DI Double Flanged
Ductile Iron (DI) double flanged pipes are robust, high-strength conduits featuring flanges at both ends for secure, bolted connections in industrial piping, water distribution, and sewage systems. They offer superior durability and are ideal for above-ground installations, bridge crossings, and pump stations where leak-proof, rigid, and occasionally dismantled joints are required
- Structure & Material: Manufactured from ductile iron (spheroid graphite cast iron) with welded or screwed flanges, often complying with standards like BS EN 598 or EN 545.
- Sizes & Pressure: Typically range from DN50 to DN300, though larger sizes exist, with pressure ratings commonly PN10/16.
- Coating & Lining: To prevent corrosion, they are generally epoxy-coated internally and externally, or lined with cement mortar for water/sewage applications.
- Advantages: Strong, durable, corrosion-resistant (with proper coating), and easy to install or disassemble.
- Compliance: Generally conform to international standards such as ISO 2531, BS EN 545 (water), or BS EN 598 (sewage).
