Super Duplex 2507 Rectangular Tube: Why 2507 for rectangular tubes
Rectangular tube is used for frames, supports and architectural work. In Super Duplex 2507, 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 2507 is picked for seawater and high-chloride service where strength also matters. |
|---|---|
| Typical service | Offshore & subsea — Seawater injection, firewater and subsea piping. |
| Welding to carbon steel | ER2209 or ER309L(Mo) is used when joining it to carbon steel, under a qualified WPS |
| Matching filler | ER2594 (AWS A5.9) |
| Sour service | Listed in NACE MR0175 / ISO 15156-3 within its limits — state it on the order |
