Description Our Galvanised Roll Groove Concentric Reducer UL/FM is a high-quality pipe fitting engineered for grooved piping systems, especially in fire protection and sprinkler installations. Made from ductile iron conforming to ASTM A536 Grade 65-45-12, designed to AWWA C606 standards, and finished with hot-dip galvanising for excellent corrosion protection. It carries UL and FM approvals for fire-sprinkler use. Product Overview This concentric reducer provides a secure and efficient way to reduce pipe diameter while maintaining the same centre‐line. With roll-grooved ends, it enables fast installation with grooved couplings, eliminating the need for welding or flange connections in many cases. Ideal for fire-sprinkler, HVAC and water distribution systems. Construction & Design The body is crafted from high-strength ductile iron to ASTM A536 Grade 65-45-12. The roll-grooved ends are manufactured to match standard grooved coupling specifications. The hot-dip galvanised finish ensures durability and corrosion resistance in wet or exposed environments. Approved for working pressures up to approximately 300 psi (≈ 2 100 kPa) depending on size. Key Features and Benefits UL & FM Approved: Certified for fire protection applications, giving you assurance of quality and compliance. Hot-Dip Galvanised Finish: Superior corrosion resistance for long service life in wet or outdoor installations. Roll-Grooved Ends: Quick and efficient installation using grooved couplings — saves labour versus welding or flanging. Concentric Design: Maintains pipe centre-line when reducing diameter, ideal for system alignment and flow continuity. High Pressure Rating: Suitable for use up to ~300 psi (≈2.1 MPa) depending on size — fits many fire-sprinkler and industrial systems. Wide Size Range: Available in various combinations (e.g., 65 × 50 mm, 100 × 80 mm, 150 ×100 mm etc) to fit many pipe transitions. Specifications Material Ductile Iron (ASTM A536 Grade 65-45-12) Finish Hot-Dip Galvanised (to AS4680 / equivalent) Standards & Design AWWA C606 / grooved-end standards Approvals UL Listed & FM Approved for fire-protection use Working Pressure Up to approx. 300 psi (≈2 100 kPa) depending on size Application Grooved piping systems, fire-sprinkler, water, HVAC Applications & Suggested Uses Fire-sprinkler and hydrant piping systems Water distribution and HVAC piping systems using grooved-end technology Industrial process lines where pipe diameter transitions are needed in grooved systems Renovation or retrofit projects where welding is restricted or minimal downtime is required Performance & Maintenance The roll-grooved design allows for fast assembly/disassembly, reduced downtime and lower installation costs compared to welded or flanged transitions. The galvanised finish mitigates corrosion in indoor/outdoor wet systems. For optimal reliability in fire-protection systems, ensure correct coupling alignment and torque the grooved couplings to manufacturer specs. Why Choose Our Grooved Concentric Reducer?
