In recent years, in particular, in recent years, it has been required that the pressure loss of a duct be reduced and the air flow can be sent as designed by an air conditioning designer. On the other hand, since the duct needs to distribute gas throughout the building or factory, the duct is provided by using various joints and branch pipes. At this time, a branch pipe having various shapes is used. A T-shaped branch pipe is one of them. FIG. 2 shows a conventional T-shaped branch pipe. Gas enters from the main pipe 1 and is diverted to branch pipes 2 and 3 as shown by arrows. At this time, a turbulent flow a occurs at the branch point. The form of the turbulent flow a changes depending on the pressure of the supplied gas, which changes the pressure loss. Therefore, there is a problem that it is difficult to obtain a required air volume as designed.

Branching left and right at the intersection with the main pipe 1 going straight from the direction
In a T-shaped branch pipe composed of pipes 2 and 3,
Facing the main pipe 1 at the intersection where the transferred gas collides and diverts
The inner surface of the branch pipe projects in a conical shape 6 toward the main pipe 1
A T-shaped branch pipe characterized by the following. The present invention will be described in detail with reference to the drawings. FIG. 1 is a longitudinal sectional view showing an example of the T-shaped branch pipe of the present invention. In this example, the T-shaped branch pipe of the present invention is created by remodeling the mesh cross pipe. In FIG. 1, 1 is a main pipe, and 2 and 3 are branch pipes. Reference numeral 4 denotes the remaining portion of the cross pipe (cross pipe) cut from the main pipe. Reference numeral 5 denotes a blind cover which covers the remaining portion of the tube. Reference numeral 8 denotes a spot welded portion for filling the fitting portion of the blind cover 5 to the remaining portion 4 of the tube. In the present invention, the inner surface of the cover 5 projects in a conical shape 6. In other words, the gas transferred from the main pipe 1
The inner surface of the branch pipe facing the main pipe 1 at the intersection
It projects in a conical shape 6 toward it. 7 is the vertex of the conical part. Main 1 or al transfer feed has been air flow strikes the conical portion 6 of the inner surface of the blind cover 5, not cause turbulence for divided homogeneous manner in the left-right shunts very smoothly.
