A Monel K500 anchor flange is a forged ring welded into a pipeline to fix it to a structure, made from Monel K500 to ASTM B865. Anchor flanges restrain pipelines against thrust and movement — at pump stations, river crossings and pig traps. They are made to project drawings.

Monel K500 Anchor Flange: Why K500 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 Monel K500, 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 | Nickel-alloy flanges are used where acids, chlorides or heat defeat stainless. Monel K500 is picked for high-strength pump shafts, bolting and springs in seawater. |
|---|---|
| Typical service | Marine — Propeller and pump shafts. |
| Bolting | B7 (coated), B8M or nickel-alloy studs such as Monel K500 from ASTM B865, as the project specifies |
| Welding to carbon steel | A nickel-base filler such as ERNiCr-3 (or ERNiCrMo-3) is used when joining it to carbon steel |
| Matching filler | ERNiCu-7 (non-ageing) |
| Sour service | Listed in NACE MR0175 / ISO 15156-3 within its limits — state it on the order |
