Specialty Pipe Bends Suppliers in Sri Lanka

Long Radius, Hot Induction, Mitered, Piggable, U & J Bends – Precision-Fabricated to ASME B16.9 Standards

Prime Steel Corporation is a premier supplier of custom buttweld pipe bends, offering a wide range of specialized bending solutions including Long Radius Bends, Hot Induction Bends, Mitered Bends, Piggable Bends, U Bends, and J Bends. We serve critical process industries in Colombo and across Sri Lanka, delivering pipe bends that ensure fluid dynamics, structural integrity, and project-specific functionality. Each bend is crafted using advanced manufacturing techniques like hot induction bending, cold bending, or fabricated welding, depending on application requirements. Whether you need smooth transitions in high-pressure oil lines or tight loop returns in heat exchangers, our customized bends conform to ASME B16.9, MSS SP-75, and project specifications.

Range of Buttweld Bends We Offer:

  • Long Radius Bends (LR):
    • Radius = 1.5D or greater
    • Reduces friction and pressure drop
    • Ideal for critical flow pipelines in oil & gas and water systems
  • Hot Induction Bends:
    • Heat-assisted precision bending using induction coils
    • Suitable for large-diameter pipelines with high wall thickness
    • Minimal wall thinning and accurate radii
  • Mitered Bends:
    • Made by welding two or more pipe segments cut at an angle
    • Cost-effective for large-diameter or low-pressure systems
    • Preferred in HVAC and structural piping systems
  • Piggable Bends:
    • Designed for pipelines that require pigging (internal pipeline cleaning)
    • Smooth inner surface and large radius to allow pig passage
    • Used in oil & gas and chemical pipelines
  • U Bends:
    • 180° bends, mainly used in heat exchangers and condensers
    • Fabricated with tight tolerances for thermal and pressure cycles
    • Available in small diameters for tubing applications
  • J Bends:
    • One side longer than the other, forming a J-shaped loop
    • Used in chemical injection lines, gas skids, and tight installations
    • Custom lengths and angles available upon request
