Pipe Tee Dimensions

Butt weld pipe Tee allows a 90 degree branch off from a running pipe. This allows for connecting auxiliary equipment to a pipe. A tee is welded on both side to the pipe, leaving the branch open for branch off.

Equal tee (or straight tee ) dimensions

Equal tee

Equre tee (or straight tee), means the branch diameter of this tee is same with the main pipe (Run pipe) diameter of this tee.

Reducing Tee Dimensions

Reducing Tee

Butt weld reducing tee has a branch that is smaller than main run. This allows for branching off to a smaller pipe of equipment from the main run.

ALL DIMENSIONS ARE GIVEN IN INCHES. TOLERANCES ARE EQUAL PLUS AND MINUS EXCEPT AS NOTED.
(1) Out-of-round is the sum of absolute values of plus and minus tolerance.
(2) This tolerance may not apply in localized areas of formed fittings where increased wall thickness is required to meet design requirements of ASME B16.9.
(3) The inside diameter and the nominal wall thicknesses at ends are to be specified by the purchaser.(4) Unless otherwise specified by the purchaser, these tolerances apply to the nominal inside diameter, which equals the difference between the nominal outside diameter and twice the nominal wall thickness.
