ANSI/AWWA C207-07 stainless steel flanges are specialized forged flanges engineered for water supply facilities, compliant with American National Standards Institute (ANSI) and American Water Works Association (AWWA) specifications. Key specifications and details are as follows:
- Size Range: NPS 4 – NPS 144 (Nominal Pipe Size, equivalent to DN100 – DN3600; 100mm – 3600mm) – covering small to extra-large diameter pipeline requirements for water supply systems.
- Pressure Class: Class 150, Class 300 (in accordance with ANSI/AWWA C207-07 pressure rating standards, adapted to low-to-medium pressure water transmission and distribution systems).
- Material Scope: Stainless steel (e.g., 304L, 316L – meeting NSF/ANSI 61 drinking water safety standards), carbon steel, alloy steel (forged to comply with AWWA C207-07 material requirements, ensuring non-toxicity, corrosion resistance, and compatibility with potable water and municipal water media).
- Core Advantages: Forged microstructure delivers high structural integrity, reliable sealing performance (prevents water leakage), corrosion resistance to chlorinated water/groundwater, and compliance with drinking water safety standards (lead-free, non-toxic); extra-large diameter design (up to NPS 144/3600mm) adapts to municipal water main pipelines and large-scale water supply facilities.
- Application Scope: Exclusively designed for water supply systems, including municipal drinking water transmission, industrial water supply pipelines, water treatment plant facilities, and large-scale water distribution networks requiring standardized, safe, and durable flange connections.
