Hastelloy C276 Welded Pipe: Why C276 for welded pipes
Welded (ERW / EFW) pipe is economical in larger diameters and thinner walls, and accepted by most codes with the right testing. In Hastelloy C276, 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 tubulars handle acids, chlorides and heat. Hastelloy C276 is picked for the most aggressive mixed acids, wet chlorine and hypochlorite. |
|---|---|
| Typical service | Chemical processing — Reactors, heat exchangers and piping for mixed acids. |
| 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-4 (AWS A5.14) |
| Sour service | Listed in NACE MR0175 / ISO 15156-3 within its limits — state it on the order |
