A Super Duplex 2507 elbow is a fitting that changes the direction of a pipe run, made from Super Duplex 2507 to ASTM A815 WPS32750 (buttweld) · ASTM A182 F53 (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 2507 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.
Which standard covers Super Duplex 2507 elbows?
The material is ASTM A815 WPS32750 (buttweld) · ASTM A182 F53 (forged); dimensions follow ASME B16.9 · B16.28 · 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 2507 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 2507 elbows to NACE MR0175?
Yes. Super Duplex 2507 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 mill certificates as standard, 3.2 with third-party inspection on request, plus dimensional and PMI reports.
