SA-335 P22 · 2¼Cr-1Mo alloy pipe
An ASTM A335 P22 cross is a four-way fitting with branches at 90°, for use with ASTM A335 P22 pipe. ASTM A335 P22 itself is a pipe or plate specification, so the matching cross is made to ASTM A234 WP22 (buttweld) · ASTM A182 F22 (forged) — which is what we supply for P22 lines. Crosses join four pipes in one fitting. They are used less than tees because of stress concentration, but save space in fire-water and utility systems.

ASTM A335 P22 Cross: Why P22 for crosss
Crosses join four pipes in one fitting. They are used less than tees because of stress concentration, but save space in fire-water and utility systems. In ASTM A335 P22, 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 | Carbon and low-alloy fittings suit hydrocarbon, steam and utility lines. ASTM A335 P22 is picked for high-pressure steam and hydrogen service up to about 580 °C. |
|---|---|
| Typical service | Power plants — High-pressure steam lines. |
| Welding to carbon steel | Matching carbon or low-alloy filler is used; joints to stainless need ER309L |
| Matching filler | ER90S-B3 / E9018-B3 |

ASTM A335 P22 Cross — questions buyers ask
Why are crosses less common than tees?
They concentrate stress at four junctions; most designers use two tees unless space is critical.
Can ASTM A335 P22 crosss be welded to carbon steel?
Yes — matching carbon or low-alloy filler is used; joints to stainless need ER309L.
Which standard covers ASTM A335 P22 crosss?
The material is ASTM A234 WP22 (buttweld) · ASTM A182 F22 (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 ASTM A335 P22 cross?
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 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.
