Butt-weld tee

Butt-weld tees are basic fittings used to split a line into three branches or to create a branch connection. They are used in process lines, at instrument connection points and for system extensions.

Design

  • Equal tee: the branch is the same size as the run.
  • Reducing tee: the branch is smaller than the run.
  • Ends are bevelled for butt welding.

Advantages

  • Makes branching the line easy.
  • The welded design suits high pressures and temperatures.
  • Flexible installation; makes it easy to add measuring, control and drain points to process systems.
  • Manufactured to standards such as ASME B16.9, DIN 2615-1/2 and EN 10253-2.

Considerations

  • Clean the surfaces before welding.
  • Verify weld integrity with NDT (radiography, ultrasonic testing).
  • Choose branch orientation and angle to suit the system.
  • Consider corrosion protection, especially for outdoor systems.
