Carbon Steel Pipe Fittings

  • Carbon Steel 45° Elbow (LR/SR) | Butt Weld Fitting for Gradual Pipeline Direction Change
    45° Bend Angle: Gradual direction change — lower pressure drop than 90° elbows.
    Long Radius (LR) or Short Radius (SR): LR (1.5D) standard; SR (1.0D) for tight spaces.
    Seamless or Welded Construction: Seamless for high pressure; welded for large diameters.
    ASTM A234 WPB / WPC: Standard carbon steel material for high temperature service.
    Beveled Ends for Butt Weld: Prepares for easy field welding.
    Full Traceability: Heat number stamped on each fitting.
  • Carbon Steel Concentric Reducer | Symmetrical Taper for Vertical Pipe Size Transition
    Concentric Design: Symmetrical taper — pipe centerline remains straight.
    Vertical Lines Only: Recommended for vertical pipelines or pump suction (flat top eccentric required for horizontal).
    Seamless or Welded: Seamless up to 24″; welded for larger diameters.
    ASTM A234 WPB: Standard carbon steel material.
    Smooth Internal Transition: No sharp edges — minimizes turbulence.
    Beveled Both Ends: Ready for butt welding to larger and smaller pipe.
  • Carbon Steel Bull Plug (Hex Head / Round Head) | Threaded End Closure for Small Bore Lines
    Threaded Connection: NPT or BSP threads — screws into female threaded fitting.
    Hex Head or Round Head: Hex for wrench tightening; round for low torque applications.
    Solid Forged Construction: No porosity — stronger than cast plugs.
    ASTM A105: Forged carbon steel for high pressure service.
    NPT Threads Standard: Tapered threads provide pressure-tight seal with PTFE tape.
    Low Cost: Economical way to close small threaded ports.
     
  • Carbon Steel Cross (4-Way Tee) | Four-Port Butt Weld Fitting for Pipeline Intersections
    Four Openings: Two on run, two on opposite branches — all butt weld connections.
    Equal Cross: All four ports same size (standard).
    Reinforced Intersections: Extra wall thickness at all three branch intersections.
    ASTM A234 WPB: Carbon steel for moderate temperature.
    Seamless up to 12″: Larger sizes fabricated from welded pipe.
    Saves Space: One cross replaces two tees and a spool piece
  • Carbon Steel Reducing Tee | Branch Connection with Smaller Branch Size
    Reducing Tee: Branch opening is smaller than the main run.
    One Fitting Replaces Tee + Reducer: Saves welding and space.
    Butt Weld Connections: Beveled ends on all three ports.
    Reinforced Branch: Extra thickness at the reducing intersection.
    ASTM A234 WPB: Standard carbon steel.
    Any Run/Branch Combination: Custom size reductions available.
  • Carbon Steel Equal Tee | Straight Branch Connection for Same Size Pipelines
    Equal Tee: All three openings are the same size.
    Butt Weld Connections: Beveled ends for welding to main pipe and branch.
    Reinforced Branch: Extra wall thickness at intersection for strength.
    ASTM A234 WPB: Carbon steel for moderate temperature service.
    Seamless up to 24″: One-piece construction for high integrity.
    Full Pressure Rating: Branch rated same as run.
  • Carbon Steel Eccentric Reducer | Offset Taper for Horizontal Pipe Size Transition
    Eccentric Design: Offset taper — top flat or bottom flat installation.
    Flat on Top (FOT): Prevents air pockets in horizontal liquid lines.
    Flat on Bottom (FOB): Prevents sediment accumulation in horizontal solids lines.
    Horizontal Liquid Lines: Standard for pump suction piping.
    ASTM A234 WPB: Carbon steel for moderate temperature.
    Beveled Both Ends: Ready for field butt welding.
  • Carbon Steel Pipe Cap | Butt Weld End Closure for Pipe Termination
    Pipe End Closure: Used to permanently seal the end of a pipe.
    Elliptical or Hemispherical Shape: Elliptical standard; hemispherical for higher pressure.
    Butt Weld Connection: Beveled end for direct welding to pipe.
    ASTM A234 WPB: Standard carbon steel for moderate temperature service.
    Hydrostatic Test Pressure Capable: Designed to full pipe pressure rating.
    Traceable: Heat number stamped on each cap.
  • Carbon Steel 90° Elbow (LR/SR) | Butt Weld Fitting for Standard Pipeline Direction Change
    90° Bend Angle: Standard fitting for turning pipelines at right angles.
    Long Radius (1.5D): Standard for most applications — lower pressure drop.
    Short Radius (1.0D): Compact option for tight spaces (e.g., equipment nozzles).
    Seamless up to 24″: One-piece construction for high integrity.
    Beveled Ends: ASME B16.25 bevel for easy butt welding.
    3D / 5D Bends Available: Long radius bending for large diameter pipelines.
