Customer Success Story
Client: 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 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 & Solutions
1. Acid Medium Conveying
Typical scenarios: Sulfuric acid / hydrochloric acid circulation system, refinery acidic water treatment
- 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
- 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 & Pressure Conditions
Typical scenarios: Geothermal fluid transfer, high temperature petrochemical process pumps
- Operating temperature range -50°C to 300°C
- Finite element analysis (FEA) to optimize blade stress distribution, fatigue life >10^7 cycles
