Pipe Tee Dimensions – Standard Reducing & Equal Tee

Pipe Tee dimensions are covered in ASME B16.9. Refer to the table given below for the size 1/2″ to 48″. In piping two types of the tee are uses. Stright / equal and reducing tee. The following shall be checked during the inspection of Pipe Tee Dimensions.

The diameter of branch and run pipe
The thickness of the tee
Center to center dimension for branch
Length of the tee.
