SA-333 Gr 6 · Low-temperature carbon steel pipe
An ASTM A333 Gr 6 tee is a fitting with a 90° branch that splits or combines flow, for use with ASTM A333 Gr 6 pipe. ASTM A333 Gr 6 itself is a pipe or plate specification, so the matching tee is made to ASTM A420 WPL6 (buttweld) · ASTM A350 LF2 (forged) — which is what we supply for A333 Gr 6 lines. Equal tees have the same size branch as the run; reducing tees have a smaller branch. Barred tees add internal bars so pipeline pigs pass the branch.

When to Choose a Tee
Equal tees have the same size branch as the run; reducing tees have a smaller branch. Barred tees add internal bars so pipeline pigs pass the branch.
- Equal and reducing
- Barred tees for piggable lines
- Buttweld, socket weld or threaded

ASTM A333 Gr 6 Tee: Why A333 Gr 6 for tees
Equal tees have the same size branch as the run; reducing tees have a smaller branch. Barred tees add internal bars so pipeline pigs pass the branch. In ASTM A333 Gr 6, the choice usually comes down to the medium and temperature — the rows here are the points buyers check for this exact combination.
| Why this grade | Carbon and low-alloy fittings suit hydrocarbon, steam and utility lines. ASTM A333 Gr 6 is picked for cold-climate and refrigerated piping down to −45 °C. |
|---|---|
| Typical service | LNG & refrigeration — Cold process lines. |
| Welding to carbon steel | Matching carbon or low-alloy filler is used; joints to stainless need ER309L |
| Matching filler | E7018-1 / ER80S-Ni1 |

ASTM A333 Gr 6 Tee — questions buyers ask
What is a barred tee?
A tee with bars welded across the branch opening so a pipeline pig cannot enter the branch.
Can ASTM A333 Gr 6 tees be welded to carbon steel?
Yes — matching carbon or low-alloy filler is used; joints to stainless need ER309L.
Which standard covers ASTM A333 Gr 6 tees?
The material is ASTM A420 WPL6 (buttweld) · ASTM A350 LF2 (forged); dimensions follow ASME B16.9 · B16.11. Always state both on your purchase order, with the edition if your project specifies one.
What decides the price of a ASTM A333 Gr 6 tee?
The steel price, the size and schedule or class, quantity, and the testing and documents required. Send your list and we quote the same working day.
What documents do you supply?
EN 10204 3.1 mill certificates as standard, 3.2 with third-party inspection on request, plus dimensional and PMI reports.
