ductile iron (DI) reducer is a, durable pipe fitting used to connect pipes of different diameters in water, sewage, and industrial systems. These fittings, typically conforming to ASTM A536 or ISO 2531, are available as concentric (aligned) or eccentric (offset) to manage flow rates and minimize pressure loss.

• Materials & Coatings: Manufactured from ductile iron (often grade 60, 65, or 80) with epoxy coatings for corrosion resistance.
• Types:
  • Concentric Reducers: Conical shape with aligned axes for vertical, liquid-based piping.
  • Eccentric Reducers: Off-center, used in horizontal applications to prevent pocketing.
• Connections: Commonly available as flanged (DI DF) for secure, bolt-on, leak-proof joints or socketed for flexible, push-on connections.
• Size Range: Available for pipe sizes ranging from DN50 up to DN2600.
