An SS 304 Weldable Tee is a type of pipe fitting made from Stainless Steel 304 and is used to join three sections of pipe—usually at 90-degree angles—forming a "T" shape. Here's a breakdown of what each part means:
✅ SS 304SS = Stainless Steel
304 = Grade of stainless steel
Composition: Approximately 18% Chromium and 8% Nickel
Corrosion resistance: Good for general-purpose use, especially in non-extreme environments
Weldability: Excellent – SS 304 is one of the most weldable stainless steels
Applications: Food processing, water systems, petrochemicals, general piping, etc.
This means the tee can be welded onto pipes using standard welding methods (e.g., TIG, MIG).
Often features butt-weld ends (especially for industrial piping) or socket weld ends.
A pipe fitting shaped like the letter “T”
It has:
Two ends inline (run)
One outlet at 90 degrees (branch)
Used to either combine or split the flow of fluid.
You might encounter different styles depending on your need:
| Type | Description |
|---|---|
| Equal Tee | All three ends have the same diameter |
| Reducing Tee | The branch is a smaller diameter than the run |
| Butt-Weld Tee | For permanent, strong connections in process piping |
| Socket-Weld Tee | For small pipe diameters, typically under 2 inches |
Standard: ASTM A403 (for SS 304 fittings)
Dimensions: As per ASME B16.9 (for butt-weld), or B16.11 (for socket weld)
Pressure Rating: Depending on wall thickness/schedule (e.g., Sch 10, 40, 80)
Finish: Pickled, passivated, or polished (for sanitary applications)
