Diameter/Material/Year
DN500/Cast Iron/ 1995
Check length
187 meters
Key Findings
Corrosion at 18 locations, sedimentation at 6, scaling at 2, obstructions at 2; no leaks detected
Detection Suggestions:
Damage Severity: Moderate. Recommended follow-up in 3-5 years, with cleaning and maintenance of the sediment section.
Project Overview
The pipeline network is generally operational, but surface corrosion and localized sedimentation are evident. Approximately 5m of sediment has accumulated at the 182m mark, which may affect downstream valves and secondary water supply equipment. Cleaning and maintenance are recommended.
