Corrosion Resistance Ductile Iron Manhole Cover For Highway
Product Application
Ductile iron round manhole covers are essential components in various infrastructure applications:
  • Road drainage systems: Used for drainage manholes on urban roads, main roads, and highways to ensure smooth water flow while protecting safety.
  • Municipal engineering: Installed at underground pipe network facilities for water supply, drainage, power, gas, and communications.
  • Residential areas: Provides practical and aesthetic coverage for sewers and inspection wells in communities.
  • Landscaping: Maintains drainage systems in parks, squares, and green spaces.
  • Industrial areas: Covers underground equipment wells and pipeline inspection wells in factories.
  • Underground maintenance: Enables easy access for inspection, repair, and maintenance of underground networks.
  • Traffic safety: High-strength design withstands heavy vehicle pressure with anti-slip features for enhanced safety.
Production Process
  1. Raw material preparation:
    • Smelting of high-quality pig iron and scrap steel
    • Spheroidizing treatment with magnesium/rare earth alloys
    • Inoculation treatment to improve casting quality
  2. Modeling stage:
    • Precision mold making from design specifications
    • Sand casting using manual, mechanical, or resin sand molding
  3. Casting and molding:
    • Controlled pouring of spheroidized iron
    • Natural cooling and solidification process
  4. Cleaning and grinding:
    • Mechanical sand removal
    • Precision grinding of surfaces and edges
  5. Heat treatment: Annealing to improve material toughness
  6. Surface treatment:
    • Sandblasting for surface refinement
    • Coating application (asphalt paint, epoxy resin) for corrosion protection
  7. Quality control:
    • Visual inspection for defects
    • Dimensional verification
    • Mechanical performance testing (compression, bending, impact resistance)
  8. Final assembly: Matching covers with rings and packaging
  9. Optional processes: Custom designs or smart sensor integration
