, stems — targeted peening for H2S fatigue-corrosion improvement.
Cold working on risers and pipelines
Fastener holes, flanges — cold expansion to delay marine fatigue.
HFMI on offshore structures (jackets, FPSO, platforms)
Critical welds — fatigue improvement per NACE MR0175.
Needle peening on internal tube welds
Zones inaccessible to other technologies.
