9m Diameter Tunnel Wear-Resistant Coating Protection
Location: Nanhua Reservoir, Taiwan, China
Asset: 9m diameter water conveyance tunnel
Project Objectives & Performance Criteria
- Core Goal: Substrate protection and exceptional wear resistance
- Strict Wear Resistance Standard: Under continuous 240h impact of 30m/s water flow with 17% sand content, thickness loss of 7mm wear-resistant coating shall be limited to ≤30%
- Harsh Service Environment: Long-term high-speed, high-sediment water erosion
- Durable Coating Requirement: Extend tunnel service life and secure structural stability
