An Incoloy 800 / 800H / 800HT bend is a pipe bend with a larger radius than a standard elbow, made from Incoloy 800 / 800H / 800HT to ASTM B366 WPNIC. Bends of 3D, 5D and larger radius give smoother flow than elbows and suit slurry, pigging and pipeline service. They are induction- or cold-bent from pipe.

Incoloy 800 / 800H / 800HT Bend: Why 800 for bends
Bends of 3D, 5D and larger radius give smoother flow than elbows and suit slurry, pigging and pipeline service. They are induction- or cold-bent from pipe. In Incoloy 800 / 800H / 800HT, 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. Incoloy 800 / 800H / 800HT is picked for furnaces, petrochemical heaters and high-temperature piping. |
|---|---|
| Typical service | Petrochemical — Steam-methane reformer and ethylene furnace piping. |
| 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) |

Incoloy 800 / 800H / 800HT Bend — questions buyers ask
Bend or elbow — what is the difference?
An elbow has a fixed 1D or 1.5D radius to ASME B16.9; a bend is bent from pipe to a larger radius, typically 3D or 5D.
Can Incoloy 800 / 800H / 800HT bends 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 Incoloy 800 / 800H / 800HT bends?
The material is ASTM B366 WPNIC; dimensions follow ASME B16.49 · project specs. Always state both on your purchase order, with the edition if your project specifies one.
What decides the price of a Incoloy 800 / 800H / 800HT bend?
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.
