The "Structural Leg" is formed when material is removed to allow two pipes to enter a structure at relatively the same elevation and different angles.

The web dimension between the hole cutouts, measured along the interior wall, influences the strength of the structure and the ability to create high quality seals around the pipe connections.

The data needed to calculate the Structural Leg are:

  1. Diameter of the structure
  2. Diameter of each hole cutout (always larger than the pipe size)
  3. Angle of each pipe entering the structure

Enter the data into the calculator and click the "Calculate"; button.

For more than two pipes in a structure, repeat the calculation between pairs of adjacent pipes.
