Galvanized 90° Female Threaded Long Radius Bend

The Galvanized 90° Female Threaded Long Radius Bend is engineered to smoothly redirect fluid flow by 90 degrees while minimizing pressure drop and turbulence across high-flow piping systems. Featuring Female-to-Female (F/F) threaded connections manufactured to BS EN 10242 / ISO 49 standards, this long-radius fitting offers a broader curve and lower friction resistance than a compact 90° Malleable Iron Elbow. Hot-dip galvanized for superior corrosion resistance, it provides decades of reliable, leak-free performance in water supply, HVAC, fire protection, and industrial fluid applications. As a core component of our Galvanized Pipe Fittings lineup, it delivers exceptional structural integrity in demanding environments. Key Features of Galvanized 90° Female Long Bend Hot-Dip Galvanized Protection: Coated with a uniform, heavy-duty zinc layer to prevent rust, oxidation, and chemical corrosion in wet and harsh environments. Low Pressure-Loss Geometry: The extended radius design creates a gentle fluid trajectory, drastically reducing friction, flow noise, and system pressure loss compared to standard tight-radius elbows. Precision Female BSP Threads: Taper and parallel internal threads (BS 21 / ISO 7-1) guarantee a tight, pressure-resistant seal, complementing our full range of BSP Threaded Fittings. High Ductility & Tensile Strength: Made from premium EN-GJMB-350-10 Malleable Iron Pipe Fittings material to absorb mechanical shock, piping vibration, and thermal expansion. 100% Leak Tested: Every single bend undergoes rigorous pneumatic air-tightness testing (minimum 0.5 MPa) prior to packaging.

A: The main difference is the surface finish and application: Galvanized 90° Long Bend: Hot-dip galvanized with a protective zinc coating, making it ideal for drinking water, outdoors, and humid environments. Black 90° Bend: Finished with anti-rust oil, making it suitable for fuel oil, steam, natural gas, or indoor decorative applications. Q2: What is the difference between Fig. 1 and Fig. 2 Long Bends? A: Fig. 1: Features Female x Female (F/F) threads on both ends (double female). Fig. 2: Features Male x Female (M/F) threads (one end male thread, one end female thread). Q3: Why choose a Long Radius Bend instead of a Standard 90° Elbow? A: A long radius bend provides a much smoother curve, which significantly reduces fluid turbulence, friction, and pressure loss across long piping runs. Standard elbows are better suited for tight spaces where compact installation is required. Q4: Are these fittings certified for drinking water applications? A: Yes, our hot-dip galvanizing process complies with international hygiene and material standards, making them fully suitable for potable water distribution systems. Q5: Do you provide OEM branding and customized bulk packaging? A: Yes. As an experienced direct manufacturer, we offer complete OEM/ODM options including custom logo embossing on fitting bodies, customized carton printing, inner plastic bags, and palletizing.
