Overview
Mild steel tees are three-way pipe fittings used to combine or divide fluid flow in piping systems. Available in equal tees (all three openings same size) and reducing tees (branch smaller than run), they provide versatile solutions for complex piping networks requiring branch connections.
Features
- Three-way connection for branch piping
- Equal and reducing configurations
- Good weldability for secure installation
- Cost-effective piping solution
- Available in multiple sizes

FAQ
An equal tee, also called a straight tee, has all three openings of the same nominal pipe size, meaning the branch outlet is the same diameter as the main run pipe. Equal tees are used when the branch line needs to carry the same flow volume as the main line, such as in header distribution systems where equal flow is required to multiple branches. A reducing tee, in contrast, has a branch outlet that is one or more pipe sizes smaller than the main run. For example, a 4 by 4 by 2-inch reducing tee has a 4-inch main run and a 2-inch branch outlet. Reducing tees eliminate the need for a separate concentric reducer at the branch connection, saving space and reducing the total number of fittings required. They are commonly used when branching from a large main supply line to a smaller service line, such as in water distribution networks, fire sprinkler systems, and process plant utility headers.
