An ASTM A335 P22 anchor flange is a forged ring welded into a pipeline to fix it to a structure, for use with ASTM A335 P22 pipe. ASTM A335 P22 itself is a pipe or plate specification, so the matching anchor flange is made to ASTM A182 F22 — which is what we supply for P22 lines. Anchor flanges restrain pipelines against thrust and movement — at pump stations, river crossings and pig traps. They are made to project drawings.

When to Choose an Anchor Flange
Anchor flanges restrain pipelines against thrust and movement — at pump stations, river crossings and pig traps. They are made to project drawings.
- Made to drawing
- Usually weld neck on both sides
- Often large and heavy forgings

ASTM A335 P22 Anchor Flange: Why P22 for anchor flanges
Anchor flanges restrain pipelines against thrust and movement — at pump stations, river crossings and pig traps. They are made to project drawings. 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 flanges carry most utility, hydrocarbon and high-temperature service. 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. |
| B16.5 material group | 1.10 — Group 1.10 applies to A182 F22 Class 3. Chrome-moly welds usually need PWHT; the code sets thickness exemptions. |
| Bolting | ASTM A193 B7 studs with A194 2H nuts; B16 with Gr 4 or 7 nuts where the temperature calls for it |
| Welding to carbon steel | Matching carbon or low-alloy filler is used; joints to stainless need ER309L |
| Matching filler | ER90S-B3 / E9018-B3 |

Other ASTM A335 P22 flanges
ASTM A335 P22 Anchor Flange — questions buyers ask
What information is needed to quote an anchor flange?
The project drawing with pipe size, wall, design loads and material, plus the inspection plan.
What pressure rating does a ASTM A335 P22 anchor flange have?
It depends on class and temperature. ASTM A335 P22 forgings are in ASME B16.5 material group 1.10; read your class column in that group's table at the design temperature.
Can ASTM A335 P22 anchor flanges 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 anchor flanges?
The material is ASTM A182 F22; dimensions follow Project drawing. Always state both on your purchase order, with the edition if your project specifies one.
What decides the price of a ASTM A335 P22 anchor flange?
The steel price, the size and pressure 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.
