Customer Success Stories
Abu Dhabi National Oil Company (ADNOC)
Challenge: Offshore platform water injection pump impeller failed in 6 months in 25,000ppm chlorine ion media.
Solution: Custom plated 2205 impeller (320mm diameter, 8 blade backward curved design)
Result: 18 months of continuous corrosion-free operation, 9% increase in pump efficiency, $120,000 reduction in annual maintenance costs.
Application scenarios and customer pain point solution
1. Acid medium conveying
Typical scenarios: Sulfuric acid / hydrochloric acid circulation system, refinery acidic water treatment
Solution:
Duplex structure to resist intergranular corrosion, passed ASTM A923 Method A test.
Surface electrolytic polishing (Ra≤0.8μm) to reduce media adhesion.
2. Chloride-containing environment
Typical scenarios: seawater cooling system, chlor-alkali chemical equipment
Solution:
PREN value ≥35, critical crevice corrosion temperature >60℃ (ASTM G48 Method D)
Optional plating reinforcement (HVOF tungsten carbide coating, 4 times higher scour resistance)
3. High temperature and pressure working conditions
Typical scenarios: geothermal fluid transfer, high temperature petrochemical process pumps
Solutions:
Operating temperature range -50°C to 300°C
Finite element analysis (FEA) to optimise blade stress distribution, fatigue life>10^7 cycles
