Reduced Flanged Tee PN16 Ductile Iron EN545

  Data Sheet |   Product Range

The reduced flanged tee PN16 is a heavy-duty ductile iron fitting designed for branching pipelines in water supply networks, industrial utility installations, and pressure piping systems. Manufactured from high-grade EN-GJS-500-7 ductile iron in full compliance with EN 545, this component provides exceptional tensile strength, impact resistance, and structural integrity under demanding hydraulic conditions. It enables direct dimensional transitions from main distribution headers to smaller branch lines while maintaining a continuous PN16 pressure rating across all branches.

Corrosion protection is achieved through an electrostatically applied blue epoxy powder coating (RAL 5015) with a minimum layer thickness of 250 µm. This high-integrity protective barrier complies with sanitary requirements and holds WRAS and ACS certifications, ensuring complete safety and water purity when used in potable water conveyance and food-grade industrial utilities. The smooth internal surface finish significantly reduces hydraulic friction, minimizes localized turbulence, and prevents encrustation or mineral deposit formation over decades of operation.

Engineered for seamless integration into flanged ductile iron, steel, and thermoplastic piping assemblies, all connecting flanges conform to the dimensional and drilling standards of EN 1092-2 (PN16). The fitting operates reliably within a working temperature range of 0 to 80 degrees Celsius and withstands dynamic pressure transients and ground movement in both buried and exposed pipeline configurations.
