An Inconel 600 tee is a fitting with a 90° branch that splits or combines flow, made from Inconel 600 to ASTM B366 WPNCI (buttweld) · ASTM B564 (forged). 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

Inconel 600 Tee: Why 600 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 Inconel 600, 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 | Nickel-alloy fittings match nickel-alloy pipe in aggressive media. Inconel 600 is picked for high-temperature oxidation, caustic and nuclear service. |
|---|---|
| Typical service | Furnaces & heat treating — Muffles, retorts and radiant tubes. |
| Welding to carbon steel | A nickel-base filler such as ERNiCr-3 (or ERNiCrMo-3) is used when joining it to carbon steel |
| Matching filler | ERNiCr-3 (AWS A5.14) |

Inconel 600 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 Inconel 600 tees be welded to carbon steel?
Yes — a nickel-base filler such as ERNiCr-3 (or ERNiCrMo-3) is used when joining it to carbon steel.
Which standard covers Inconel 600 tees?
The material is ASTM B366 WPNCI (buttweld) · ASTM B564 (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 Inconel 600 tee?
The alloy 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 or 3.2 certificates available on request / as specified in the PO; dimensional reports as required. PMI can be arranged depending on product and requirements, as specified in the PO.
