Pipe Fittings

  • Ductile Iron Flanged Elbow (90° / 45°) | Corrosion Resistant Fitting for Water & Sewage Pipelines
    Flanged Both Ends: Direct bolt-up to flanged valves, pumps, or pipe spools.
    90° or 45° Available: Standard bending angles for pipeline direction changes.
    Ductile Iron Body: QT450-10 / GJS-500-7 high strength, impact resistant.
    Epoxy Coated Inside & Out: 250μm fusion bonded epoxy — WRAS/NSF certified.
    Long Radius or Short Radius: Choose based on space and flow requirements.
    Custom Drilling: Flanges drilled to ANSI, EN, BS, JIS, or AS standards.
  • Ductile Iron Flanged Reducer (Concentric / Eccentric) | Smooth Transition Between Pipe Sizes
    Concentric or Eccentric: Concentric for vertical lines; eccentric for horizontal (flat on top or bottom).
    Flanged Both Ends: Direct connection to different sized flanged equipment.
    Ductile Iron Body: High strength, impact resistant — will not crack like gray iron.
    Smooth Internal Transition: No sharp edges — minimizes turbulence and pressure loss.
    Epoxy Coated: 250μm fusion bonded epoxy for corrosion protection.
    Custom Sizes: Any inlet/outlet diameter combination available.
  • Ductile Iron Flanged Tee (Equal / Reducing) | Branch Connection for Flanged Pipelines
    Equal or Reducing Tee: Equal (same size all ports) or reducing (branch smaller than run).
    Flanged All Ends: Three integral flanges — bolt directly to pipe, valves, or fittings.
    Ductile Iron Body: QT450-10 with epoxy coating — corrosion resistant.
    Reinforced Branch: Extra wall thickness at branch intersection for strength.
    Full Pressure Rating: Rated PN10/PN16 throughout all ports.
    Custom Drilling: Flanges can be drilled to any international standard.
  • Ductile Iron Flanged Cross (4-Way Tee) | Four-Port Connection for Flanged Pipeline Systems
    Four Flanged Ports: One run + two branches + opposite branch — total 4 connections.
    Equal Cross: All four ports same size — symmetrical.
    Reducing Cross Options: Branches smaller than run — available on request.
    Ductile Iron Body: High strength, epoxy coated for corrosion resistance.
    Reinforced Intersections: Extra wall thickness at all branch intersections.
    Full Pressure Rating: Rated PN10/PN16/Class 150 at all four ports.
  • Ductile Iron Socket Elbow (Push-On / Tyton Joint) | Fast Installation for Buried Pipelines
    Socket / Push-On Ends: Tyton or push-on rubber gasket joints — no bolting required.
    90° or 45°: Standard angles for buried pipeline direction changes.
    Integral EPDM Gasket: Factory installed rubber gasket in each socket.
    Quick Joint Assembly: Simply push plain end pipe into socket — installs in 2 minutes.
    Ductile Iron Body: ISO 2531 compliant — high strength for buried service.
    Cement Mortar Lined: Internal lining protects against corrosion and maintains water quality.
  • Ductile Iron Socket Tee (Push-On) | Branch Connection for Buried Push-On Pipelines
    Socket Branch & Run Ends: All three ends are Tyton/push-on sockets — simple installation.
    Integral EPDM Gaskets: Factory installed in each socket — no separate gaskets needed.
    Equal or Reducing Tee: Branch can be same size or smaller than the run.
    Cement Mortar Lined: Standard internal lining for potable water.
    Allows Joint Deflection: Up to 3°-5° angular movement at each joint.
    Ductile Iron Body: High strength, impact resistant — withstands ground settlement.
  • Ductile Iron Double Socket Tee (All Socket) | Three Push-On Connections for Buried Pipelines
    All Three Ends are Sockets: Run and branch all use push-on (Tyton) joints — easiest installation.
    No Flanges, No Bolts: Simple push-on assembly — no bolting or gaskets required.
    Integral EPDM Gaskets: Factory installed rubber gaskets in each socket.
    Ductile Iron Body: ISO 2531 compliant — for buried water and sewer lines.
    Cement Mortar Lined: Standard internal lining for potable water.
    Allows Angular Deflection: Each socket joint allows 3°-5° movement.
  • Ductile Iron 90° Duckbill Check Valve (Tide Flex Valve) | Backflow Prevention for Outfall Lines
    90° Duckbill Shape: Horizontally oriented rubber sleeve with 90° outlet — directs flow downward.
    No Moving Parts: Pure rubber construction — nothing to jam, rust, or freeze.
    Tight Seal at Zero Pressure: Rubber lips close under backpressure — zero reverse leakage.
    Ductile Iron Flanged Body: Bolt-on body with rubber duckbill insert.
    Ideal for Tidal Outfalls: Prevents seawater intrusion into storm or sewer lines.
    Maintenance Free: No springs, hinges, or floats to service.
  • Ductile Iron Flanged Pipe Spool | Custom Length Connector for Flanged Systems
    Flanged Both Ends: Integrally cast flanges or welded-on flanges — your choice.
    Custom Length: Any length from DN50 to DN4000+ mm — manufactured to your dimension.
    Ductile Iron Pipe Body: Class K9 or K12 ductile iron pipe — high strength.
    Epoxy Lined & Coated: Cement mortar lining or epoxy lining available.
    Drilled to Any Standard: ANSI, EN, BS, JIS, or custom bolt pattern.
    Short Lead Time: Standard lengths shipped in 15 days; custom lengths 25 days.
