Butt-weld elbow

Butt-weld elbows are welded fittings used to change the direction of a pipeline. Their strength and tightness make them the choice for systems with high pressure, high temperature or corrosion risk.

Design

  • Elbows are usually made in 90°, 45° or 180°.
  • Available seamless or welded.
  • Joined to the pipeline by butt welding.

Advantages

  • High mechanical strength: suitable for pressure and vibration.
  • Leak-tight joint: welding keeps the leakage risk low.
  • Long-lasting: resistant to wear and corrosion (depending on material).
  • Standards: manufactured to international standards such as ASME B16.9 and DIN 2605.

Considerations

  • Weld quality must be verified with NDT (radiography, dye penetrant).
  • Orientation and slope must match the system design.
  • Check material certificates and compliance with the standard.
  • Minimise corrosion risk through material selection and external coatings.
Elbow typeDescriptionApplication
Long radius (LR)Lower resistance, smoother flowLarge-diameter lines, process systems
Short radius (SR)Suits tight spaces, may cause higher resistanceSpace-restricted systems
180° return bend (U-type)Reverses the line direction, typically in special processesSteam and cooling lines
