A Reducing Tee is a T‑shaped pipe fitting that connects three pipes of different diameters, allowing flow to branch off or combine while changing pipe size in one fitting. It has one main run port and a branch port with a smaller diameter, or both ends of the run and branch are different sizes, eliminating the need for extra reducers.
Types & Structure
Butt Weld Reducing Tee: For medium/large‑diameter pipelines, welded directly to pipe ends (ASME B16.9 standard).
Socket Weld Reducing Tee: For small‑bore high‑pressure systems, with socket ends for fillet welding (ASME B16.11).
Threaded Reducing Tee: For low‑pressure small lines, connected by NPT/BSP threads.
Key Features
Combines tee branch and reducer functions in one component.
Available in carbon steel, stainless steel (304/316), alloy steel, and duplex steel.
Smooth inner flow path, low turbulence, and reliable pressure resistance.
Saves installation space and reduces welding points compared with separate fittings.
Advantages
Simplifies piping layout and reduces assembly time.
Minimizes potential leak points by reducing joints.
Adaptable to high‑temperature, high‑pressure, and corrosive media.
Cost‑effective solution for diameter‑changing branch lines.
Applications
Widely used in oil & gas, petrochemical, power plants, water treatment, shipbuilding, and industrial process piping where flow must branch and reduce diameter simultaneously.
