Pipe Tee could be ranged from Diameter, connection types, material types.
Classified by Diameter
Pipe tees are mainly divided into two types according to the branch diameter: equal-diameter tees and reducing tees. Equal-diameter tees refer to the nominal diameters of the main pipe and the branch pipe being the same (such as NPS 4″×4″×4″); reducing tees refer to the branch diameter being smaller than the main pipe (such as NPS 4″×4″×3″). Its structure and size design must strictly follow international standards such as ASME B16.9 and MSS SP-43 to ensure installation compatibility and sealing stability under high pressure and complex working conditions.
In addition, the manufacturing standard of the tee not only requires matching of the nominal diameter, but also sets tolerance limits on the center-to-end dimension (C/M) to ensure that the tee can achieve precise structural docking and minimize flow resistance during system assembly. Equal-diameter and reducing tees cover a wide range of sizes, with standard specifications from ½″ to 48″, and are commonly used in various industrial pipelines such as petrochemical, power, shipbuilding, and HVAC.
equal-diameter tees
Equal Tee is a T-shaped pipe fitting with the same diameter as the main pipe. Equal Tee can be divided into straight-through tees (the branch pipe is at right angles to the main pipe) or transverse tees (the branch pipe is at other angles to the main pipe), of which the straight-through type is the most common. The three ends of the pipe fitting are butt-welded to the pipeline system to form a three-way branch or confluence connection. Common materials include carbon steel (ASTM A234 WPB) and stainless steel (ASTM A403 WP304/316L).

Reducing tee
Reducing tee is a T-shaped butt-weld fitting with a branch outlet with a smaller nominal pipe diameter than the two pipe outlets. Unlike a equal-diameter tee, one of the branches tapers in diameter, allowing flow to be divided or combined while reducing pipe size without adding a separate reducer and tee assembly. For example, 4×4×3 represents a reducing tee with two 4-inch pipe ends and a 3-inch branch. Commonly used for pressure gauges, sampling lines

Classified by Connection Types
As per the connection mode, Pipe Tee could be classified by Butt Weld Tee, Socket Weld Tee and Threaded Tee.
Butt Weld Tee
|
Description |
Butt weld tees are T-shaped pipe fittings permanently joined via full‑penetration groove welds, conforming to ANSI/ASME B16.25 bevel specifications (typically 37.5°). All three ends—two run outlets and one branch—are prepared for welding, offering a monotonic, smooth flow line when integrated into piping systems. |
|
Features |
Homogeneous metallurgical continuity: Welds achieve ≥ 95% of base metal strength. Zero internal crevices: Minimizes corrosion or pitting risk. Inspectability: Suitable for radiographic testing (RT) to verify weld integrity. |
|
Applications |
High-pressure hydrocarbon pipelines (ASME B31.4) Nuclear reactor coolant systems (ASME III) Cryogenic services (operating under –196 °C) Vacuum and high-purity systems, where leak-tight welds are critical |
