Double Flanged 90ºDuckfoot Bend Ductile Iron Pipe Fittings

At FYL , we understand that a piping system is only as strong as its weakest fitting. The Double Flanged 90ºDuckfoot Bend Ductile Iron Pipe Fittings represent a critical component in modern vertical drainage and industrial riser systems. This specialized fitting combines a 90-degree elbow with an integrally cast support base—the “duckfoot” plate—allowing engineers to anchor heavy risers directly to support piers or walls.

Our Double Flanged 90º Duckfoot Bend Ductile Iron Pipe Fittings eliminate the need for separate brackets or straps, reducing installation time by up to 30%. We manufacture this product using premium ductile iron (GGG50/ISO 1083), ensuring that every Double Flanged 90ºDuckfoot Bend Ductile Iron Pipe Fittings delivers exceptional tensile strength and impact resistance. Whether you are specifying parts for a pharmaceutical clean room or a municipal sewage lift station, FYL provides the reliability your project demands.

Key Technical Features

We design our Double Flanged 90º Duckfoot Bend Ductile Iron Pipe Fittings with a focus on structural integrity and hydraulic efficiency.

Why Our Material Science Matters

Every Double Flanged 90ºDuckfoot Bend Ductile Iron Pipe Fittings from FYL undergoes nodularity verification (minimum 85% spheroidal graphite). This microstructure gives our Double Flanged 90º Duckfoot Bend Ductile Iron Pipe Fittings the ductility to withstand water hammer and ground settlement. You will never find sand holes or shrinkage porosity in our products—we use computer-controlled induction melting and resin sand molding.

Product Applications

We have supplied Double Flanged 90ºDuckfoot Bend Ductile Iron Pipe Fittings to over 200 projects globally. Typical applications include:

• Pharmaceutical & Biotech: Sanitary drainage for WFI (water for injection) systems—smooth bore prevents biofilm.
• Sewage Treatment Plants: Vertical pump column risers and sludge recirculation lines.
• Petrochemical: Acid-resistant coating options for corrosive condensate.
• Water Supply: Air release valve risers on large transmission mains.
• Animal Husbandry: Gravity-fed manure collection systems with high solids content.

Example: A large dairy farm in the Netherlands replaced welded steel bends with our Double Flanged 90º Duckfoot Bend Ductile Iron Pipe Fittings and eliminated three annual shutdowns for weld pitting repair.

Manufacturing & Quality Control (FYL Factory Advantage)

Our factory, established in 2010, operates a dedicated ductile iron pipe fittings production line. Here is how FYL guarantees quality for every Double Flanged 90ºDuckfoot Bend Ductile Iron Pipe Fittings :

• Material Verification: Optical emission spectrometer (OES) analysis per heat.
• Mechanical Testing: Tensile, hardness, and impact tests (ISO 1083).
• Dimensional Inspection: CMM verification of flange drilling, duckfoot base flatness (<0.5mm/m).
• Coating Testing: Holiday spark test (no pinholes), adhesion cross-cut test (Class 1).
• Traceability: Each fitting laser-marked with heat number, DN, and PN rating.

We also offer OEM customization —if your design requires non-standard flange drilling, extended base plates, or special coatings (polyurethane, rubber lining), our technicians will modify the pattern.

Installation Best Practices 

To maximize the service life of your Double Flanged 90ºDuckfoot Bend Ductile Iron Pipe Fittings , follow these guidelines:

1. Concrete Anchor Design: The duckfoot base must be bolted to a cured support pier (minimum 20 MPa concrete). Use non-shrink grout under the base plate.
2. Gasket Selection: Nitrile (NBR) for petroleum environments; EPDM for water/sewage; FPM for high temperature.
3. Bolt Torque: For PN10/16 flanges, tighten M20 bolts to 200–220 Nm using a cross-sequence pattern.
4. Riser Alignment: The vertical flange face must be level within 1mm/m to avoid side-loading the Double Flanged 90º Duckfoot Bend Ductile Iron Pipe Fittings.

FAQ – Frequently Asked Questions

Q1: Can your Double Flanged 90º Duckfoot Bend Ductile Iron Pipe Fittings be used for buried installations?

A: Absolutely. FYL offers heavy-duty epoxy coating (min. 400 microns) plus PE tape wrapping for direct burial. The ductile iron body is inherently corrosion-resistant against soil electrolytes.

Q2: Do you provide custom flange drilling?

A: Yes. While our standard Double Flanged 90º Duckfoot Bend Ductile Iron Pipe Fittings use EN 1092-2, we can machine any drilling pattern (ASME, JIS, KS) with a short lead time.

Q3: How do I verify the authenticity of FYL fittings?

A: Every genuine Double Flanged 90º Duckfoot Bend Ductile Iron Pipe Fittings has a FYL logo, heat number, and DN/PN cast raised. Scan the QR code on our packing list to trace the melt report.

Q4: What is the maximum operating temperature?

A: With standard EPDM gasket, -10°C to +120°C. For high-temperature condensate (up to 200°C), we supply FPM gaskets and a special coating.
