Alloy 718 · UNS N07718
An Inconel 718 nipple is a short length of pipe, threaded or plain, used to connect fittings, made from Inconel 718 to a specification not yet established. Pipe nipples connect valves and fittings in small-bore lines. Swage nipples (MSS SP-95) also change size between their two ends.

Inconel 718 Nipple: Why 718 for nipples
Pipe nipples connect valves and fittings in small-bore lines. Swage nipples (MSS SP-95) also change size between their two ends. In Inconel 718, 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 718 is picked for very high strength at temperatures up to about 650 °C. |
|---|---|
| Typical service | Oil & gas — Wellhead parts, hangers and high-strength bolting. |
| 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 | ERNiFeCr-2 (AWS A5.14) |
| Sour service | Listed in NACE MR0175 / ISO 15156-3 within its limits — state it on the order |

Inconel 718 Nipple — questions buyers ask
What is a swage nipple?
A nipple that reduces from one size to another, concentric or eccentric, to MSS SP-95.
Can Inconel 718 nipples 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 718 nipples?
The material is a specification not yet established; dimensions follow MSS SP-95 · ASME B36.10 / B36.19. Always state both on your purchase order, with the edition if your project specifies one.
What decides the price of a Inconel 718 nipple?
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 Inconel 718 nipples to NACE MR0175?
Yes. Inconel 718 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.
