DN1200 Metal High-Temperature & High-Pressure Gas Pipeline Rehabilitation
Location: Qinghe Reclaimed Water Plant, Beijing, China
Asset: DN1200 metallic pipeline
Key Project Parameters & Critical Challenges
- High-temperature, high-pressure corrosive gas transmission pipeline
- Operating pressure: 0.8 MPa continuous working pressure
- Long-term transport of corrosive gas at temperatures above 95°C
- Severe internal wall corrosion and perforations, causing heavy gas leakage
- Demands high-temperature & corrosion-resistant repair solutions to restore structural integrity and airtightness
