Monel 400 Nipple: Why 400 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 Monel 400, 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. Monel 400 is picked for seawater, hydrofluoric acid and marine service. |
|---|---|
| Typical service | Marine — Pump shafts, valves and seawater 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 | ERNiCu-7 (AWS A5.14) |
| Sour service | Listed in NACE MR0175 / ISO 15156-3 within its limits — state it on the order |

Monel 400 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 Monel 400 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 Monel 400 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 Monel 400 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 Monel 400 nipples to NACE MR0175?
Yes. Monel 400 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.
