A Super Duplex S32760 elbow is a fitting that changes the direction of a pipe run, made from Super Duplex S32760 to ASTM A815 WPS32760 (buttweld) · ASTM A182 F55 (forged). Elbows come in 45°, 90° and 180° (return) angles. Long-radius (1.5D) is the default for flow; short-radius (1D) saves space. Buttweld elbows follow ASME B16.9; socket-weld and threaded elbows follow ASME B16.11.

Super Duplex S32760 Elbow: Why S32760 for elbows
Elbows come in 45°, 90° and 180° (return) angles. Long-radius (1.5D) is the default for flow; short-radius (1D) saves space. Buttweld elbows follow ASME B16.9; socket-weld and threaded elbows follow ASME B16.11. 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 fittings match duplex pipe in chloride service and strength. Super Duplex S32760 is picked for seawater firewater, injection and offshore piping. |
|---|---|

Super Duplex S32760 Elbow — questions buyers ask
Long radius or short radius elbow?
Long radius gives lower pressure drop and is the default. Short radius is used where space is tight, with a small pressure-rating reduction per ASME B16.9.
Can Super Duplex S32760 elbows be welded to carbon steel?
Yes — ER2209 or ER309L(Mo) is used when joining it to carbon steel, under a qualified WPS.
Which standard covers Super Duplex S32760 elbows?
The material is ASTM A815 WPS32760 (buttweld) · ASTM A182 F55 (forged); dimensions follow ASME B16.9 · B16.11. Always state both on your purchase order, with the edition if your project specifies one.
What decides the price of a Super Duplex S32760 elbow?
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 Super Duplex S32760 elbows to NACE MR0175?
Yes. Super Duplex S32760 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.
