Direct Answer
Pipe tees create branch connections in piping systems. An equal tee connects three pipes of the same size, while a reducing tee connects a smaller branch to a larger main pipe. Tees are used in oil and gas, chemical plants, water treatment, HVAC, power plants and industrial construction.
Tee Types
| Type | Description |
|---|---|
| Equal tee | All three outlets have the same nominal size |
| Reducing tee | Branch outlet is smaller than main pipe |
| Butt weld tee | Welded directly to pipe ends |
| Threaded tee | Threaded connection for smaller systems |
| Socket weld tee | Used in selected high-pressure small-bore piping |
Selection Factors
Important factors include material, pipe size, branch size, wall thickness, standard, pressure rating and connection type.
Common Materials
Carbon steel tees are common in general industrial piping. Stainless steel tees are used for corrosion-resistant or clean service. Alloy steel tees may be used for high-temperature or special service.
FAQ
What is a reducing tee?

What standard applies to butt weld tees?
ASME B16.9 is commonly used for factory-made butt welding tees.
Can tees be custom made?
Yes. Custom dimensions, wall thickness and material grades can be produced based on project drawings.
