Super Duplex 2507 Plug: Why 2507 for plugs
Hex-head, square-head and round-head plugs close threaded outlets, drains and vents. Made to ASME B16.11. In Super Duplex 2507, 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 | Duplex fittings match duplex pipe in chloride service and strength. Super Duplex 2507 is picked for seawater and high-chloride service where strength also matters. |
|---|---|
| Typical service | Offshore & subsea — Seawater injection, firewater and subsea piping. |
| Welding to carbon steel | ER2209 or ER309L(Mo) is used when joining it to carbon steel, under a qualified WPS |
| Matching filler | ER2594 (AWS A5.9) |
| Sour service | Listed in NACE MR0175 / ISO 15156-3 within its limits — state it on the order |

Super Duplex 2507 Plug — questions buyers ask
Which plug head type should I use?
Hex-head plugs are easiest to tighten with a spanner; square-head suits older equipment; round-head is used where the plug should not be removed.
Can Super Duplex 2507 plugs be welded to carbon steel?
Yes — ER2209 or ER309L(Mo) is used when joining it to carbon steel, under a qualified WPS.
Which standard covers Super Duplex 2507 plugs?
The material is ASTM A182 F53; dimensions follow ASME B16.11. Always state both on your purchase order, with the edition if your project specifies one.
What decides the price of a Super Duplex 2507 plug?
The alloy price, the size and schedule or class, quantity, and the testing and documents required. Send your list and we quote the same working day.
Can you supply Super Duplex 2507 plugs to NACE MR0175?
Yes. Super Duplex 2507 is listed in NACE MR0175 / ISO 15156-3 within its limits; state NACE compliance on the order and it is confirmed on the certificate.
