SA-335 P22 · 2¼Cr-1Mo alloy pipe
An ASTM A335 P22 elbow is a fitting that changes the direction of a pipe run, for use with ASTM A335 P22 pipe. ASTM A335 P22 itself is a pipe or plate specification, so the matching elbow is made to ASTM A234 WP22 (buttweld) · ASTM A182 F22 (forged) — which is what we supply for P22 lines. 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.

ASTM A335 P22 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 ASTM A335 P22 elbows?
The material is ASTM A234 WP22 (buttweld) · ASTM A182 F22 (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 ASTM A335 P22 elbow?
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.
