Super Duplex S32760 Seamless Pipe: Why S32760 for seamless pipes
Seamless pipe is the choice for high pressure, high temperature and critical service where a weld seam is not wanted. In Super Duplex S32760, 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 | Duplex tubulars combine strength and chloride resistance. Super Duplex S32760 is picked for seawater firewater, injection and offshore piping. |
|---|---|
| Typical service | Offshore — Firewater and seawater piping. |
| Welding to carbon steel | ER2209 or ER309L(Mo) is used when joining it to carbon steel, under a qualified WPS |
| Matching filler | ER2594 · Zeron 100X |
| Sour service | Listed in NACE MR0175 / ISO 15156-3 within its limits — state it on the order |
