An Inconel 825 nipple is a short length of pipe, threaded or plain, used to connect fittings, made from Inconel 825 to ASTM B564. Pipe nipples connect valves and fittings in small-bore lines. Swage nipples (MSS SP-95) also change size between their two ends.

Inconel 825 Nipple: Why 825 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 825, 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 825 is picked for sulphuric and phosphoric acid service, chloride stress-corrosion cracking and sour gas. |
|---|---|
| Typical service | Sulphuric & phosphoric acid plants — Tank linings, agitators, heat-exchanger baffles in fertiliser and acid production. |
| 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-1 (AWS A5.14) |
| Sour service | Listed in NACE MR0175 / ISO 15156-3 within its limits — state it on the order |

What is a swage nipple?
A nipple that reduces from one size to another, concentric or eccentric, to MSS SP-95.
Can Inconel 825 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 825 nipples?
The material is ASTM B564; 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 825 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 825 nipples to NACE MR0175?
Yes. Inconel 825 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 mill certificates as standard, 3.2 with third-party inspection on request, plus dimensional and PMI reports.
