A Hastelloy C22 lateral is a fitting with a 45° branch, made from Hastelloy C22 to ASTM B366 WPHC22. Laterals bring in a branch at 45°, reducing turbulence and pressure drop compared to a tee. Common in drainage, slurry and process lines.

Hastelloy C22 Lateral: Why C22 for laterals
Laterals bring in a branch at 45°, reducing turbulence and pressure drop compared to a tee. Common in drainage, slurry and process lines. In Hastelloy C22, 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. Hastelloy C22 is picked for mixed oxidising and reducing acids, and weld overlays. |
|---|---|
| Typical service | Chemical processing — Equipment seeing both oxidising and reducing conditions. |
| 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 | ERNiCrMo-10 (AWS A5.14) |
| Sour service | Listed in NACE MR0175 / ISO 15156-3 within its limits — state it on the order |

Other Hastelloy C22 pipe fittings
Hastelloy C22 Lateral — questions buyers ask
When is a lateral better than a tee?
Where lower turbulence matters — slurries, solids and gravity drainage.
Can Hastelloy C22 laterals 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 Hastelloy C22 laterals?
The material is ASTM B366 WPHC22; dimensions follow MSS SP-43 / manufacturer standard. Always state both on your purchase order, with the edition if your project specifies one.
What decides the price of a Hastelloy C22 lateral?
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.
Can you supply Hastelloy C22 laterals to NACE MR0175?
Yes. Hastelloy C22 is listed in NACE MR0175 / ISO 15156-3 within its limits; state NACE compliance on the order and it is confirmed on the certificate.
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.
