// Why Power Plants Choose Leeho
Composite expertise
built for 24/7 generation
Power plants run hot, wet, acidic, and salty, a punishing environment for steel. Leeho Vina has spent over four decades engineering filament-wound and hand-laid FRP/GRP equipment that outlasts every conventional alternative. Our composite absorber towers, ducting, slurry tanks, and seawater piping are operating across thermal, gas, and combined-cycle sites in Korea and Vietnam.
Every project is engineered to ASTM D3299, D3982, BS 4994, JIS K7012, and KEPCO ES specifications, with full third-party witnessed QA and traceable raw material certification. Our Phu Tho facility delivers components from 50 mm fittings to 5.0 m diameter absorbers. Leeho's largest filament-wound vessel to date measured DN 2500 × 23 m H, supplied to POSCO POSLX in 2023.
