A pipe tee is a pipe fitting used to combine or divide fluid flow in pipeline systems.
It features one inlet and two outlets arranged at a 90-degree angle, allowing branch connections from the main pipeline.
Pipe tees are essential components in industrial piping systems, providing reliable flow distribution while maintaining pressure integrity under demanding operating conditions.
Depending on the pipeline design, tees are available as equal tees or reducing tees to meet different flow and layout requirements.
Equal Tee – Main pipe and branch pipe have the same diameter
Reducing Tee – Branch pipe has a smaller diameter than the main pipe
Both types are widely used in high-pressure and high-temperature pipeline systems.
