An Inconel 600 swivel ring flange is a flange with a rotating ring that allows bolt holes to be aligned after welding, made from Inconel 600 to ASTM B564. Swivel ring flanges speed up subsea and offshore tie-ins and riser connections, where rotating the whole pipe to line up bolt holes is not possible.

Inconel 600 Swivel Ring Flange: Why 600 for swivel ring flanges
Swivel ring flanges speed up subsea and offshore tie-ins and riser connections, where rotating the whole pipe to line up bolt holes is not possible. 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 flanges are used where acids, chlorides or heat defeat stainless. Inconel 600 is picked for high-temperature oxidation, caustic and nuclear service. |
|---|---|
| Typical service | Furnaces & heat treating — Muffles, retorts and radiant tubes. |
| B16.5 material group | 3.5 |
| Bolting | B7 (coated), B8M or nickel-alloy studs such as Inconel 600 from ASTM B166, as the project specifies |
| 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) |

FOB / CIF · Nhava Sheva (JNPT), MumbaiInconel 600 Swivel Ring Flange — questions buyers ask
Where are swivel ring flanges used?
Mainly in subsea and offshore pipelines, risers and spools where alignment in place is difficult.
What pressure rating does a Inconel 600 swivel ring flange have?
It depends on class and temperature. Inconel 600 forgings are in ASME B16.5 material group 3.5; read your class column in that group's table at the design temperature.
Can Inconel 600 swivel ring flanges 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 swivel ring flanges?
The material is ASTM B564; dimensions follow ISO 27509 / project specs. Always state both on your purchase order, with the edition if your project specifies one.
What decides the price of a Inconel 600 swivel ring flange?
The alloy price, the size and pressure 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.
