Reliable Strength
When constructing or modifying water mains, structural integrity is essential. Our ductile iron double flanged 90 degree short radius bends provide a stable, rigid directional change with a compact profile to smoothly redirect pipeline flow within tight spaces and restricted chamber layouts. Engineered to handle high pressure, thermal expansion, and ground movement without fracturing.
Unlike standard cast iron, ductile iron incorporates nodular graphite, giving the metal higher tensile strength and flexibility. This prevents failures and ensures your pipeline infrastructure remains secure.
Corrosion Resistant
To withstand continuous exposure to potable water and aggressive soil conditions, these fittings are treated with a 250 micron fusion bonded epoxy coating. This blue coating provides:
A barrier against rust and chemical degradation
A smooth internal surface finish that lowers friction losses and reduces pumping costs
Total compliance with drinking water hygiene standards
Industry Standard
Every double flanged 90 degree short radius bend in our stock is engineered to meet manufacturing benchmarks, ensuring trouble free drop in replacement or integration into existing networks:
EN 545 Compliance: Guarantees suitability and safety for ductile iron pipelines carrying drinking water
ISO 2531 Standard: Validates the pressure capabilities, dimensions, and tolerances of the castings
ISO 7005-2 Flanges: Standardised PN16 bolt hole configurations for an aligned, leak free seal alongside matching valves, pumps, and pipes

While we maintain good stock levels of standard DN80 to DN300 PN16 flanged fittings at our Suffolk warehouse, we regularly source specialised dimensions, non standard branch reductions, or alternative pressure ratings (such as PN10 or PN25) for major infrastructure projects.
If you cannot find the precise specification required for your project design, contact our technical sales team on 01284 658770 or email your schedule to us for a competitive quote.
