DN100 Carbon Steel Forged Plate Flange

Our DN100 forged plate flanges are strictly engineered for low-to-medium pressure fluid architectures, including:

Water Treatment & Piping Systems: Ideal for municipal water supply, sewage treatment plants, pumping stations, and industrial filtration networks due to its corrosion-resistant yellow zinc coating.

HVAC & District Heating: Extensively used in commercial and industrial heating, ventilation, and air conditioning piping loops to secure valves and pumps.

Oil, Gas & Petrochemical (Low Pressure): Suitable for non-corrosive hydrocarbon transport, utility lines, and auxiliary process piping in refineries.

Power Generation & Utilities: Utilized in power plant cooling water circuits, low-pressure steam lines, and auxiliary water infrastructure. 

Each DN100 flange undergoes strict inspection procedures:

• Raw material chemical composition testing
• Dimensional accuracy verification
• Pressure resistance evaluation
• Surface defect inspection
• Bore diameter and sealing face inspection
• Final batch inspection before shipment

Manufacturing system certified under ISO 9001 and CE standards. We fully support inspections by SGS, BV, TÜV, or Lloyds according to client requests.
