Pipe tee
A pipe tee is also called triplet,three way and "T" pieces and it can be used to either combine or split a fluid flow. Most common are tees with the same inlet and outlet sizes, but 'reducing' tees are available as well.
Buying Tips of pipe tee
What should buyers consider for bulk purchase of pipe tees?
- Type of pipe tee—whether welded or seamless
- Standard
- Size and dimension
- Wall thickness
- Material of construction
- Durability and Economical
- High pressure and temperature resistance
- Corrosion resistance etc.
Applications of pipe tee:
Pipe Tees are widely used in various commercial and industrial applications. Industrial applications include:
- Chemical processing
- Petroleum
- Pulp/paper
- Refining
- Textile
- Waste treatment, Marine
- Utilities/power generation
- Industrial equipment
- Automotive
- Gas compression
- Distribution industries
- Industrial plant fluid power systems.
Pipe tee FAQs
Pipe Tee is a type of pipe fitting which is T-shaped having two outlets, at 90° to the connection to the main line. It is a short piece of pipe with a lateral outlet. Pipe Tee is used to connect pipelines with a pipe at a right angle with the line. Pipe Tees are widely used as pipe fittings.
Hot forming
Tees using raw material with a bigger diameter than the finished product, the branch outlet is extruded from pipe while the main body is being pressed.
The outlet's wall thickness can also be adjusted as needed. Applied to Tees with large diameters, heavy wall thickness and/or special material with challenging workability that cannot be manufactured using the hydraulic bulge method.
Bevelled Ends
The ends of all buttweld fittings are bevelled, exceeding wall thickness 4 mm for austenitic stainless steel, or 5 mm for ferritic stainless steel. The shape of the bevel depending upon the actual wall thickness. This bevelled ends are needed to be able to make a "Butt weld".
Welding Bevel acc.to ASME / ANSI B16.9 and ASME / ANSI B16.28
ASME B16.25 covers the preparation of buttwelding ends of piping components to be joined into a piping system by welding. It includes requirements for welding bevels, for external and internal shaping of heavy-wall components, and for preparation of internal ends (including dimensions and dimensional tolerances).
Our in-hourse R&D team developed bevel ends equipment are good using in thickness 2mm to 20mm pipe fittings, guarantee high efficiency and high quality.

These weld edge preparation requirements are also incorporated into the ASME standards (e.g., B16.9, B16.5, B16.34).
ASME B16.25 (BUTT WELD ENDS)
ASME B16.25 sets standards for the preparation of the ends of components that need to be welded together.
Cut square or slight chamfer, at manufacturer’s option for :
- t ≤ 0.19” carbon steel or ferritic alloy steels
- t ≤ 0.12” austenitic alloy steels
Buttweld Fittings general
A pipe fitting is defined as a part used in a piping system, for changing direction, branching or for change of pipe diameter, and which is mechanically joined to the system.
There are many different types of fittings and they are the same in all sizes and schedules as the pipe.
Pipe tee & Crosses size
Pipe Tee, LT, Lateral tee , RT, Reducing tee, Tee fittings accord to ANSI, ISO, JIS and DIN Standards, Measures 1/2 to 56 Inches.
| Pattern | Weld | Seamless |
| Nominal size | 1/2”-48” (DN15-DN1200) | 1/2”-20” (DN15-DN500) |
| Wall thickness | 2-100mm | 2-50mm |
| Bend radius | SCH5S-SCH160 ,XXS | SCH5-SCH160 |
| Type | Tee/reducing tee | Tee/reducing tee |
Most common are tees with the same inlet and outlet sizes, but 'reducing' tees are available as well. it means the one or two ends are differ in dimension.due to thisdimension differ,the makes the tee fittings with the capacity to control the volume when requried.
