A Duplex 2205 bend is a pipe bend with a larger radius than a standard elbow, made from Duplex 2205 to ASTM A815 WPS31803 / WPS32205. Bends of 3D, 5D and larger radius give smoother flow than elbows and suit slurry, pigging and pipeline service. They are induction- or cold-bent from pipe.

Bend or elbow — what is the difference?
An elbow has a fixed 1D or 1.5D radius to ASME B16.9; a bend is bent from pipe to a larger radius, typically 3D or 5D.
Which standard covers Duplex 2205 bends?
The material is ASTM A815 WPS31803 / WPS32205; dimensions follow ASME B16.49 · project specs. Always state both on your purchase order, with the edition if your project specifies one.
What decides the price of a Duplex 2205 bend?
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 Duplex 2205 bends to NACE MR0175?
Yes. Duplex 2205 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.
