Equal and Reducing Steel Pipe Tee
Type of Tee
Tee Type |
Description |
Typical Applications |
Equal Tee |
All three openings have the same diameter |
General branching where flow rates are equal |
Reducing Tee |
Branch outlet has smaller diameter than the main run |
Connecting smaller branch lines to larger main pipelines |
Lateral Tee (Y-Tee) |
Branch connection at 45° angle (Y-shaped) |
Smoother flow transition, less pressure loss |
Female/Male Tee |
Threaded connections on outlets |
Easy installation without welding |
