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
