Ductile Iron Flanged Concentric Reducer China Factory and Suppliers ISO2531 EN545
The ISO2531/EN545/EN598/EN12842 Flanged Concentric Reducer is a high-performance piping component engineered for seamless diameter transition in water supply networks. Manufactured from premium ductile iron, these reducers ensure structural integrity and optimal flow dynamics, meeting the most stringent international standards for pressure and durability.
Designed for longevity and ease of installation, our concentric reducers are ideal for critical infrastructure projects requiring high pressure resistance (PN10 to PN40). With advanced anti-corrosion coatings and precision machining, they provide a leak-proof connection that minimizes maintenance costs and maximizes the lifespan of the entire piping system.

Frequently Asked Questions
ISO 2531 and EN 545 are closely related standards for ductile iron pipes and fittings. While ISO 2531 is an international standard, EN 545 is a European standard; both specify the requirements for materials, dimensions, and pressure testing for water supply networks.
For highly corrosive environments, we recommend Fusion Bonded Epoxy (FBE) or Epoxy Resin Liquid Painting, as they provide a superior chemical barrier compared to standard bitumen painting.
Every concentric reducer undergoes a rigorous hydraulic pressure test according to the specified PN rating (PN10-PN40) to ensure there are no casting defects or leaks before shipment.
Yes, our ductile iron reducers are suitable for both potable water and wastewater networks, provided the appropriate internal lining (like cement lining) is chosen based on the fluid's pH levels.
For custom sizes or large non-stock orders, the manufacturing process—from pattern making to coating—typically takes around 30 to 45 days after payment receipt.
We use bubble film packing to protect the epoxy coating from scratches, followed by secure placement in standard wooden cases or pallets suitable for long-distance sea transportation.
