Hastelloy C22 Nipple: Why C22 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 Hastelloy C22, 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. Hastelloy C22 is picked for mixed oxidising and reducing acids, and weld overlays. |
|---|---|
| Typical service | Chemical processing — Equipment seeing both oxidising and reducing conditions. |
| 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 | ERNiCrMo-10 (AWS A5.14) |
| Sour service | Listed in NACE MR0175 / ISO 15156-3 within its limits — state it on the order |
