SA-335 P11 · 1¼Cr-½Mo alloy pipe
An ASTM A335 P11 bend is a pipe bend with a larger radius than a standard elbow, for use with ASTM A335 P11 pipe. ASTM A335 P11 itself is a pipe or plate specification, so the matching bend is made to ASTM A234 WP11 — which is what we supply for P11 lines. 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.

FOB / CIF · Nhava Sheva (JNPT), MumbaiASTM A335 P11 Bend — questions buyers ask
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 ASTM A335 P11 bends?
The material is ASTM A234 WP11; 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 ASTM A335 P11 bend?
The steel price, the size and schedule or class, quantity, and the testing and documents required. Send your list and we quote the same working day.
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.
